摘　　要：提出一种在直流电源系统中系统对地电容的测量方法。该方法可以在不影响直流电源系统正常运行的情况下,在线完成测量直流系统对地的各种参数,再根据各种参数计算出系统对地电容的大小。这种方法不需要改变直流电源系统的现有结构,也不需要系统处于停电状态。该方法既安全又可靠,可应用于解决直流电源系统对地电容在线测量的问题。A ground capacitance measurement method for DC power supply system is proposed in this paper. This method can complete the online measurement of various earthing parameters of DC system, without affecting the normal operation of DC power supply system. The system earthing capacitance values can be calculated according to various parameters. It is unnecessary for this method to change the existing structure of the DC power supply system, and neither require the system in a power down state. It is safe and reliable, and can be applied to the online ground capacitance measurement of DC power supply system.
