Güç Sisteminin Tam Çökmesi Sonrasında Yeniden Başlatma Özellikli Güç Üretim Santrallerinin Sistem Restorasyonundaki Önemi

Abstract

Güç sistemleri, elektrik enerjisinin kesintisiz bir şekilde tüketiciye ulaştırılmasını sağlayan ve birbiriyle koordineli çalıştırılan ekipmanların toplamı şeklinde ifade edilen kompleks yapılardır. Ancak bazı durumlarda güç sisteminde tam ya da kısmi olarak sistem çökmesi meydana gelebilmektedir. Bu sistem çökmesi bazen hemen giderilebilirken bazen de giderilmesi uzun sürmektedir. Uzun süren kesintiler sonrasında toplumsal yaşam, gündelik faaliyetler ve üretim faaliyetleri sekteye uğramakta; bu durum maddi olarak büyük bir kayba yol açmaktadır. Güç sisteminin tamamında meydana gelen bir sistem çökmesi sonrasında özenilerek hazırlanmış olan güç sistem restorasyonu planları hemen uygulanmaya başlanmalıdır. Güç sisteminin restorasyonunda kritik bir rol oynayan yeniden toparlanma özellikli güç üretim ünitelerinin konumu ve kapasitesi, sistem çökmesi sonrasında uygulanacak olan restorasyon stratejisine karar vermede büyük bir öneme sahiptir. Yapılan bu çalışmada güç sisteminin tam çökmesi sonrasında yeniden toparlanma özellikli güç üretim santrallerinin sistem restorasyonunda önemini anlamak için gerçek veriler kullanılarak simülasyon çalışması yapılmıştır. Yapılan çalışmada sistem çökmesi ve sistem restorasyonunun uygulama safhalarında güç üretim birimlerinin davranışları incelenmiştir. Güç sistem restorasyon planları hazırlanırken dikkat edilmesi gereken hususlar ile ilgili bilgi verilmiştir.

The Importance of Power Generation Plants with Blackstart on Power System Restoration after Blackout

Abstract

Power systems are complex structures that provide uninterrupted delivery of electrical energy to the consumer and are expressed as the sum of equipment operated in coordination with each other. However, in some cases, a complete or partial system collapse may occur in the power system. While this system blackout can sometimes be fixed immediately, sometimes it takes a long time to fix it. After long interruptions, social life, daily activities and production activities are interrupted; This leads to a huge financial loss. After a system blackout of the entire power system, elaborate power system restoration plans should be implemented immediately. The location and capacity of blackstart power generation units, which play a critical role in the restoration of the power system, are of great importance in deciding the restoration strategy to be applied after the system blackout. In this study, a simulation study was conducted using real data in order to understand the importance of power generation plants with recovery feature in the system restoration after the complete collapse of the power system. In this study, the behavior of power generation units during the application phases of system collapse and system restoration was investigated. Information is given about the points to be considered while preparing power system restoration plans.
