配电网中变压器经济运行性研究

Economic Operation of Transformer in Distribution Network

由于配电网结构复杂,内含众多大容量变压器,配电变压器的经济运行对配电网的经济运行有重要影响。针对配电变压器效率低、功率损耗高的问题,基于变压器综合功率损耗理论分析和算例计算,从最佳负载系数、经济容量和经济运行区这3个方面对配电变压器的经济运行进行了研究。同时对配电变压器运行存在的管理问题,从制造、更新和技术这3个方面科学管理配电变压器经济运行。最终实现配电变压器经济运行,为未来配电变压器经济运行研究提供一定的参考。

Because of the complex structure of distribution network and the large capacity transformers, the economic operation of distribution transformers has an important impact on the economic operation of distribution network. In view of the problems of low efficiency and high power loss of distribution transformer, based on the theoretical analysis and calculation of comprehensive power loss of transformer, the economic operation of distribution transformer is studied from three aspects: optimal load coefficient, economic capacity and economic operation area. At the same time, the management problems existing in the operation of distribution transformers should be scientifically managed from three aspects: manufacture, renewal and technology. Finally, the economic operation of distribution transformer will be realized, which will provide some reference for the future research on the economic operation of distribution transformer.
