Abstract

In recent years, as a result of the rapid growth of energy demand in the regions where the majority of the rivers has increased quite interested in the hydroelectric power plants. A hydroelectric power plant consists of hydraulic turbines, consisting of generators and speed regulation system. Function of the speed regulation system provide to give instantaneously requested energy from depending on the interconnected system. The function of the speed regulator in the system is set the position of the setting wings that control the amount of water entering the hydraulic turbine. Speed regulators are controlled by reference to the active power and frequency parameters of the system. In this study, it has been created model of a hydroelectric power plant and has been obtained transfer function of the entire system. Fuzzy-PID controller PID controller is supplied to the speed regulation system. According to obtained simulation results, it is observed that fuzzy –PID controller provides better speed response than PI controller.

Öz Ayarlamalı Bulanık-PID Denetleyici İle Hidrolik Türbinin Benzetim Çalışması

Abstract

Ülkemizde son yıllarda enerji gereksiniminin hızla artması sonucunda akarsuların çoğunlukta olduğu bölgelerde hidroelektrik santrallerine (HES) ilgi oldukça artmıştır. Bir hidroelektrik santrali temel olarak, hidrolik türbinler, generatörler ve hız regülasyon sistemlerinden oluşur. Hız regülasyon sisteminin görevi, bağlı olduğu enterkonnekte sistemden anlık olarak talep edilen enerjinin verilmesini sağlamaktır. Bu sistemde bulunan hız regülatörünün görevi ise, hidrolik türbine giren su miktarını kontrol eden ayar kanatlarının konumlarını ayarlamaktır. Hız regülatörleri, aktif güç ve sistem frekans parametrelerini referans alarak kontrol edilirler. Bu çalışmada bir hidroelektrik santralin modeli çıkarılmış ve tüm sistemin transfer fonksiyonu elde edilmiştir. Hız regülasyon sistemine PID denetleyici ve Bulanık-PID denetleyici uygulanmıştır. Elde edilen benzetim çalışması sonuçlarına göre bulanık-PID denetleyicinin klasik PID denetleyiciye göre daha iyi hız cevabı verdiği gözlemlenmiştir.
