Electromechanical low-frequency oscillations are among the primary concerns for the stability of large-scale interconnected power systems. Depending on the system components they affect, these low-frequency oscillations can be classified as local oscillations, inter-area oscillations, control mode oscillations, or torsional mode oscillations. Inter-area oscillation occurs when generator groups in two areas connected by weak tie lines involving large amount of power transfer experience oscillations relative to each other. While Power System Stabilizers (PSS) are an effective solution for damping local modes by adding an additional damping signal to the excitation system of generators, they are insufficient in dampening inter-area modes. This is due to the lower observability of inter-area modes in local signals.

Thyristor Controlled Series Compensators (TCSC) devices, which are used in power systems for purposes such as power transfer control and transient stability, also contribute to the damping of inter-area modes when direct access to signals with high observability (global signals) of inter-area modes are provided. Effective results in damping inter-area oscillation modes are achieved through the coordinated use of global signal based Power System Stabilizers (PSS) and TCSC devices. In this study, a wide-area damping control system based on TCSC was designed for a 2-area 4-generator power system, which is used as a benchmark model in inter-area oscillation studies. The damping performance was initially evaluated with only TCSC active in the system. Subsequently, a global signal-based PSS was added to the system via TCSC, and the performance evaluation was conducted again. Simulation results demonstrate that the coordinated use of global PSS and TCSC successfully dampens inter-area oscillation modes and improves inter-area power transfer.

Güç Sistemlerinde Alanlar-Arası Salınımlar için bir Tristör Kontrollü Seri Kapasitör (TCSC) Tabanlı Geniş-Alan Sönümleme Sistemi Tasarımı

Elektromekanik düşük frekanslı salınımlar, büyük çaplı enterkonnekte güç sistemlerinin kararlılığı için başlıca kaygılar arasındadır. Etki ettikleri sistem bileşenlerine bağlı olarak bu düşük frekanslı salınımlar, lokal salınımlar, alanlar arası salınımlar, kontrol modu salınımları veya burulma modu salınımları olarak sınıflandırılabilirler. Alanlar arası salınım, birbirlerine zayıf bağlantı hatları ile bağlı yüksek miktarda güç transferinin yapıldığı iki alanda bulunan generatör gruplarının birbirlerine karşı salınımları ile meydana gelmektedir. Generatörlerin uyarım sistemine ek bir sönümleme sinyali eklenmesi için kurulan güç sistemi kararlaştırıcıları (PSS) lokal modların sönümlendirilmesinde oldukça etkili bir çözüm iken alanlar arası modların sönümlendirilmesinde yetersiz kalmaktadırlar. Bunun nedeni alanlar arası modların gözlemlenebilirliğinin lokal sinyallerde düşük olmasıdır.

Güç sistemlerinde güç aktarım kontrolü ve geçici durum kararlılığı sağlama gibi amaçlarla kullanılan Tristör Kontrollü Seri Kompanzatör (TCSC) cihazlar, alanlar arası modların gözlemlenebilirliğinin yüksek olduğu sinyallere (global sinyaller) doğrudan erişimi sağlandığında bu modların sönümlendirilmesine de katkı vermektedirler. Global sinyal tabanlı PSS ve TCSC cihazların koordineli kullanımıyla alanlar arası salınım modlarının sönümlendirilmesinde etkili sonuçlar alınmaktadır. Bu çalışmada alanlar arası salınım çalışmalarında referans model olarak kullanılan 2 alanlı 4 generatörlü güç sistemi için TCSC tabanlı bir geniş alan sönümleme kontrol sistemi tasarlanmıştır. Sönümleme performansı öncelikle sistemde sadece TCSC aktif iken değerlendirilmiştir. Sonrasında global sinyal tabanlı bir PSS, TCSC üzerinden sisteme eklenmiş ve performans değerlendirmesi yeniden yapılmıştır. Benzetim sonuçları ile global PSS ve TCSC’nin koordineli kullanımıyla hem alanlar arası salınımın modlarının başarıyla sönümlendirildiği hem de alanlar arası güç aktarımının iyileştirildiği gösterilmiştir.
