电力系统仿真软件PSASP的在线应用

Online Application of Power System Analysis Software Package(PSASP)

通过对电力系统分析综合程序(PSASP)作业数据库结构、软件架构以及PSASP运行机制的剖析,开发了能访问其作业数据库的数据接口和调用其计算功能模块的计算接口。利用该数据接口,可将状态估计后的电网数据采集与监视控制系统(SCADA)数据导入到PSASP作业数据库中,并根据需求,利用其计算接口调用PSASP的不同功能模块,对实时电网数据进行处理。在此基础上开发了PSASP在线应用(通用)技术,克服了PSASP只能进行离线分析以及现有的在线分析软件存在用户面过窄的问题,该技术已成功应用于某地区实际电网的调度辅助决策软件开发中,为用户挖掘PSASP的计算功能及进行软件二次开发提供了新的思路。

At present, power system analysis software package （PSASP） has only offline applications because some problems existing in online software have not been solved yet. Therefore, the structure of database, construction of software and operational mechanism of PSASP were analyzed and interfaces for accessing database and calling calculation modules were developed, through which the SCADA ＇ s data can be imported into PSASP＇ s databases after the system status assessment. Moreover, the real-time data of power network can be processed by calling different functional modules through PSASP interfaces according to the requirements. By the application to an assistant decision-making system of a practical power system, it is shown that the proposed technology can provide a new thinking for PSASP users to extend its computing ability further.
