摘　　要：无论是配电网路线结构设计还是网点布置中,均存在电能损耗率较大的问题。为降低配电网的电能损耗并持续提升电能质量,提出基于自动电压控制(AVC)技术的配电网群控型台区功率主动调节方法。以配电网线路运行的等效负载为基础,对配电网群控型台区不平衡功率分量进行定义;按照负序分量和正序分量进行划分,选择动态指令对应运行模式,在不同的微分增益条件下确定配电网群控型台区功率调节函数;根据调节函数以及不同参数的所属范围,基于AVC技术确定调节模式,对配电网群控型台区不平衡功率进行主动调节。以配电网中的多个公用台区作为测试对象,通过调节各组台区的无功补偿容量,补偿容量最大可达580 kVA。实验结果表明该方法可实现功率容量的主动调节,使其满足配电网线路的运行标准,具有应用价值。The problem of large power loss rate exists both in the design of distribution network route structure and in the layout of outlets.In order to reduce the power loss of the distribution network and continuously improve its power quality,the active power adjustment method of distribution network group-controlled station area based on Automatic Voltage Control(AVC)technology is studied.Based on the equivalent load of distribution network line operation,the unbalanced power component of distribution network group-controlled station area is defined;the negative sequence component and positive sequence component are divided according to the dynamic command corresponding to the operation mode,and the power regulation function of distribution network group-controlled station area is determined under different differential gain conditions;according to the regulation function and the ranges of the different parameters,the regulation mode is determined based on the AVC technology,and the power quality of distribution network group-controlled station area is improved by AVC technology.According to the regulation function and the range of different parameters,the regulation mode is determined based on AVC technology to actively regulate the unbalanced power of distribution network group-controlled stations,and the method design is completed.Taking several public stations in the distribution network as the test object,and by adjusting the reactive power compensation capacity of each group of stations,the compensation capacity can reach up to 580 kVA.It indicates that the proposed method can realize the active regulation of the power capacity,meeting the operational standards of distribution network lines and demonstrating practical application value.
