摘要
对负荷节点的临界状态进行了研究,提出了用有功裕度来反映节点承受负荷功率变化的能力,以此为依据,通过描绘各节点的P-V曲线得出各节点的临界功率,进而确定出无功补偿点。5节点算例表明了该方法的简单性、有效性。
The cirificality to the load point is studied. Propose to use aetive margin to reflect ability of the point which bears load power changes. As a basis for this reason, get the cirtical power of the points through describing point P - V curves, thus set reactive compensation points. 5 point example shows simplicity and availability of this method .
