变压器经济运行区间的确定与应用

依据变压器经济运行区间确定原则GB/T 13462-1992,推导并确定了变压器经济运行区间,将其划分出不良经济运行区间和最佳经济运行区间,首次明确给出了变压器最佳经济运行区间。以Microsoft Visio 2003为平台,编制了变压器经济运行区间图生成软件。利用该软件,建立了变压器经济运行区间模型。通过算例分析可以很直观的得出：当变压器在本文给出的最佳运行区间运行时,在降低损耗的同时,又充分提高变了变压器容量的利用率,保证了供电的安全可靠,为变电运行人员在变压器实际运行操作中提供了良好的决策依据。

Determination and application of transformer economic operation zone

According to the definite principle of economic operation zone of transformer that GB/T13462—92 ,economic operation zone of transformer is deduced and calculated and is divided undesirability and optimum.Optimum transformer economic operation zone is firstly determined.Gerative software is procedured that drawing of transformer economic operation zone according to the Microsoft Visio2003.The model transformer economic operation zone is established by maked use of the gerative software.It is arrived by according to the example in the article that wastage of transformer would be reduced and utilization ratio of capacity transformer would be raised when transformer is in optimum economic operation zone provided in the article.That ensure safety of power supply.This provided the decision-making basis for substation operation personnel under the pratical operation.
