Distribution Substation Performance Improvement: Case Study

Electric power quality is one of the most challenging topics for electrical companies throughout the world. The planning and the structure of distribution stations (DS) play an important role in the power quality and the performance of these stations. This paper studies the structure and the components of the distribution substation and presents some technical ideas in order to enhance its performance. The effect of (33/0.4) kV transformer, ONAF transformers, and power factor correction, will be discussed for higher power distribution reliability in terms of peak-load management and power delivery interruptions. The medium voltage outdoor distribution station of (33/11) kV in AL-Tur in Palestine is adopted as a case study to illustrate the proposed technical actions.
