developing V points and P points

The first consists in extending the PQV nodes and P node types in the currently available Newton-Raphson and PQ methods by adding the voltage of the controlling generator to the relative equations, and the reactive power of the generator can be obtained.

针对潮流计算中发电机及发电机群远方控制的情况给出2种不同的处理方法:一种是在传统的Newton-Raphson法及PQ法中扩展出PQV及P节点类型,将控制节点的电压作为状态量加入到方程中,从而控制发电机的无功出力;另一种是在传统潮流的基础上将被控制节点的无功不平衡量按负反馈的方式叠加到控制节点的无功方程中进行迭代修正,从而达到控制的目标值。
