Generator is one of the three core equipment of power plant. It is a primary electrical that can convert me-chanical energy into electrical energy. Large generator equip with Dual-computer protection device. Its safe operation is very important to guarantee the safe and stable operation of power grid. This article firstly discusses an 1000MW generator acci-dent which causing the unit to a full stop, then analyzes the reasons that contributes to the problems focus on the records of the Relay protection action and the experiments’ results. Therefore , this article puts forward the method to deal with the fault is put forward, in order to avoid and reduce the occurrence of the same kind of failure.
