宁夏电网黑启动试验研究

Study on black-start tests for Ningxia power network

黑启动(Black-start),是指电力系统全部或部分区域电网因故障全部停电后,不依赖其他电网的帮 助,通过本系统中具有自启动能力机组的启动,带动无自启动能力机组,逐步扩大系统的恢复范围,最终实现 整个系统的恢复。本文简单介绍了宁夏电网黑启动试验的过程,着重对试验结果进行分析,以达到验证黑启 动研究理论计算结果正确性的目的。并找出黑启动过程中存在的薄弱环节,为编制切实可行的黑启动调节操 作方案提供技术指导。

Black-start refers： In electrical power system, overall or the partial regional electric network have completely breakdown, without the other electric networks helping, through the unit with self-starting ability bring about the unit without self-starting ability to start, so as to gradually expand the recovery area of the system and finally realize the overall system restoration. The paper simply introduces black-start test process of Ningxia electric network, analyzes the test resuh to confirm the correctness of black-start research theoretical calculation results. And finds out the weak llnk of black start process existing in Ningxia electric network, provides the technical guidance for establishing practical and feasible black-start dispatch operation plan.
