摘　　要：针对直流系统中单一测量绝缘电阻方法的不足,提出了一种新型的、可用于识别测量母线、支路绝缘电阻的方法,并给出了平衡电阻、漏电流阈值的限定整定方法,最后通过在PSIM软件中搭建仿真平台,验证了该方法的正确性和准确性.Aiming at the single method of measuring insulation resistance in DC system,this paper proposes a new method which can be used to identify the measurement of bus bar,and bar insulation resistance,and presents a balanced resistance,and leakage current threshold limit setting method Finally through the simula-tion platform in PSIM software,the validity and accuracy of the proposed method are verified.
