Abstract

In view of the problem of AC injecting into DC bus in the substation, the harm of AC injection is described, the characteristics of AC injection are analyzed, the detection technology of AC injection is researched, and the insulation monitoring devices for DC power system is designed. The kind of this grounding fault is prevented. A prototype test that it is able to monitor the effective value of AC injection in real time, send out the alarm information of AC injection and improve the reliability of the DC system, which has the advantages of simple operation, accurate measurement and good stability.
