The invention discloses a reactive power voltage optimal operation control method of a distribution network of 10kV or below, which collects the voltage, current, active power, reactive power and Power and other parameters are uploaded to the main control server, and the main control server simultaneously obtains the voltage, current, active power, reactive power and other parameters of the substation transformer forwarded by the reactive power optimization server of the regional power grid through the SCADA interface server to optimize reactive power and voltage Calculated by adjusting the on-load tap-changer of the main transformer of the substation upward or adjusting the switching switch of the reactive power compensation comprehensive measurement and control device of the distribution network downward. The goal of voltage optimization control is changed from "ensure the qualified voltage of the 10kV busbar in the substation" to "ensure the qualified voltage at the end user end of the distribution network". The function layer is balanced in situ.
