1500 V DC Beslemeli Raylı Sistemlerde Gerilim Harmoniği Probleminin AGT Tabanlı Paralel Aktif Güç Fitresi ile Çözümü

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 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.

Solution of Voltage Harmonic Problem in 1500 V DC Powered Rail Systems by IPT Based Parallel Active Power Filter

Energy quality is required for the efficiency and performance of equipment connected to electrical power systems. The main objective of the energy quality is that the voltage and current signal reaching the load has the best sinusoidal waveform. The presence of nonlinear circuit elements in the system leads to the generation of harmonics. Harmonics adversely affect energy quality and reduce system performance. Since DC powered rail systems consist of nonlinear elements, harmonics are formed in the system. In this study, voltage harmonic problem in 1500 V DC supply rail systems is solved with IPT (Instantaneous Power Theory) based parallel active power filter. With the AGT, it is aimed to prevent delays in time. The results were compared with active filter and classical filtering methods. The results obtained by analyzing the system are given on the graphs. The results obtained by operating the circuit with and without filter are given comparatively. The voltage THD (Total harmonic distortion) value of both cases was calculated and the improvement obtained was demonstrated.
