摘　　要：电力设备运行热稳定控制效果不佳会导致电力设备运行安全性差,为此,该文对线路多变条件下电力设备热稳定实时控制问题进行研究。采集电力设备边缘数据;构建电力设备热稳定极限平衡函数,求解电力设备热稳定性影响参数;以负荷最小、开关数最少作为目标,建立热稳定实时控制目标函数,在满足线路多变条件的基础上,通过离散化对电力设备负荷变化曲线进行处理,完成线路多变条件下电力设备热稳定实时控制方法。结果表明,所提方法控制后电力设备的功率波动小、线路电流值小、钢芯温度和铝层温度低。The poor thermal stability control effect of power equipment operation leads to poor safety of power equipment operation.Therefore,this article studies the realtime control problem of thermal stability of power equipment under variable line conditions.Collect edge data of power equipment.Construct the thermal stability limit equilibrium function of power equipment and solve the parameters affecting the thermal stability of power equipment.Taking the minimum load,the minimum number of switches and the minimum load as the objective,the realtime control objective function of thermal stability is established.On the basis of meeting the requirements of multiple lines,the load change curve of power equipment is processed through discretization to complete the realtime control method of thermal stability of power equipment under the condition of multiple lines.The results show that the power fluctuation of the power equipment,the line current value,and the temperature of the steel core and aluminum layer are low after the proposed method is controlled.
