Повний текст джерелаDen ständigt ökande penetrationen av vindenergi i elnätet väcker farhågor om elkvalitet och stabil drift av kraftsystemet. Nätkoden (Grid Code) ger strikta riktlinjer för en vindkraftsparks beteende i felfall och under onormala driftsförhållanden.Huvudsyftet med detta projekt är att använda en STATCOM för integration av vindkraftsparker så att nätkoden uppfylls. I detta projekt utformas en yttre reglerstrategi för omriktaren för att reglera spänningen vid anslutningspunkten för vindkraftsparken genom att tillhandahålla reaktiv effektkompensering. Därigenom uppnås en säker drift av nätet eftersom vindkraftparken kommer att följa nätkoden.Den befintliga nätkoden kräver endast styrning av plusföljdskomponenten av strömmen. Denna studie försöker undersöka om detta är tillräckligt samt undersöka möjligheten för att utvidga nätkoden genom att införa ett krav på styrning av negativ-sekvens ström. Resultaten stöder det sistnämnda förslaget. Även användningen av halvledarkomponenter av kiselkarbid-SiC studerades i detta projekt.

Повний текст джерелаEtt problem som finns med microgrid är att de distribuerade produktionsgeneratorerna harett dubbelriktat effektflöde som modifierar felströmmen. Dessutom, inverterbaseradeförnyelsebara energikällor (IB-RES) begränsar det totala felströmsbidraget på grund av desstermiska kapacitet. Eftersom microgrids ska vara operativ vid både anslutning till externt nätsamt önätsdrift behövs skyddsstrategier för att kunna hantera fel, speciellt vid önätsdrift.Om endast IB-RES och batterilager används kan feldrift och normal drift inte särskiljas.Bortsätt från felhantering är det viktigt att studera felbortkoppling för microgrid underbegränsad felström som fås av IB-RES. För att kunna åstadkomma felbortkoppling behöveren IED (från engelskans Intelligent Electronic Device). Det första steget är att finna en metodför att kunna detektera fel under fel nivå modifiering. Denna avhandling tittar på att användanoll- och minusföljds ström sekvensskydd för att detektera fel. För att göra skyddet selektivtkommer det att titta på riktningen av effektflödet. I distributionsnät är det vanligt att haobalanserade laster vilket medför noll- och negativa sekvenskomponenter i nätet. För atttillämpa riktningsskydd för noll och negativ sekvens ström simuleras ett obalanserateffektflöde för att särskilja på feldrift och normal drift vid obalanserad last.Säkerhet och förordningar diskuteras kortfattat i denna avhandling. Det är viktigt att varjeIB-RES har en feltålighet som följer vissa förordningar. Denna förordning förväntassamordna det föreslagna skyddet i micronåt så att pålitlighet, selektivitet och känslighet kanåstadkommas vid nätanslutning och önätsdrift. Denna avhandling visar samordningen mellansäkringar, IED och feltåligheten för växelomriktare.Anpassningsförmågan för det föreslagna skyddet bedöms med avseende på expansion avmicrogrid. Resultatet visar att en expansion av ett microgrid inte kommer att störa denföreslagna samordningen om skyddsmetoden och tidsfördröjningskravet som presenteras idenna avhandling följs. Eftersom det är känt att distributionsnätet kommer att fortsätta ökasin lastkapacitet och mikrogenerering, är det lämpligt att skyddet förväntas varaanpassningsbart vilket innebär att det har en fast IED inställning när nätet expanderas.Analysen genomförs med mjukvarorna electrical transient analysis program (ETAP) ochMatlab Simulink. Kortslutningsanalysen, arbetssekvensen och obalanserad lastflödesimuleras av ETAP, medan skyddsstabiliteten simuleras av Matlab Simulink.

The transient behaviors and negative sequence currents of electric transmission systems are studied in this dissertation. These characteristics will affect the power quality. The transient characteristics studies include the switching over voltage (SOV), the slow front transient (SFT) over voltage, the transient inrush current (TIC), and the transient recovery voltage (TRV). The stable characteristics studies include the negative sequence current (NSC) when the three-phase circuits are operated in normal or in phase-discrepancy conditions. The impacts to the maximum operating time of generators by the NSC are also studied. Firstly, the transient electrical characteristics of the Taiwan-PenHung submarine power cables are studied. The characteristics contain (1) the SOV in normal operation, (2) the SFT over voltage in fault contingency, (3) the TIC in energizing the no-load transformers and shunt reactors, and (4) the TRV in de-energizing the shunt reactors. The results will be compared to the IEEE standards. Secondly, the strategies for the solutions of the Da-Tan power source lines, such as the multi-phase auto reclosing to meet both the minimum load shedding area and the requirement of system safety operation are studied. Finally, the impacts of NSC under the N-0, N-1, N-2 or N-3 conditions of the power source lines on the generator operation time are evaluated. From the study results, the SOV and the TIC of the Taiwan-PenHung submarine power cables satisfy the transient requirements of relative standards. When the shunt reactors are installed, the contactors of current breakers will not re-strike if they open the current breakers. The MPAR of the Da-Tan power source lines could achieve the system requirement. The effects of NSC could be ignored when the four out-linking circuits are operated in N-0, N-1, and N-2 conditions. The generators can be operated in full loading under these conditions. The modifications to the limits of the power plant of the Taipower are also suggested. The results of this dissertation could be the suggestions to the Taiwan Power Company about operation and planning of new submarine power cables, multi-phase auto reclosing of transmission lines, effect of NSC on operation of generators.

This thesis presents the seamless transfer between grid-connected and islanded modes for a single voltage-sourced converter (VSC) based microgrid system. Principles of the control strategies at both modes are introduced where current-mode control for grid-connected operations and autonomous-mode control for islanded operations. The smooth transition from grid-connected mode to islanded mode is based on an islanding detection method that actively injects a negative-sequence current (4% of the rated value) as a disturbance signal via a negative-sequence controller which is adopted as the complementary of the conventional VSC controller. The estimated magnitude of the corresponding negative-sequence voltage at the point of common coupling (PCC) is used as the islanding detection signal. A quantitative analysis based on symmetrical component transformations is proposed to support the feasibility of the islanding detection scheme. For the islanded mode to grid-connected mode transition, a phase compensation scheme that increases or decreases the operating frequency of the VSC is applied for grid resynchronization. The detailed process of the seamless transfer between these two modes is illustrated. Finally, simulations in PSCAD software environment and hardware experiments verify the theoretical analysis.

With more and more distributed energy resources (DERs) being connected to the grid through interface converters, the utility requires the DER generation system to remain grid-connected during grid voltage imbalance to ensure the operating stability of the AC power system. These low voltage ride-through requirements also suggest that the DER generation system injects reactive power to support grid voltages. Traditional reactive power compensation methods can provide request reactive current to meet the low voltage ride-through requirements. However, the resulting peak phase current may exceed the peak rated current of the converter during voltage sag, thus facing the risk of over-current protection tripping of itself. In this thesis, a positive sequence and negative sequence reactive current injection method is proposed to meet the low voltage ride-through requirement. The proposed method can generate the positive sequence and negative sequence reactive current commands so the resulting phase current does not exceed the ampere constraint of the converter,which is very critical for the safe operation of the converter. Its operation principle and control method are explained and analyzed. Simulation and laboratory test results are presented to validate the effectiveness of the proposed method. Comparisons of the proposed method and other low voltage ride-through techniques are also presented.
