遵循PDCA循环的山东电网黑启动试验

针对目前电力系统黑启动能力缺乏有效机制以维持与持续改进的现状,提出PDCA模式的试验管理机制,按照风险驱动、事故优先控制和持续改进3个实施原则,指导实施了山东电网的黑启动现场试验。在黑启动试验策划阶段,发现了抽水蓄能机组低负荷下参数失常、开关直流电源缺失、子系统同期并列困难等风险因素,通过分阶段整改在试验前排除了风险。试验实施阶段分方式调整、机组停机、黑启动试验、试验子系统恢复4步骤实施;试验检查与数据分析阶段通过试验录波数据分析了抽水蓄能电站、大型火电机组的黑启动性能,全面验证了试验目标;整改行动阶段修订了原有黑启动方案,制订了新一轮的试验方案与调度操作方案。PDCA循环模式将风险高、代价大、涉及面广的试验通过前馈控制、同期控制与反馈控制3个环节,实现黑启动应急管理闭环,有效保证了试验的顺利实施。

PDCA-based experiment of Shandong power grid black-start

Since the current power system black-start lacks the effective mechanism to maintain and continuously improve, an experiment management mechanism with PDCA pattern is proposed,which guides Shandong power grid black-start experiment according to three principles of risk driven,accident priority control and continuous improvement. During the planning stage,three risk factors were detected and removed: the abnormal parameters of pumped-storage unit under low load,the imperfect DC power for breaks and the diffi...
