Research on tie-line power fluctuation based on power transmission parallel
摘要
Abstract
In order to ensure the safety and stability of power system, this paper proposes a method to calculate tie-line power fluctuation in the process of paralleling based on power transmission. Paralleling process is divided into power transmission and closing process. During power transmission, tie-line power fluctuation depends on the reference power and control system performance. At the moment of closing tie-line circuit breaker, tie-line power fluctuation is considered as the fluctuation caused by power shortage in interconnected AC system, and power fluctuation peak can be calculated through second-order system step response overshoot, power fluctuation peak is mainly determined by the ratio of inertia constants of power systems on both sides and the damping ratio of area oscillation mode. PSCAD simulation results suggest that theoretical values are basically the same as simulation results, and this method can accurately describe the paralleling dynamic process.关键词
