| 摘 要： | 可控并补装置位置和容量的合理选择,有助于提高电网运行安全性和经济性。确定运行方式下节点电压对并联电纳的灵敏度指标,反映了有效并补位置,但非必要补偿位置。文中提出采用灵敏度和概率潮流算法,综合确定实际需要并补位置。根据随机故障后并联电纳的概率分布,确定固定和可控补偿容量比例。研究结果表明:根据并补电纳的区间概率分布,可确定可控并补容量及其满足电压控制目标的概率;补偿容量不仅受电网故障方式,也与并补装置电压设定值有关。

| Abstract: | It is helpful to improve the security and economics of power system with Static Var Compensators(SVCs)at suitable locations and in optimized capacities.Under given system condition,the sensitivity index of bus voltage to shunt susceptance indicates the effective compensation location instead of the necessary site.A new algorithm combining sensitivity and probabilistic load flow method is proposed to decide the SVC location.The fixed and controlled compensation capacities obtained with the probabilistic dist... |
