摘要(Abstract)：

针对高中压侧并列、低压侧分列运行的220kV变电所的无功调压设备,提出了互调压系数的概念和数学模型,得出了计算公式。指出无功电压自动控制(VQC)策略上的缺陷,并以杭州电网某220kV变电所为算例进行了计算,验证了该模型和计算结果的正确。
For high-mid voltage parallel and low voltage unparallel operating mode of voltage regulating equipment in 220 kV transformer substation,we propose a concept and model of voltage regulating coefficient,and give the calculating formulation.And then,we point out the fault of VQC's strategy.At last,Numerical algorithms are described,one 220 kV transformer substation in Hangzhou power system is utilized to evaluate the proposed model and the results show that it is right.
