一例汽轮发电机继电保护的缺陷分析及改进

Analysis and Improvement of Defects in the Relay Protection of a Turbo Generator

从某公司汽轮发电机几起电气事故入手,分析其继电保护设计上存在的缺陷,并从中找出需要改进的技术措施,完善继电保护功能的配置,以此提高汽轮发电机组抗御电力系统事故风险的能力,防止大型精密贵重设备损毁事故的发生。

Starting with several electric failures of the turbine generators at some company, defects in the design of its relay protection was analyzed and upgrading technical measures were also sought out, to improve the configuration of relay protection function, enhance the protection capacity of the generator against power system failures and prevent any damaging accidents to large precision and expensive equipment.
