基于matlab的双绕组变压器经济运行曲线绘制

Economic operation curve of double winding transformer based on matlab

变压器的损耗在电网损耗中占有相当大的比例。因此,实现变压器经济运行是降低网损、节约能源的有效手段之一。文章通过公式推导得到双绕组变压器经济运行方式的确定方法,并利用matlab软件编制变压器经济运行程序,该程序能绘制出双绕组变压器的经济运行曲线并划分出经济运行区域。通过两个实例验证了程序的有效性。

Transformer loss accounted for large proportion in power grid loss. Therefore, transformer economic operation is an effective way to reduce loss and save energy. The paper presents a method to check economic operation mode of double winding transformer by calculating. Moreover, using matlab transformer economic operation program has been workout. The program can draw economic operation curve of double winding transformer and point out economic operation area. The effectiveness of the program was testified by two tests.
