Abstract

The paper presents a fuzzy approach for evaluation of the power/energy losses in transformers from the electrical distribution networks considering three input variables: the loading factor, the voltage on low side, and the performance standard. These are modelled as linguistic variables and fuzzy numbers. The obtained results on a real distribution network have shown that the developed approach can be used as an alternative tool to estimate the power/energy losses in transformers in uncertainty conditions when there is few information about the network state and performance standard.

用模糊方法估计配电变压器的能量损耗
本文提出了一种考虑负荷系数、低侧电压和性能标准三个输入变量的配电网变压器功率/能量损耗模糊评价方法。这些被建模为语言变量和模糊数。在实际配电网上的计算结果表明,该方法可以作为一种替代工具,用于在电网状态和性能标准信息较少的不确定条件下估计变压器的功率/能量损耗。
