摘要
研究了常规潮流计算与最优潮流计算的理论和区别,利用电力系统分析综合程序(PSASP),以山西长治电网为例,进行潮流计算及静态安全分析。潮流计算的结果表明,发电功率与负荷需求基本达到供需平衡,各节点处的电压也符合要求;静态安全分析的结果表明,无故障断开某些线路时,将引起某些线路过载及电压降低,不能满足运行要求。通过对实际电网采用PSASP软件进行潮流计算及静态安全分析,证明PSASP能够较好地分析实际电网的潮流分布和负荷情况,能够满足电力系统运行分析与规划的数字仿真需要,从而保证电网的安全稳定运行。
A comprehensive investigation on the theory and the difference of the normal power flow and optimal power flow (0PF) is carried out in this paper. It processes power flow calculation and static state security analysis based on Shanxi Chang Zhi Power Grid in Power System Analysis Software Package (PSASP). The results of the power flow calculation show that output and load demand basically obtain the power supply and demand balance, the voltage of per node also accords with the request; the results of static state security analysis show that no fault cut some lines may cause over loading and lower voltage, which can't satisfy the demand of power grid. Through using the PSASP software to process power flow calculation and static state security analysis Of the actual power grid, it shows that PSASP can analyze the actual power grid's power flow distribution and the load situation well and satisfy the digital simulation needs which the electrical power system movement analyzes and plans, thus guarantee power grid's security steady operation.
