Abstract:

Purpose:To assess the effects of manipulating the loading of successive sets of midthigh clean pulls on the potentiation capabilities of 7 international-level US weightlifters (4 men, 3 women).Methods:Isometric and dynamic peak-force characteristics were measured with a force plate at 500 Hz. Velocity during dynamic pulls was measured using 2 potentiometers that were suspended from the top of the right and left sides of the testing system and attached to both ends of the bar. Five dynamic-performance trials were used (in the following order) as the potentiation protocol: women at 60, 80, 100, 120, and 80 kg and men at 60, 140, 180, 220, and 140 kg. Trials 2 vs 5 were specifically analyzed to assess potentiation capabilities. Isometric midthigh pulls were assessed for peak force and rate of force development. Dynamic lifts were assessed for peak force (PF), peak velocity (PV), peak power (PP), and rate of force development (RFD).Results:Although all values (PF, PV, PP, and RFD) were higher postpotentiation, the only statistically higher value was found for PV (ICCα = .95, P = .011, η2 = .69).Conclusions:Results suggest that manipulating set-loading configuration can result in a potentiation effect when heavily loaded sets are followed by a lighter set. This potentiation effect was primarily characterized by an increase in the PV in elite weightlifters.

Abstract:

This paper presents a dynamic model of a monopropellant-based chemofluidic power supply and actuation system. The proposed power supply and actuation system, as presented in prior works, is motivated by the current lack of a viable system that can provide adequate energetic autonomy to human-scale power-comparable untethered robotic systems. As such, the dynamic modeling presented herein is from an energetic standpoint by considering the power and energy exchanged and stored in the basic constituents of the system. Two design configurations of the actuation system are presented and both are modeled. A first-principle based lumped-parameter model characterizing reaction dynamics, hydraulic flow dynamics, pneumatic flow dynamics, and compressible gas dynamics is developed for purposes of control design. Experimental results are presented that validate the model.

Abstract:

The national power can be considered in a static and dynamic aspect as well. This applies to all dimensions of the national power, both military and non-military, including the economic one presented in this article. The national power, treated in a static sense as one of the leading features of the state and estimated over a given period, can only be descriptive. On the other hand, it gains a new dimension in a dynamic sense that consists in the possibility of developing the research into a prognostic area. Therefore, this approach to the issue of the national power has been presented here. The research hypothesis is that on the basis of available statistical data it is possible to construct a verifiable dynamic descriptive model of the national economic power, which enables comparative analyses of the group of selected countries. The research took advantage of statistical methods of selecting variables for linear models and methods of system analysis, including multi-criteria, taxonomic method of comparative analysis. Analyses that have been performed allowed to create a dynamic descriptive model of the national power in the economic sphere. The constructed model was positively verified based on the available figures for the selected group of countries. The conducted calculations suggest that it is possible to use this model for further analyses of the national power in the economic sphere.

Abstract:

The complex dynamic characteristics of a shipboard power system (SPS) are not only related to its continuous dynamics but also influenced by discrete control behavior. Especially, during combat mission execution of high-power pulse loads (HPPLs), their operation plan as a sequence of discrete control events will cause successive abrupt changes in the continuous dynamics of SPS due to the sudden and intermittent nature of the external attacks, which requires overall comprehension of the hybrid dynamics evolution process driven by discrete events. In this paper, considering the zonal distribution structure of SPS and the influences of extreme events on the discrete dynamics of each zone, the extended hybrid models for each zone, including normal operation configuration and fault configuration, are obtained based on the hybrid automata theory. Then, the global hybrid model of SPS is developed. The mapping relationship of discrete state transition to the continuously controlled system is analyzed to reconstruct the set of differential equations model of the continuous system for the purpose of simulation. Two case studies are carried out to perform the simulation under the proposed hybrid model. It is demonstrated that this proposed method can reveal the operating characteristics of the hybrid dynamic evolution process driven by discrete events, both in normal operation and pulse loads operation. Although the precise measure of discrete states of SPS can be challenging to obtain, especially during the confrontation phase, the proposed method still provides valuable insights on evaluating the sophisticated dynamics of an SPS.

