电气设备温度过高会导致电力系统稳定性下降,为了准确控制电气设备的温度,此提出电气设备温度的自适应模糊PID调试方法。从发电设备和供电设备两种角度确定电气设备热稳定限额,获取电气设备当前温度场信息。在模糊规则中添加电气设备热稳定限额,驱动自适应模糊PID按模糊规则及限额要求调试当前温度场信息。根据自适应模糊PID的输出结果,实现电气设备温度调试。实验结果表明,在对输电线路导体和外壳、以及对不同电气设备的温度调试时,所提方法的调试性能好。

At present,excessive temperature of electrical equipment may lead to the decline of the stability of the power system.In order to control the temperature of electrical equipment accurately,this article put forward an adaptive fuzzy PID debugging method for the temperature of electrical equipment.At first,we determined the thermal stability limit of electrical equipment from the perspective of power generation equipment and power supply equipment,thus obtaining the current temperature field of electrical equipment.Then,we added the thermal stability limits of electrical equipment to the fuzzy rules,thus driving the adaptive fuzzy PID to debug the current temperature field information according to the fuzzy rules and limits.According to the output of adaptive fuzzy PID,we achieved the temperature adjustment of electrical equipment.The experimental results show that the proposed method has good debugging performance in the temperature debugging of transmission line conductors and enclosures,as well as different electrical equipment.
