摘要
发电机是发电厂的三大主机之一,其安全稳定性在电力企业安全生产中至关重要。大型发电机组采用双重化微机保护装置,为机组的安全稳定运行提供保障。本文从某台1000MW燃煤机组的发电机设备发生故障,造成机组全停的事故入手,对继电保护动作的记录及试验结果进行分析,找出故障发生的原因,提出事故处理方案及防范措施,以避免和减少同类故障的发生。
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.
