Determination of moment for power system separation control action during an out-of-step condition

Abstract

Studies aimed at the determination of timepoints that are favorable for the implementation of control actions are presented in the article. The formation of control actions with angle of transmission δ in the area of zero value is suggested for the devices of liquidation of out-of-step regime for this purpose. The developed method of determination of moment for power system separation control action is tested via COMTRADE oscillograms, which were obtained at digital-to-analogue physical complex OAO NIIPT.
