Traction networks (TN) 25 kV generate higher electromagnetic fields (EMF) with frequency 50 Hz, whose strengths at a standardized height of 1.8 m, as a rule, do not exceed the permissible norms for electrical personnel. In places where railroads routes intersect with high voltage overhead power supply lines (OPL), interference of fields, generated by the traction network and OPL, occurs. This can lead to an increase in strengths and a complication of the EMF spatial structures. The article presents simulation results performed for a complex intersection, while 25 or 2 х 25 kV TN is crossed by a three-circuit 110-220 kV overhead power line at 90 degrees angle. Fazonord software application was used for simulating EMF strengths in points of traction networks and OPL intersection. Based on modeling results the following conclusions have been made: at intersection points of 1х25 kV traction network with a three-chain 110 - 220 kV power transmission line, the electrical field strength does not exceed the value acceptable for electrical personnel and reaches 4.2 kV/m; at the intersection with 2 х 25 kV traction network, this parameter decreases to 2.7 kV/m; the maximum amplitude of the magnetic field at the intersection points increases slightly.

The paper considers an electrical substation with a voltage of 330/110/35 kV. Means of voltage regulation on the substation autotransformer are investigated. The paper considers the means of voltage regulation on autotransformers of the 330/110/35 kV substation to ensure uninterrupted power supply and the desired voltage level on the busbars of consumers. The choice of the optimal version of the on-load tap-changer of the autotransformer is shown. The electric network with voltage of 110 and 35 kV is considered. The power supply center is substation 330 kV. The connection between voltages is provided by three three-phase autotransformers of the ATDCTN200000/330/110 type. Autotransformers are used instead of three-winding transformers to reduce the cost of conductive material and increase transmission power, but unlike three-winding transformers, they have only one voltage control device - load control regulation. Steady-state and emergency modes are investigated. The PowerFactory program has created a network model, which is used to calculate the mode and evaluate the methods of voltage regulation. On the basis of calculations the point of economic flow distribution in which it is expedient to open a network in a normal mode, and on the switch to provide the device of automatic input of a reserve is defined. The principles of control of modes of operation of electrical systems are investigated: minimum costs for generation, transmission and consumption of electricity (technological losses), reliability of operation of electrical systems, quality of electricity. The purpose of this work is to substantiate the optimal operational scheme of the electrical network, the study of the modes of operation of the 330/110/35 kV network. The simulation of steady and emergency modes is performed in the work. The optimal operational scheme of the electric network is substantiated in order to improve the reliability of power supply and ensure the desired level of voltage on the busbars of consumers.

This paper contains a strategy to minimize the power losses in the electrical distribution network of Kosovo. In order to develop the strategy, a model was constructed to simulate an electrical distribution network, and different parameters were included that helped in estimation of the technical power losses in the medium voltage (MV) distribution network. The main objective of this paper is to present approach to minimize technical and non-technical losses in power systems. The analysis of the Kosovo electric power system was performed by means of PSS/E 3.3 software. The results indicate options for reduction of the loses by replacement of old type of transformers and preparation of the MV system for upgrade and change the voltage level from 10 kV to 20 kV. As a first step new 110/10kV transformers can be installed, designed to be reconnected in the future to 110/20kV.

This article describes the features of voltage regulation in electrical networks of 35, 110, 220 kV. The structural diagram of the 35/10/0.4 kV network is presented. The paper also describes the adaptive automatic voltage regulation system which allows regulating the voltage taking into account the actual voltage values at the consumers’ inputs. The structural diagram of the adaptive automatic voltage regulation system in the 0.4 kV electrical network using a boost transformer as an additional means of voltage regulation is given. The system is based on voltage sensors installed in different parts of an eletcrical network sending information on voltage values to to the processing unit which generates a signal for voltage regulating supplied to the executive device and the working body whuch, in turn, change the on-load tap-changer position of a transformer. The paper justifies the need for the enhancement of the adaptive automatic voltage regulation system for different voltage classes wich allows controlling a voltage change at different power supply system levels and regulating voltage level in accordance with this change. For this problem the multi-level adaptive automatic voltage regulation systemis proposed. The system allows regulating the voltage not only in the 0.4 kV network but also in networks of higher voltage classes. The proposed system can be integrated into the structure of intelligent electrical networks.

Introduction. The real electromagnetic situation in a residential area in the process of power supply network operation and health status assessment of population living in the vicinity of overhead transmission lines (OTL) of various voltages and transformer substations (TS) are of current interest. The effect of 50 Hz electric fields (EF) and magnetic fields (MF) on human health has not been sufficiently studied. Material and Methods. Measurement and assessment of 50 Hz EF and MF levels generated by 35, 110 and 220 kV OTL and by 6 kinds of closed-type transformer substations were carried out. Chronic overstrain index was used to assess population health status. Questionnaire study data among residents in the vicinity of 110-220 kV OTL were used for calculation of chronic overstrain index. Results. Closed-type transformer plants don’t generate EMF or exceed 50 Hz EF or MF health standards (HS). Electric field intensity levels exceeding HS were registered under 110 and 220 kV OTL. EMF health standards were not exceeded at a distance of 2 m from 110 kV OTL and 10 m from 220 kV OTL. Magnetic field induction levels did not exceed maximum allowable levels. Significant levels of chronic overstrain were revealed in residents living at a distance of under 300 m from 110-220 kV OTL. Conclusions. Closed-type transformer substations do not generate 50-Hz EMF exceeding health standards. Compliance with the electrical safety requirements of overhead transmission lines (overhead line safety zones) provides compliance with the maximum allowable levels of 50 Hz electric and magnetic fields. Population health risk assessment study among the population in the vicinity of OTL is relevant.

