大亚湾及岭澳两核电站机组同步并网特点及相关故障分析

The characteristic and relevant fault analysis for the microgovernor synchronization of Daya Bay Nuclear Power Station and Ling’ao Nuclear Power Station

介绍了大亚湾核电站及岭澳核电站汽轮机控制系统在机组并网、同步及带最小负荷过程中的控制原理,并首次用时序图的形式把控制机理直观地表示出来。针对大亚湾核电站1号机组在并网过程中出现的故障进行了分析说明。

In Daya Bay and Ling＇ao Nuclear Power Station, the Microgovernor has the control functions such as synchronization, block loading etc. The control principle of the Microgovernor is right described by sequence diagram for the first time. That the fault occurred in the synchronization process of Daya Bay Nuclear Power Station unit 1 is also analyzed and illustrated.
