Voltage monitoring and reactive voltage regulation and control is an important task in power system operation and control. According to 500 kV 3/2 connection of Zhiyan transformer substation, maximum theo-retic bus voltage difference is calculated. Through one-by-one examination of all links of voltage acquisition, the cause of excessive voltage difference of 500 kV buses in Zhiyan transformer substation is detected, name-ly the excessive error of bus measurement and control device. After accuracy regulation, the voltage differ-ence returns to normal scope.
