| The studies of the power system stability are always the important problem in the tradition power system.If the electrified wire netting is destroyed in stability,it does not only destroyed the electrified wire netting but also bring about gigantic economic losses and significant social influence.Therefore the safe stable operation in an electrified wire netting becomes the all-important link of the power system.In this paper,a simulation model is built based on the power grid of Lvliang District of Shanxi Province,and a series of simulation analysis is carried out by using the power system analysis program PSASP.The main contents are as follows:1.introduction of simulation software PSASP and its application in power system simulation,PSASP as the world's most popular analysis software of power system simulation software,compared with the other same type,advantage is to provide to the user a complete graphical environment for users to establish a circuit model and circuit simulation analysis.2.explain the basic theory of power system stability analysis,including the calculation and analysis of the content of power system stability,methods and measures to improve the stability of power system,the detailed analysis of the method and process of power system transient stability analysis,is carried out in mathematical modeling and simulation analysis of power grid in Shanxi area of Lvliang province were studied more deeply theoretical base.3.in Shanxi power grid in Lvliang area as the prototype,build the simulation system based on PSASP,and then calculated and analyzed the trend of the calculation and analysis of the basic research on the transient stability,parameters need to consider in the process of comparing different influences on the critical time of the analysis,and the Lvliang regional power grid reactive power the optimization calculation results show that to improve the voltage quality,reduce network loss,achieved good optimization effect. |
