摘　　要：针对2012年4月22日胶东站换相失败问题。通过对直流系统建模,并将换相失败过程的系统参数代入模型中进行了分析和计算,提出预防逆变站换相失败的措施。分析结果表明:逆变站发生换相失败故障,将导致银川东换流站直流电流增大,直流输电输送功率减少,并对整流侧交流系统产生干扰。Aiming at the problem of commutation failure in Jiaodong converter substation, by DC system modeling, analyzes and calculates with the system parameters in the process of commutation failure substituting the model parameters, puts forward the measures of preventing commutation failure in converter substation. The analysis result shows that commutation failure happened at converter substation, can bring on the DC current increase, the DC transmitted power decrease and the AC system of commutating side influence in Yinchuan Eastem converter substation.
