Analysis and Handling of Reverse Power for a Nuclear Power Turbine Generator Unit

介绍了某核电厂汽轮机发电机组逆功率问题,对试验控制逻辑及过程进行了分析。调节系统设置的用于表决back to nominal speed信号触发的延时时间过短,机组在转速调节尚未达到稳定状态时重新并网是导致逆功率问题发生的根本原因,给出了可以解决该问题的处理方案。

The paper introduces a problem of reverse power for some nuclear power turbine generator unit and analyzes the control logic and test process. The root cause for reverse power is the time delay used to trigger the back to nominal speed signal too short and re-connecting to grid when the turbine speed has not reached the stability state.A solution to solve the problem is given in this paper.
