摘　　要：以双端供电网变电所经济运行的电路模型为基础,用数学极值方法进行了双端供电网线路的微分分析和变电所主变经济运行方式分析,得出主变压器最小损耗和最大传输效率的表达式。通过算例说明了主变经济运行的最小损耗、主变经济运行的最大效率、主变实际运行损耗、主变实际运行效率的计算方法,可对双端供电网变电所主变压器的经济运行进行理论指导。The paper,on the basis of a circuit mode,analyzes the differential of double-side power supply network and the economic operation mode of main transformer by mathematical extremum method,and proposes the expressions of the minimum loss and the maximum transmission efficiency of the main transformer.Furthermore,it also presents a method for calculating the minimum loss and the maximum efficiency of the main transformer under the economic operation mode and that for computing the actual loss and efficiency of the main transformer,which can be well referenced by similar projects.
