Abstract

ABSTRACT Distribution network experiences unbalancing due to random switching of loads, low voltage profile, high R/X ratio, and unequal loading in the different phases, which inturn causes more losses compared to transmission line. The voltage profiles, active, and reactive power in each phase are distinct due to unbalancing. In the present work, the authors analyzed unbalanced distribution network in presence of Series Voltage Regulator (SVR) considering the reduction in the losses and improvement in the voltage profile. The main highlights of the paper are: (i) placement and analysis of unbalance radial network with SVR at various phase angles; (ii) reduction in active, reactive power loss of the network and improvement in voltage profile; (iii) saving in cost of energy loss at different phase angle of SVR; and (iv) impact analysis of seasonal time varying load model. The placement of SVR at candidate node by considering real, reactive power loss reduction, and percentage rate of under voltage mitigated problem. Before and after SVR placements, the forward and backward sweep algorithm is used for the load flow calculation for analysis. The analysis is carried out on IEEE 25-bus radial distribution network with SVR phase shifter considering time varying seasonal load variations. Graphical Abstract

考虑时变负荷的SVR不平衡径向配电系统及移相器角度的影响分析

配电网由于负荷的随机切换、低电压分布、高R/X比以及不同相位负荷的不均匀而产生不平衡，从而造成比输电线路更大的损耗。由于不平衡，每一相的电压分布、有功功率和无功功率是不同的。在本文中，作者从降低损耗和改善电压分布的角度分析了存在串联稳压器(SVR)的不平衡配电网。本文的主要工作重点是:(1)用SVR对不同相位角的不平衡径向网络进行布置和分析;(ii)减少电网有功、无功功率损耗，改善电压分布;(3)节省了SVR在不同相角时的能量损失费用;(四)季节性时变负荷模型的影响分析。通过考虑实际、无功损耗减少和欠压率，在候选节点上放置SVR来缓解问题。在SVR放置前后，分别采用正向和反向扫描算法进行潮流计算分析。对考虑时变季节负荷变化的带SVR移相器的IEEE 25总线径向配电网进行了分析。图形抽象
