摘要
针对传统的变频信号注入法存在的不足,提出了向直流系统母线注入方波信号的波形分析法。根据该方法开发的直流接地故障检测装置在发电厂已取得良好的应用效果。
According to the defect of traditional method of variable frequency signal injection, the method of injecting square wave signal into DC system bus is proposed. DC grounding fault detection device using the method we propose applied in power plant has achieved good effect.
