黑启动方案制定及决策支持实用系统

Formulation of Black －start Scheme and Practical Decision Support System

摘要:

结合四川电网的具体情况，研究了黑启动路径生成、启动初期负荷恢复策略，探索体现负荷恢复数量和恢复 速度的实用方法，以及黑启动操作过程中的暂态稳定、过电压等问题的自动校核技术。在此基础上开发了一套电网 大停电后恢复方案制定及决策支持实用化系统。利用该系统制定了四川电网大停电后恢复方案，给出了典型水电机 组作为黑启动电源在启动初期的负荷冲击量参考值以及黑启动初期建议的恢复策略。

Abstract:

Combined with the specific situation of Sichuan power grid，the black － start path generation method and the load recovery strategy in black startup are studied． A practical method for calculating load recovery quantity and recovery speed is presented as well as the automatic checking technology of transient stability，overvoltage and other problems in the operation of black startup． On this basis，a set of black － start scheme formulation and decision support system is developed． The proposed system is used to formulate the recovery plan of Sichuan power grid，and gives the reference value of load impact and the recommended recovery strategy in the early stages of black － start in the system where black － start power supply is hydropower units．
