摘要

提出了静态串联电压恢复器(SSVR)不平衡径向配电系统(RDS)负荷潮流的建模方法。为了结合这种方法,推导了一个精确的SSVR模型,用于负荷流计算。推导了SSVR的无功功率额定值以及将特定节点的电压补偿到期望值(1p.u)所需的无功功率注入方向,并对其进行了分析和数学讨论。以25个节点组成的配电系统为例,验证了该模型的有效性。确定了配电网中缓解欠压问题的最佳位置。结果表明,该模型适用于大型配电系统的SSVR。

Analysis of unbalanced radial distribution system with SSVR
This paper presents modeling of Static Series Voltage Restorer (SSVR) unbalanced radial distribution system (RDS) load flow. To incorporate this approach, an accurate model for SSVR is derived to use in load flow calculations. SSVR reactive power rating as well as direction of required reactive power injection to compensate voltage of a particular node to the desired value (1p.u) is derived, discussed analytically, and mathematically. The validity of the proposed model is examined for distribution systems consisting of 25 nodes.The best location or under voltage problem mitigation in the distribution network is determined. The results show the validity of the proposed model for SSVR in large distribution systems.
