Based the Active Defense Substation Domain Strategy Control Method to against Blackout

Abstract:

In the previous blackout, overload components out of operation often leaded to the expansion of the accident. One active defense substation domain strategy control system was proposed to prevent the N-1 contingencies to N-2 contingencies caused blackout. Through the substation elements states real time analysis , the active defense control strategy was created by learn from the principles and action messages of backup switching equipment, protection and automatic stability control devices. In order to keep the overall system stability, the active defense control strategy was completed by actively put in the standby element or quit part of the overload elements, to make the system into a new equilibrium state. Contrasting these control strategies by PSCAD/EMTDC simulation software, the results presented that this strategy could quickly change the “Close to collapse” zone into the stability states and the building program simple and practical.