While changing the connection of the power transformators we have to find out if the powered distribution network can accept this change and if it will fulfil the set conditions. Important is to keep the range of permitted voltage on separate distribution points of this network and to find out proportions on separate circuits. This is connected with a circuit load which cannot exceed its limit (transmission capacity). The network is checked against outages of separate circuits (N-1) and we try to find out if other circuits are not overloaded during the transmission of the outaged circuit’s power. We can also suggest various other possible outages. It is also important to find out whether separate distribution points agree with their short-circuit capabilities. Overall we investigate advantages of this circuit. The theoretical part describes the means of calculation of the network functioning and short-circuit conditions. All the calculated results (dispatcher control system Sinaut Spectrum) for the given circuits of power transformators are processed and evaluated in the practical part of the thesis.

Currently, the nodal areas of Neznášov substation and Krasíkov substation, which belong to ČEZd distribution network 110 kV – East, are operand as separate units. In the defined setting, each nodal area comprises of two 400/110 kV transformers. In the case of failure of the transformer T401 or T402, the criterion N-1 for twenty percent of the rated output is not met. Such problem can be solved by parallel operation of nodal areas of Neznášov substation and Krasíkov substation. The principal as well as practical aim of this thesis is to interconnect the bridge operated connection in separated areas into parallel/loop operation of nodal areas (supplied by 400/110 kV transformers). Computing software is used to calculate the steady state and short-circuit conditions in the distribution network 110 kV for separate and parallel operation of mentioned nodal areas. Power flow analysis is aimed at assessment and evaluation of voltage conditions, transformers loading (400/110 kV and 110/vn) as well as 110 kV lines loading. Obtained short-circuit indices is used to examine short-circuit, withstand capability of the 110 kV substation. Finally, benefits as well as drawbacks of the separate and parallel operation are compared and evaluated. If necessary, the technical arrangements are proposed/designed in order to allow parallel operation of nodal areas Neznášov substation and Krasíkov substation.

This Master's thesis is focused on connecting of new power sources into electrical network, particularly, the steady state and allowed voltage variation in network nodes, which occur in steady state before and after connection of a new power source into distribution network, with regard to valid legislation. The new power source in question is the new wind farm Drahany with active power of 45 MW, which should be connected into distribution network 110kV, operated by distribution company E.ON. The aim of this work is to find the most suitable connection point of a wind farm into distribution network, considering transmission capacity of individual electric lines and voltage variations in network nodes, as well as Drahany wind farm's investor's expenses on construction of a connection line to connection point and the distribution network's operator's expenses on modification of the connection point. Also, methods of calculating of electric networks in steady state are described in this paper, particularly, linear calculations, because these are needed for the calculations in E-vlivy program, in which the possible options of Drahany wind farm's connection into network 110 kV, in various places, were modeled. The description of the E-Vlivy program is also included in this paper. The E.ON company's materials form the basis for this Master's thesis, which will later serve as one of the documents needed for Drahany wind farm’s connection point evaluation into distribution network 110 kV.

This Thesis is concerned with the concept of grounding of 110/22 kV transformer station. The aim of the Thesis is to create a ground network for grounding a specified outdoor substation. This 110 kV outdoor substation is formed according to H-scheme and encircles a wide area. In additon to this, an earth potential has to be distributed as equally as possible within the whole area of the substation. The most convenient alternative from the point of view of effective grounding and distribution of potential is a grid network. Therefore, the grid network is the means of grounding which I have chosen as a solution for this issue. In this solution, flat conductor network cables are used to cover the whole substation, with ground rods placed at the points of intersection. Parts of appliance can be then connected to this existing network, thus creating several parallel channels which provide grounding with low resistance. The network is made of common steel zinc-coated stip, size 30 x 4 mm. When proposing a concept of grounding and adjustment of ground electrodes, we have to take account of grounding requirements, stated according to ČSN standards. The proposed earthing system was created in appropriate size in order to meet all these grounding requirements. These requirements are also mentioned and described in a theoretical part of the Thesis. Second part of the Thesis consists of proposed concept of the grounding itself, together with calculated parameters. The grounding has to be carried out according to both safety regulations and electrical appliance requirements. The issue of grounding substations of power system is resolved by the ČSN standards 33 3201 (“Elektrické instalace nad AC 1kV”), 33 2000-4-41 (“Elektrická zařízení – Ochrana před úrazem elektrickým proudem”) and 33 2000-5-54 (“Elektrická zařízení – Výběr a stavba elektrických zařízení – Uzemnění a ochranné vodiče”) and by the PNE company standards 33 0000-4 (“Příklady výpočtů uzemňovacích soustav v distribuční a přenosové soustavě dodavatele elektřiny”) and 33 0000-1 (“Ochrana před úrazem elektrickým proudem v distribuční soustavě dodavatele elektřiny”). These standards apply to creating a concept of grounding and grounding of new, reconstructed or expanded electrical substations of power system.

