摘要
建立了基于PSCAD的辅机变频调速系统及其负荷模型,并完成与BPA仿真平台的逻辑对接,实现了机电暂态和电磁暂态联合仿真系统,用于电网故障对发电厂厂用系统的影响的分析研究。通过电厂出线单相故障、三相故障的仿真分析,验证了仿真模型的准确性和工程应用价值。
This paper establishes the model of variable frequency speed-regulating system based on PSCAD for power plant auxiliary and its load model, and completes the logic interfacing with the BPA simulation platform.The joint simulation system of the electromechanical transient and electromagnetic transient is realized, which is used for the analysis and research of the influence of power grid fault on power plant system.By the simulated analysis of the single phase fault and three phase fault of power plant outgoing line, the accuracy and engineering application value of the simulation model are verified.
