中文摘要:

为了更加清晰、直观、简便地反映电力系统这一混杂系统在低频减载(UFLS)装置动作时的全过程,解决仿真过程中频率与切负荷动作判断逻辑部分之间的连接与协调问题,提高电力系统低频减载仿真分析效率,利用Matlab中的PSB工具箱和状态流(Stateflow)分别对三机系统和其低频减载动作逻辑判断模块进行建模。提出了将Matlab里的状态流应用于复杂电力系统低频减载仿真的方案,实现状态流在电力系统低频减载仿真中的应用,并针对算例进行仿真分析,结果证明了状态流在复杂电力系统低频减载仿真中应用的合理性与有效性。

英文摘要:

To show the whole process of the power system which is a hybrid system when it’s under-frequency load shedding(UFLS) device acts more clearly、intuitively and easily, solve the problem of the simulation process when linking and harmonizing the frequency and the judging part of the UFLS, improve the efficiency of the power system UFLS simulation and analysis,then use the Matlab/PSB and Stateflow to simulate the three-machine power system and the judging part of UFLS respectively. Propose a scheme that applying the Stateflow into the complex power system UFLS simulation, to achieve the application of the stateflow into the power system UFLS, and then use an example to simulate and analysis, the result proves that the application of the stateflow into complex power system UFLS is rational and effective.
