关于并网电厂涉网保护定值配合研究

Research on Setting Cooperation for Grid- related Protection of Grid- connected Power Plants

有关整定导则对于涉网保护的保护定值计算及时限配合提出了要求,但针对各个电网公司的不同运行方式,并不是完全适用。以四川电网为例,结合具体涉网保护配置整定,论述了涉网保护的绝大部分较为常见的问题,最终讨论并制定出了涉网保护整定定值和保护动作时间配合的解决方案。

The related setting guides provide the requirements for setting calculation and time coordination of grid - related protection, but according to the different operating mode of each power company, these guides are not completely applicable. Taking Sichuan power grid as example and combined with the detailed configuration and setting of grid - related protection, the most common problems of grid - related protection are proposed, and finally the solutions for setting values and actuation time coordination of grid - related protection are discussed and formulated.
