【 摘 要 】

Shanghai as China's highest load density and largest urban power grid, located in the end position of East China Power Grid, is an important access point of East China UHV AC power grid. Making sure the voltage of UHV power grid placement has enough regulation ability is an important condition for safe operation of the system. The basic measures of system voltage regulation are given and the possible problems of voltage of UHV power grid are analyzed in the actual operation. Using sensitivity analysis method to calculate the ability of Shanghai UHV power grid placement voltage regulation after East China UHV AC target grid operation.
