1982年4月,康乐县虎关电站二号机建成并网运行时,发生大幅度功率振荡,机组无法稳定运行。我们分别采用改变励磁电流及对谐波他励电源进行滤波等措施后,使功率摆动问题基本得到解决。现将情况介绍如下:
In April 1982, when Huokuan Huokuan Power Station No. 2 was built and connected to the grid, a large power surge occurred and the unit could not operate stably. We used to change the excitation current and harmonic excitation power supply after filtering and other measures to make the issue of power swing basically resolved. Now the situation is as follows:
