摘要(Abstract)：

基于无功规划的相关技术标准,给出了高压配电网无功规划优化实用模型:目标为无功补偿净收益最大,约束涉及相关技术标准对无功补偿总容量、单组容量及其组数、电压、功率因数的要求。根据高压配电网的特点,通过供电分区减小优化计算的规模和复杂性,并综合考虑分布式电源、主变分接头、弱环网等因素的影响,提出了一种基于高压配电网供电分区的3阶段启发式优化方法:首先分别针对各相对独立的高压供电分区,以净收益由大到小的顺序逐次确定单节点无功补偿的初始单组容量及其组数;然后,考虑到相同供电分区内不同位置无功补偿的相互影响,对初始无功补偿方案采用迭代计算进行修正;最后在全局范围内,对修正方案采用交流潮流进行校验并作进一步的优化微调。经对实际系统的计算分析,表明所提方法计算快速稳定,适用于大规模高压配电系统的无功规划优化。
