An Oscillation Center Identification Method and Application in Electro-mechanic Transient Simulation
摘要
Abstract
China power grid has become one large scale interconnected network; the power system fault may cause inter-area power oscillation. It is usually necessary to identify the oscillation areas and the oscillation center in the power system simulation, based on which we can find the weak area and the control measure. In the electromechanical transient simulation, oscillation center automatically finding function can provide important information for the power system analysis and has great application value. According to the characteristics that the oscillation center voltage is the lowest, the paper studied the oscillation center computation method using the line voltage. Combined with network analysis method, the paper studied the oscillation center analysis method in the electromechanical simulation. The research result has been applied in PSD-BPA transient stability program. Based on the actual grid simulation and analysis, the paper uncoverd the dynamic change process and characteristics of the oscillation center, and how to identify power system weak areas and judge the stability state base on them. The analysis method can effectively find the oscillation center of actual systems and has important role in the power system simulation and other analysis method study.关键词
