Abstract

Low-frequency power oscillation issues are both serious in Yunnan power grid and Southern China power grid, the two "west to east" complex and long chain configuration networks. Based on the significant data provided by the real-time monitoring system in Yunnan power grid, low-frequency issue is analyzed by Prony method, frequency, amplitude, angle and the damping ratio of system are obtained. Analysis results provide suggestions to establish restraining measures for low frequency oscillation and operation control strategy to restrain low- frequency oscillation.
