计入电晕损耗的潮流模型及计算

A POWER FLOW MODEL AND COMPUTATION INCLUDING CORONA LOSS

在超高压电网，电晕损耗是一种复杂，但不容忽视的现象。文中利用已有的电晕研究成果，将电晕损耗作为有功负荷处理，从而首次将电晕损耗计入到潮流计算的数学模型之中，与传统的潮流计算方法相比，网络的特性和迭代格式完全一致，所增加的计算量微不足道。

Corona is a complex phenomenon and the loss caused by corona is not negligible in EHV power systems. According to the existed research studies on corona, this paper presents a power flow model which includes corona influnence to power flow and energy loss. The paper keeps the iterative process and main computational steps adopted in conventional method. The extra computational task for handing corona problem is insignificant, but the computed results are more consistent with actual conditions. The method shows good beheavior by testing on a real power system.
