    • A thyristor starting device (100) includes: a converter (1) which converts AC power supplied from an AC power source (e1) into DC power; a DC reactor (3) which smooths a DC current; an inverter (2) which converts the DC power provided from the converter (1) through the DC reactor (3) into AC power, and supplies the AC power to a synchronous machine (4); a gate pulse generation circuit (40) which generates a gate pulse to be provided to thyristors of the converter (1) and the inverter (2); a control unit (20) which sets a phase control angle of the gate pulse to be provided to the thyristors of the converter (1), by controlling a current of the converter (1) such that the DC current flowing into the DC reactor (3) matches a current command value; and an abnormality detection unit (50) which compares a detection value of the DC current with the current command value, and determines an abnormality in the gate pulse based on a comparison result.
    • 晶闸管启动装置(100)包括:转换器(1),其将从AC电源(e1)提供的AC电力转换为DC电力; 直流电抗器(3),使直流电流平滑; 将从转换器(1)提供的直流电力通过直流电抗器(3)转换为交流电力的逆变器(2),并将AC电力提供给同步电机(4); 栅极脉冲产生电路(40),其生成要提供给转换器(1)和逆变器(2)的晶闸管的栅极脉冲; 控制单元(20),其通过控制转换器(1)的电流使得流入直流电抗器(1)的直流电流(...)来设定要提供给转换器(1)的晶闸管的栅极脉冲的相位控制角, 3)匹配当前命令值; 以及异常检测单元(50),其将直流电流的检测值与电流指令值进行比较,并且基于比较结果确定门脉冲中的异常。
