A transmission line overload control program based on wide area information

When taking emergency control measures to eliminate the overload circuits, it is necessary to ensure the normal lines of power system won´t overload. Therefore, it´s necessary to analyze the security of the normal lines when take measures to eliminate overload. Based on the analysis of traditional methods of eliminating overload lines, this paper proposes an new overload control scheme based on wide area information, which can in parallel analyzing the impact of the normal line´s redundancy on the regulated quantity of matching units, then the analysis results are sent to the control center, which finally determines the regulated quantity. It can ensure the normal lines won´t overload when eliminating overload, and also can improve the computing speed of the whole control process. Therefore, it´s very conducive to ensure the power system operating in a safe and stable state. Finally, simulation experiments verify the program is fast and reasonable.
