YouJiang Hydro-Power Palntblack-Start On Emergency Plan

Accident of large area power cut will cause serious economic losses, the society has a large negative impact. Encounter power failure in large area, combined with the power network structure and the characteristic of hydropower plant, build orderly, reliable hydraulic generator of black start scheme is very necessary.This paper analyzes the impact of hydropower plant the main factors of black start of Youjiang power plant units, do black start power supply to conduct a feasibility analysis, put forward Youjiang power plant black-start scheme selection, demonstrated in without AC power supply when the host device operation stability of hydropower plant. According to prepared units in Youjiang power plant black-start test scheme for Youjiang power plant units, black start with AC electric power plant to conduct a comprehensive analysis and study, choosing Youjiang power plant#2turbine generator for black start with AC electric power plant field test, and success.The research results for the Youjiang power plant units in the establishment of black start scheme provides valuable experience, as the practice of Guangxi power grid black start test of Baise power grid reference, Guangxi power grid blackout, processing has certain guiding significance.
