Study on Key Problems at Power System Black Start

Abstract

Developing effective black start plans is significant to the rapid restoration from the power system blackout. This paper makes theoretical research in some key concerns of self-excitation, over-voltage, the impact of starting loads on the voltage and frequency, and stability of the initial small system. The paper also presents countermeasures against these problems. This overview should be very useful to utility operators involved in the development of black start plans.
