| 摘 要： | 提出了一种根据负荷电流计算变压器绕组平均温度的实时算法,该算法涉及了负荷电流的整个历史过程和环境温度的变化。通过监控绕组温升,从而使得变压器能够最大限度地发挥其过载潜力同时又保证必要的寿命。在假定的未来负荷和油温的条件下,该算法还能预报未来时刻的绕组温升/时间特性和绕组达到最高允许温度的时间。

| Abstract: | The paper presents an on-line algorithm for predicting the average temperature of power transformer winding according to its load current. The algorithm has accounted for the whole history of load current and variations of ambient temperature. The overload capabilities of transformer can be increased by monitoring and controlling the winding temperature and the necessary durability of the transformer can be ensured. The algorithm can also forecast the future winding temperature and the time of reaching the max, permitted the assumed future load current and oil temperature. |
