THE ANALYSIS OF THE EFFECT OF TİME DELAY ON STABILITY REGIONS IN AUTOMATIC VOLTAGE REGULATION SYSTEMS WİTH PI CONTROLLERS

Abstract

In electric power systems, changes in active and reactive power can cause fluctuations in terminal voltage, which may unfavorable system stability. Therefore, voltage stability is a crucial indicator for the reliable and efficient operation of power systems. This study investigates the impact of time delay on the stability regions of automatic voltage regulation systems with Proportional–Integral (PI) controllers. Time delay in electric power systems is a critical parameter that directly influences control performance and has significant impacts on system stability and transient response. Within this scope, a weighted geometric center-based approach is adopted using stability boundary locus for determining PI controller parameter values in time-delayed automatic voltage regulation systems. In the proposed approach, the stability boundaries are determined for various delay values, and the resulting changes in PI controller parameters are analyzed. Simulation results demonstrate that time delay shifts the stability boundaries and causes notable differences in transient behavior.

PI KONTROLÖRLÜ OTOMATİK GERİLİM REGÜLASYON SİSTEMLERİNDE ZAMAN GECİKMESİNİN KARARLILIK BÖLGELERİNE ETKİSİNİN ANALİZİ

Öz

Elektrik güç sistemlerinde, aktif ve reaktif güçte meydana gelen değişimler, şebeke terminal geriliminde dalgalanmalara yol açarak sistem kararlılığını olumsuz etkileyebilir. Bu nedenle gerilim kararlılığı, güç sistemlerinin güvenilir, verimli ve sürdürülebilir bir şekilde işletilmesi açısından kritik bir performans göstergesi olarak değerlendirilmektedir. Bu çalışmada, Oransal+İntegral (PI) kontrolörüne sahip otomatik gerilim regülasyon sistemlerinde zaman gecikmesinin sistem kararlılık bölgeleri üzerindeki etkisi analiz edilmiştir. Elektrik güç sistemlerinde zaman gecikmesi, kontrol performansını doğrudan etkileyen kritik bir parametre olup, sistem kararlılığı ve geçici rejim yanıtı üzerinde önemli etkilere sahiptir. Bu kapsamda, zaman gecikmeli otomatik gerilim regülasyon sistemlerinde PI kontrolör parametre değerleri için kararlılık sınır eğrileri kullanılarak ağırlıklı geometrik merkez yöntemine dayalı bir yaklaşım benimsenmiştir. Önerilen yöntem kapsamında, farklı zaman gecikme değerleri için sistemin kararlılık sınırları tanımlanmış ve PI kontrolör parametre değerlerinin değişimi analiz edilmiştir. Simülasyon sonuçları, zaman gecikmesindeki değişimin sistemin kararlılık sınırlarının değiştirdiğini ve geçici rejim davranışında önemli farklılıklar meydana getirdiğini göstermektedir.
