摘要

摘要: 铁损、铜损是影响配电变压器效率的基本损耗，尤其当三相负荷不平衡发生时还会带来附加损耗。为实现配电变压器效率最大化，结合低压供配电系统三相幅值和功率因数均不平衡的现状，通过数学建模对影响配电变压器效率的因素进行理论分析，并建立三相负荷不平衡度与配电变压器效率关系的度量式，基于联合机制提出实现配电变压器效率最大化算法。通过算例与实验法对所提理论进行验证分析，结果表明，通过治理中性线电流可以有效提高配电变压器效率。结合实验结果提出了实现配电变压器效率最大化的改良措施。

Abstract: Iron loss and copper loss are basic losses that affect the efficiency of distribution transformers,especially the occurrence of three-phase load unbalance can also bring additional losses. In order to maximize the efficiency of distribution transformers, combined with the current unbalanced situations of three-phase amplitude and power factors in low-voltage power supply and distribution systems,theoretical analysis is conducted on the factors affecting the efficiency of distribution transformers through mathematical modeling. The measurement formula for the relationship between three-phase load unbalance and distribution transformer efficiency is established, and an algorithm based on joint mechanism for maximizing distribution transformer efficiency is proposed. The proposed theory is verified and analyzed through numerical examples and experimental methods, and the results show that the efficiency of distribution transformers can be effectively improved by controlling the neutral line current. Based on the experimental results, improvement measures have been proposed to maximize the efficiency of distribution transformers
