At first, the authors make the model of the autotransformer, conclude the math equation, and get the reason that when the power flows simultaneously from the HV side and the LV side to the IV one, and when the common winding reaches its rating value, the power from the HV winding...

The article describes the question why the HV winding or the IV winding of the autotransformer is below rating burden while the common one is over burden in some case, and how to make the autotransformer transfer as much power as it can. At first, the authors make the model of the autotransformer, conclude the math equation, and get the reason that when the power flows simultaneously from the HV side and the LV side to the IV one, and when the common winding reaches its rating value, the power from the HV winding and the IV winding cant get to their rating value. Secondly, the result above is validated through a detail calculation to a transformer of a substation, and the way to make the autotransformer transfer more power is put forward, i.e. improving the power factor and reducing the reactive power from the LV side to the IV side.

自耦变压器在某种运行方式下,高压侧和中压侧还未到达额定容量,而公共绕组就已过负荷告警。对此,就为什么会出现上述情况以及如何改善运行方式才能使得主变压器尽可能满载运行进行了研究。首先通过对自耦变压器进行建模分析,推导出数学方程式,根据不同的运行方式进行分析,得出问题的原因,即自耦变压器在高压侧和低压侧同时向中压侧输送功率时,当公共绕组到达额定功率,高压侧和中压侧输送功率不能达到满功率输出。然后,对一个具体变电站的实际运行数据进行计算,验证了理论分析的结果,并提出了使自耦变压器尽可能地满负荷运行的方法:一要提高功率因数,二要减少由低压侧向中压侧输送的无功功率。
