摘　　要：变压器是变电所中主要的耗能设备,变压器经济运行目的是减少变压器在运行过程中的有功功率损耗和提高其经济运行效率。变压器的经济运行是在确保变压器安全运行和保证电能质量的基础上,对变电所内变压器的参数规格进行理论分析和计算,通过Matlab仿真,画出负载损耗曲线并求解曲线之间的交点,确定变压器的经济运行方式。计算出不同运行方式下每台变压器的负载系数,在临界点求出变压器的经济运行区间,进而实现变压器的经济运行,降低变压器在网络中的电能损耗,节约电能资源。As the main energy-consuming equipment in the substation,the economic operation of the transformer is to reduce the active power loss of the transformer during the running process and improve its economic efficiency. On the basis of ensuring the safe operation of the transformer and the quality of the power,the load loss curve is drawn and the intersection between the curves which is drawn to determine the economic operation mode of the transformer through the theoretical analysis and calculation of the parameters of the transformer in the substation and Matlab simulation. The load coefficient of each transformer is calculated under different operating modes and the economic operation range of the transformer is found at the critical point to realize the economic operation of the transformer,reduce the power loss of the transformer in the network and save the energy resources.