Abstract:

In a renewable-energy-penetrated power system (RPPS), inverter-based resources (IBRs) pose serious challenges to power system stability due to their completely different dynamic characteristics compared with conventional generators; thus, it is necessary to study the dynamic interactions between IBRs and power systems. Although many research efforts have been dedicated to this topic from both power electronics and power system researchers, some research from the power electronics field treats the external power system as a voltage source with an impedance, therefore ignoring the dynamic characteristics of a power system, while most of the research from the power system field applies simulation-based methods, for which it is difficult to directly interpret the interaction mechanism of IBRs and external system dynamics. Thus, none of these studies can explore the accurate dynamic interaction mechanism between IBRs and power systems, leading to performance degradation of IBR-integrated power systems. Our study takes into account the dynamic characteristics of both IBRs and the external power system, resulting in the development of a new open-loop transfer function for RPPSs. Based on this formulation, it is observed that under certain operating conditions, the dynamic interactions between the inverter and the power system help enhance IBR-penetrated power system stability compared with the case for which the external power system is controlled as a voltage source. The study also reveals how the inverter (phase-locked loop, control parameters, etc.), external power system (network strength) and penetration ratio in an IBR-penetrated power system affect the dynamic interactions between IBRs and the external power system using the proposed quantified interaction indices.

Abstract:

This paper presents the optimized design, economic feasibility and dynamic modeling of a grid-tied captive hybrid renewable energy power plant for a Pakistani industrial area. Since the proposed plant, encompasses a photovoltaic (PV) array - as its main component - and for an efficient and reliable operation many issues - including industrial load variations and expected dynamics - should be investigated before its implementation. In this context, Homer Pro software is utilized in the design and economic optimized sizing of the PV array, and the PVWatts is used in land requirement analysis. The designed grid-tied plant is modeled in the MATLAB/Simulink using Simscape blocksets to investigate the plant’s dynamic behavior due to typical practical disturbances. The obtained results reveal that the plant has a low per-unit energy cost and provides significant savings. Results of dynamic simulation show that the plant can respond to the ramp-up and ramp-down load variations in industrial settings. Moreover, the plant has a fast response to step changes in irradiance; proving that the proposed plant is reliable and suitable candidate for fulfilling the designated load.

Abstract:

In this study, the dynamic model for the herringbone planetary gear transmission system is established by the lumped parameter method based on the system dynamics and the Lagrange equation, and the impact of the support stiffness and the torsional stiffness on dynamic characteristics is studied. The research results have a guiding significance for the design of the herringbone gear transmission system. In this model, the herringbone gear is treated as a special gear coupled by 2 opposite helical gears, where the stagger angle, comprehensive meshing error, support stiffness, support damping, and load inertia are considered in the analysis of dynamics. Moreover, the dynamic characteristic of the carrier is considered as well. By calculating the meshing force curve of the transmission system, the impact of the stagger angle, supporting stiffness, and the torsional stiffness on meshing force and load sharing coefficient is analyzed. The results show that the stagger angle has an obvious impact on load sharing coefficient while it has little impact on maximum meshing force. And the support stiffness has a more obvious impact on the dynamic characteristics of the system. The recommendary support stiffness of the system is that all of the support stiffness of the sun gear, planetary gear, ring gear, and carrier is 107 N/m. The torsional stiffness has little impact on the dynamic characteristics of transmission system, except the torsional stiffness of planetary gear, and carrier has an obvious impact on load sharing coefficient. The commercial software ADAMS carried out dynamics analysis of the transmission system to verify the necessity validity of the theoretical analysis.