Distribution network 110 kV owned by E. ON in the area Otrokovice; powered by 110 kV and two variants of involvement contained.The first option is basic involvement, without the use of the bridge. The second option includes involvement with the bridge. The aim of this study is to compare; by calculating the steady-state network operation and short circuit conditions of the network, the involvement of these two options. The thesis is divided into two parts, theoretical and practical. The theoretical part consists of a description of the steady operation of networks of high-voltage and short circuit ratio calculations. Load flow calculations are described by the Gauss-Seidel and Newton iterative method. In the case of short-circuit conditions, the effects of their characteristic values, processes and various methods of calculation are described.In the second part, this theoretical knowledge is applied to input data and dispatching programme with the appropriate calculations of network operation and short circuit conditions. The calculated values are listed in the thesis, on the basis of which an evaluation of the two possible connections is made.

Electrical energy can be obtained by burning coal (thermal power plant), by using nuclear fuel (nuclear power plant) or by using the power of water (hydro power plant). In these cases, the energy obtained by the sources put a shaft of an electrical generator in motion. The generator generates electrical energy – see Figure 1. In the installation, excitation system for the generator is used. The system turns on an uncontrolled rectifier, thyristor-controlled rectifier or AC thyristor regulator dependent on the generator type. The obtained energy is transmitted using a transmission system towards consumers. The transmission yet is made mainly in high-voltage AC energy form (HVAC). In different parts of the transmission network the voltage value may be different. There are so-called high-voltage (420 kV, 220 kV, 110 kV, etc) and medium voltage (20 kV, 6.6 kV, etc.) systems. General consumers consume electrical energy from so-called low-voltage systems (230V, 50Hz or 110V, 60Hz). During the transmission the type of energy does not change, only the value of the voltage changes using transformers.

An energy audit of the electrical network is required in the process of constructing new electrical networks as well as in justifying the reconstruction need of existing ones. In this chapter, the structure of a mobile measuring complex has been developed to conduct an electrical network survey without disconnecting consumers. The complex can be used to inspect 0.4 kV electrical networks and microgrids of the same voltage class and allows data collection on voltage losses and electric power losses in network elements such as a power lines (electric transmission line), and power transformers. The energy audit is conducted without disconnecting consumers in order to avoid an undersupply of electricity as well as to determine the real operating modes of power networks. Ultimately, the use of the developed measuring complex will increase the reliability of the power supply to consumers and ensure the required quality of the electricity supplied to them.

The rural distribution network has deteriorated. This is due to the high failure rate of electrical equipment, high maintenance costs, reduced power quality, and the increased duration of power outages in agricultural production. This leads to a short supply of electricity, downtime of processing equipment, loss of production or production of low-grade products, as well as excessive energy losses during transmission. The important issue is the development of advanced methods for assessing the feasibility and effectiveness for component replacement of power transmission equipment with newer and more modern, reducing electrical energy loss in the distribution network. To solve these problems, various strategies have been developed and studied to improve the reliability of 10 kV overhead power lines by using modern insulators, wires, and supports.

Broadly speaking, a simple electrical diagram of Asco´ I and Asco´ II power nuclear plants could be two power supply bus bars for general equipment classified No-1E, three power supply bus bars class No-1E for the Reactor Coolant Pumps (RCP) and two more bus bars classified 1E for safety related equipment. In normal operating mode, all the five power supply bus bars class No-1E are connected to the main generator (GP1) through two unit transformers (TAG1/2), while the two class 1E power supply bus bars are always connected to an external 110 kV power grid through two auxiliary transformer (TAA1/2). The main generator supplies power to an external 400 kV grid through the main transformer (TP1). The main circuit breaker is placed between the high voltage side of the main transformer and the 400 kV grid. With this configuration, the appearance of an abnormal condition that originates the trip of the main generator and the opening of the main circuit breaker from the external network, involves an electric transfer of the supply bus bars connected to the turbo generator to the external 110 kV power grid. The electric transfer to the external 110 kV power grid will be only possible if the frequency and voltage values are within the allowed range allowed by the grid’s protective relays. Two kinds of electrical transfers are possible: fast transfers and slow transfers. It will be necessary then to evaluate the limit values of voltage and frequency of the power grid that makes the electrical transfer possible in each case. In order to obtain the limit values previously mentioned, the electric system of the plant has been modeled. Different scenarios have been analyzed, taking into account the dynamic behavior of the system components and the delay of the protective relays actuation, verifying the electrical transfer for those situations. This analysis will give enough information to take the correct decisions for future design modifications, and it will assure that the electrical transfer will be done always with success.
