抽水蓄能电站纯直流黑启动试验及验证

DC Black-Start Test and Verification for Pumped-Storage Power Station

因内蒙古呼和浩特抽水蓄能电站一直未完善纯直流黑启动流程,无顺控流程可执行,自投产以来一直未完成纯直流黑启动试验。以4号机组为例进行纯直流黑启动试验,首先介绍了试验前技术准备及试验过程。试验成功后,依据本次试验步骤,梳理并完善了纯直流黑启动流程,通过试验验证了该流程的可行性和可靠性。

The pure dc black start process has not been perfected in Inner Mongolia Hohhot Pumped-Storage Power Station,and no sequence control process can be executed,so the pure dc black start test has not been completed since commissioning.This paper takes No.4 unit of the company as an example to conduct pure dc black start test.After the success of the test,the pure dc black startup process of the company is summarized and developed according to the test procedures,and the feasibility and reliability of the process are verified.
