摘    要:以西北某地区电网为研究对象,在简化冲击负荷有功功率曲线的基础上,提出了一种简单易行且可与电力系统仿真软件BPA相结合的冲击负荷模型的建模方法。采用该方法仿真比较了不同类型冲击负荷对系统暂态稳定性的影响,验证了该方法的正确性和可行性,并对该地区电网2种最严重的故障情况进行了分析,提出了相应的安全控制措施。

关 键 词:电力系统  暂态稳定  冲击负荷  BPA  负荷模型

Abstract:Taking a certain regional power system in Northwest China for the object to be researched,on the basis of simplifying the active power curve of impact loads a simple and easy to implement modeling method for impact loads,which can integrated with BPA simulation software,is proposed. By use of the proposed method,the influences of different kinds of impact loads on transient stability of power system are simulated and compared,thus the correctness and feasibility of the proposed method are validated. In addition,two most severe fault conditions of this regional power system are analyzed by the proposed method and corresponding security control measures are put forward.
