Abstract

Abstract: Since the unit No.1 of Huadian Fujian Shaxian Chengguan Hydropower Company Limited was put into operation, the deexcitation resistor was damaged first time. Aiming at the happened problem, the reason of the fault was analyzed. Using the exclusive method, it was diagnosed that the fault is deexcitation resistor failure preliminarily. After the deexcitation resistor was replaced by new one, the unit operates normally.

Key words: excitation system, deexcitation circuit, rotor over-voltage, damage of deexcitation resistor, reason analysis
