摘要
在分析配电变压器损耗特点及负荷变化规律的基础上,提出了一种并列运行配电变压器(也称子母变)经济运行的实用方法,并设计出具有负荷统计与预测功能、可进行配电变压器经济运行决策的应用软件。该软件根据低压配电网负荷变化情况,分析配电变压器组的损耗,得出配电变压器组的经济运行区域,由此给出配电变压器经济运行建议方案,帮助用户进行决策,并通过实例验证了该软件的正确性和经济性。
The practical economic operation method of a kind of distribution transformers in parallel operation (also known as cluster variable) is proposed in the analysis of characteristics of distribution transformer loss and load variation. Application sottware with load statistics, prediction function and decision that can carry out economic operation of the distribution transformer is designed. Based on load change of low voltage distribution network, the loss of distribution transformer is analyzed by this software to receive economic operation area of distribution transformer. Economic operation scheme of distribution transformer is proposed to help customers to make decisions, and the correctness and economy of this software are proved by examples.
