Abstract:

以往基于灵敏度类算法的有功安全校正计算过多地集中在如何计算灵敏度方面,且机组或负荷的调整顺序仅取决于灵敏度大小,对同一功率注入节点对不同支路潮流影响的差别考虑较少。目前求调整量的方法有了新的进展,可采用灵敏度绝对值大小和反向配对方法依次求得调整量。本文在此基础上,提出一种基于交叉权重和反向等量配对的有功校正控制决策分析方法。针对某一越限支路,该方法能在选择有效控制节点时,参考该节点对剩余过载支路的灵敏度大小,优化选取配对节点或节点组合,这样在有效调节指定过载支路越限的同时,兼顾了其他过载支路的调节策略,避免了单一调节引起其他正常支路潮流越限的反复调节,实现了有功校正控制计算。
