摘要
给出了各类PQ、PI与PV型DG的模型及在潮流计算中的处理方法,并改进了基于无功分摊原理确定PV型DG的无功初值及无功修正值的方法,同时给出了无功越界的处理方法。最后在MATLAB 7.8版本环境下,编写了含有分布式电源的配电网计算的程序,通过对算例的输出结果的分析,从而验证了本算法是可行有效的,同时DG的接入对电压的影响进行了分析,结果表明DG的接入会在一定程度上对电压有一定的支撑作用。
There are many DG model of And improved the determine DG the type PQ,PI,PV and the Processing method of PV model reactive initial value and of power flow calculation in this page, reactive a revised method based on Reactive apportion principle and give the treatment method of reactive power cross the border. Finally, In MATLAB 7.8 version environment, compile the distributed power distribution network calculation of containing the program, calculate two examples, Through analyzing the examples and the output of the results, Which has verified the algorithm is feasible and effective. At the same time analyzed the access to DG influence of the voltage, the results show that DG access has a certain supporting function to the voltage.
