摘要
分析了常规潮流法在鞍结分岔点附近不收敛的原因 ,提出了一种利用改进的常规潮流法绘制完整 P-V曲线的新方法 ,很好地解决了常规潮流法在鞍结分岔点附近不收敛的问题 ,可顺利越过鼻形点 ,绘制出满意的 P-V曲线。该方法比连续潮流法计算更简单、更快速 ,实例证明了该方法的有效性。
The cause of the divergence of the conventional power flow method near the saddle node bifurcation was analyzed.A new method of plotting complete P-V curves using the improved conventional power flow method was presented and the problem of the divergence of the conventional power flow method was solved.Using this method the nose node can be crossed successfully and a complete P-V curve can be plotted,which is simpler and quicker than the continuous power flow method.The effectiveness of the method was proved by the actual sample