Abstract:

This article is a review devoted to the theory and practice of the application of power shell elements (PSE) in pneumatic drives (PD). She makes acquaint the reader with the main provisions of the theory of PD, performed on the PSE. The review briefly presents materials on the development of dynamic mathematical models (DMM) of power units (PU) of shell PDs (SPD), based on the use of static characteristics of SPD, an assessment of the advantages and disadvantages of PU based on traditional pneumatic cylinders (PC) and PSE is given. The main attention in the review is paid to the solution of the problem of creating PU on PSE with the required quality indicators at the design stage, when it is necessary to take into account the properties of compressed gas. For this, an original methodology for the development of nonlinear DMMs for various typical variants of the midrange is proposed, the basis of which is a number of provisions of the theory of gas dynamics. Without invoking this theory, it is impossible to ta into account the properties of compressed gas (compressibility of the working medium, dependence on temperature and gas flow rate in the shell, the nature of the gas expansion processes), and, therefore, to reliably describe the state of unsteady gas processes inside the shell and develop a DMM of the PU, to a sufficient taking into account the mentioned properties. Since the topic of this review is intended mainly for engineers who develop SPD (theoreticians and practitioners), the review also contains materials on the linearization of the found nonlinear DMMs. As a result of linearization, nonlinear DMMs are transformed into transfer functions for displacement of the output coordinate and effort. The correctness of the linearization carried out is confirmed by the results of experiments. The review briefly discusses several options for pneumatic supply systems for SPD. Here, of particular interest for a specialist is the material on imparting invariance properties to SPDs to air intake from the atmosphere nd discharge of exhaust air into the atmosphere, which significantly expands the scope of SPDs and reduce their cost.

The goal of the power management control strategy is to control the un-directional DC-DC converter and bi-direction DC-DC converter to operate in suitable modes according to the condition of solar cell and battery, so as to coordinate the two sources of solar cell and battery supplying power and ensure the system operates with high efficiency and behaviors with good dynamic performance. A 500W experimental prototype of photovoltaic power system was built in the lab. Experimental results are shown to verify the effectiveness of the proposed power management strategy..

Abstract:

A large number of inductive loads need the reactive power, and the amount of the reactive power compensation is different in a state of work. The traditional static reactive power compensator is difficult to meet the needs of the reactive power compensation for the composite load reactive. Therefore, a dynamic reactive power compensation method of the composite power load is proposed in this paper. The following works have been done in the study: principle of dynamic reactive power compensation control method, topological structure of dynamic reactive power compensation device, and implementation of the dynamic reactive power compensation control method.

Abstract:

A method how to perform an entire structural and hydraulic diagnosis of prototype Francis power machines is presented and discussed in this report. Machine diagnosis of Francis units consists on a proper evaluation of acquired mechanical, thermal and hydraulic data obtained in different operating conditions of several rotary and non rotary machine components. Many different physical quantities of a Francis machine such as pressure, strains, vibration related data, water flow, air flow, position of regulating devices and displacements are measured in a synchronized way so that a relation of cause an effect can be developed for each operating condition and help one to understand all phenomena that are involved with such kind of machine. This amount of data needs to be adequately post processed in order to allow correct interpretation of the machine dynamics and finally these data must be compared with the expected calculated data not only to fine tuning the calculation methods but also to accomplish fully understanding of the influence of the water passages on such machines. The way how the power plant owner has to operate its Francis machines, many times also determined by a central dispatcher, has a high influence on the fatigue life time of the machine components. The diagnostic method presented in this report helps one to understand the importance of adequate operation to allow a low maintenance cost for the entire power plant. The method how to acquire these quantities is discussed in details together with the importance of correct sensor balancing, calibration and adequate correlation with the physical quantities. Typical results of the dynamic machine behavior, with adequate interpretation, obtained in recent measurement campaigns of some important hydraulic turbines were presented. The paper highlights the investigation focus of the hydraulic machine behavior and how to tailor the measurement strategy to accomplish all goals. Finally some typical recommendations based on the experience obtained on previous diagnostic reports of Francis turbines are performed in order to allow a better and safe operation of these power plant units.
