摘要
大量风电机组接入电力系统将引起许多复杂的问题,因此,必须计算含有风电场的电力系统潮流。文章在简化的异步发电机稳态等效电路的基础上,提出了计算含风电场的电力系统潮流的联合迭代方法,通过修正雅克比矩阵以简化迭代过程解决了计算精度与迭代效率之间的矛盾。该方法既考虑了风电机组机端电压、有功功率、无功功率以及滑差之间的耦合关系,又大大缩短了潮流计算时间。计算结果表明了该方法具有一定的实用价值。
A number of complicated issues will be caused when a lot of wind turbines are connected into power system,so it is necessary to calculate the load flow of power system containing wind farms.Based on simplified steady-state equivalent circuit of asynchronous generator a joint iteration method to calculate load flow of power system containing wind farms is proposed.By means of modifying Jacobian matrix,the iteration process is simplified,thereby the conflict between calculation accuracy and iteration efficien...
