黑启动电站启动调试及继电保护问题探讨

文中以苏北黑启动电站为例，说明了黑启动电站发电机保护配置及设计方案，介绍了站内启动和系统黑启动的试验流程。同时，结合黑启动试验系统与正常运行系统的差异，重点分析了部分保护及自动装置的原理、调试情况和运行注意事项。最后，根据黑启动机组的特殊要求，提出了低频、低压保护的运行操作要求。

Discussion of Start-up Adjustment and Relay Protection in Black Start

Taking black start power station in northern Jiangsu provinces as an example,this paper presented protection configuration and design scheme of black start generator,and introduced the testing process of intra-station start and system black start.Combined with differences between black start test system and the normal operation system,the principles,adjustment situations and operation cautions of some protection and automatic devices were selectively analyzed.Finally,operation requirements of low frequency and low voltage protection were proposed according to the special requirements of black start units.
