Öz Enerji kalitesi elektrik güç sistemlerine bağlı ekipmanların verimi ve performansı için gerekmektedir. Enerji kalitesinin ana hedefi yüke ulaşan gerilim ve akım sinyalinin en iyi derecede sinusoidal dalga şekline sahip olmasıdır. Sistemde nonlineer devre elemanlarının varlığı harmoniklerin üretilmesine neden olmaktadır. Harmonikler enerji kalitesini olumsuz etkileyerek sistem performansını düşürmektedir. DC beslemeli raylı sistemler nonlineer elemanlardan oluştuğu için sistemde harmonikler oluşmaktadır. Bu çalışmada 1500 V DC Beslemeli Raylı Sistemlerde Gerilim Harmoniği Probleminin AGT (Anlık Güç Teorisi) Tabanlı Paralel Aktif Güç Fitresi ile Çözümü benzetim yoluyla yapılmıştır. AGT ile zamanda oluşabilecek gecikmelerin önüne geçilebilmesi hedeflenmiştir. Aktif filtre ile klasik filtreleme yöntemleri karşılaştırılarak sonuçlar elde edilmiştir. Sistem analiz edilerek elde edilen sonuçlar grafikler üzerinden verilmiştir. Devre filtreli ve filtresiz olarak çalıştırılarak elde edilen sonuçlar karşılaştırmalı olarak verilmiştir. Her iki duruma ait gerilim THD (Toplam harmonik distorsiyon) değeri hesaplanarak elde edilen iyileştirme ortaya konulmuştur.

The increasing penetration of wind energy to the conventional power system due to the rapid growth of energy demand has led to the consideration of different wind turbine generator technologies. In fault conditions, the frequency of the power system decreases and eventually leads to speed differences between the grid and the interconnected wind generator. This can result to power system problems such as transient instability (TS). This paper focuses on enhancing the TS of a permanent magnet synchronous generator (PMSG)-based power system during 3ph fault conditions using FACTS devices. The power system considered is connected to a large wind farm which is based on PMSG. Critical clearing time (CCT) is used as an index to evaluate the transient state of the system. Under the study of an IEEE-14 bus system using PSAT as a simulation tool, the integrated CCT with PMSG-based wind turbine is improved with three independent FACTS devices. One of the synchronous generators in the test system has been replaced at random with the PMSG-based wind turbine which is meant to generate an equivalent power. Time domain simulations (TDSs) were carried out considering four study cases. Simulation results show that the (CCT) of the system with the FACTS devices is longer than the CCT without them, which is an indication of TS improvement.

“…For solving this case, flexible AC transmission system (FACTS) devices were proposed to be implemented to the power grid for improving the stability of the power system. Static synchronous compensator (STATCOM) is one of the most suitable devices that can be used not only to maintain the voltage at the connected bus but also to improve the dynamic stability of the system [2][3][4][5][6][7]. STATCOM is applied to improve the operational and control performance of the power system such as power transfer capability, voltage regulation, reactive power management, stability limits, power factor improvement, etc [2].…”

One of STATCOM’s advantages is its quick response to disturbances in the power systems. The controller of STATCOM is commonly a PID controller. However, the PID controller is usually only highly effective at one or some operation points. In order to improve operational efficiency of the controller of STATCOM, the proposed ANFIS-PSO and ANFIS-GA controllers have been studied and applied to the studied power system. To demonstrate the performance of the proposed controllers, simulations of the voltage response in time-domain were performed in MATLAB to evaluate the effectiveness of the designed controllers for STATCOM. The simulation results showed that the proposed controllers can be used to improve the system stability as well as the voltage quality more effectively than the conventional PID controller. The ANFIS PSO controller carried out the best response after the occurrence of a three-phase short circuit fault.
