摘要
鞍山电网主网潮流计算是以220 kV网架潮流为基础,结合各枢纽供电断面的潮流、电网监控D5000系统的遥测数据分析和调度员人工判断的计算方法。随着科学调度方法提升,自动化及保护装置设计更可靠,该方法暂时满足现阶段调度员对于系统潮流分析的需求。随着用电需求递增,鞍山电网规模持续扩大,该方法无法满足事故紧急状态和电网运行远期分析需求。根据鞍山电网实际情况和调度运行需求,设计基于PSASP系统的66 kV系统主网仿真模型,并在特殊方式下进行仿真,为调度员在电网正常运行及发生事故时提供快速便捷的分析依据。
The main power flow calculation of Anshan power grid is based on the power flow of 220 kV grid structure,combining with power flow interface,the telemetry data analysis of D5000 system and judgement of dispatchers.With the improvement of scientific dispatching and the reliable design of protection device,this method can temporarily meet the demand of dispatchers.However,with the increasing demand for electricity,the scale of Anshan power grid continues to expand.The method of power flow calculation can not meet the needs of emergency and long-term analysis of power grid operation.According to the actual situation of Anshan power grid and the demand of dispatching operation,the simulation model of the main network about 66 kV system based on PSASP is totally designed.The related simulation is carried out under the special operation mode,which provides a fast and convenient analysis basis for dispatchers in the normal operation or accident of power grid.
