Kesinti Koşullarında Bulanık Mantık Tabanlı Röle Koordinasyon Senaryolarını Kullanarak Minimum Kesintili Elektrik Halka Şebekelerinin Beslenmesi

Öz

Üretimden tüketime kadar son kullanıcı cihazlarını ve şebeke ekipmanlarını arızalara karşı korumak, sürekli ve yüksek kalitede elektrik temini için esastır. Bu nedenle, elektrikli ekipmanların korunması önemli olup koruma görevini yerine getiren cihazlardan birisi de koruma rölesidir.

Endüstriyel tesislerin ve büyük tüketicilerin yüklerindeki aşırı değişkenlik ve dağıtık üretimin yaygın olarak uygulanmasından kaynaklanan değişken üretim, istenmeyen arızaları önlemek için koruma sistemlerindeki rölelerinin uyarlanabilir çalışmasını gerektirmektedir.

Bu çalışmada, daha düşük hesaplama yükü ve dağıtım şebekesi için hızlı hesaplama avantajları ile bulanık mantık tabanlı yeni bir uyarlanabilir röle koordinasyon stratejisi önerilmiştir. Geliştirilen röle koordinasyon stratejisinin performansını değerlendirmek için, PSCAD/EMTDC ortamında gerçek bir ring tipi dağıtım şebekesi simüle edilmiştir. Önerilen sistemin performansı, farklı durum çalışmaları için simülasyon sonuçları ile doğrulanmıştır.

Feeding Electricity Ring Grids with Minimum Interruption Using Fuzzy Logic Based Relay Coordination Scenarios Under Interruption Conditions

Öz

In order to secure continuous and high quality supply of electricity, it is essential to protect end users’ devices and network equipments against malfunction from production to consumption. Therefore, the protection of electrical equipment is essential and one of the devices performing the protection task is called the protection relay.

Industrial plants and large consumers that possess a high variation in loads and variable generation resulting from the widespread implementation of distributed generation requires the adaptive operation of relays in protection systems to prevent undesired malfunctions.

In this study, a novel fuzzy logic based adaptive relay coordination strategy with the advantages of reduced computational load and fast computing for distribution networks is proposed. In order to evaluate the performance of the developed relay coordination strategy, a real-world sample line for a ring-type distribution network has been simulated in PSCAD/EMTDC environment. The performance of the proposed system is validated with simulation results for different case studies.
