摘　　要：为了提高混合式配电站变压器反应性负载的精准控制水平,提出了混合式配电站变压器反应性负载自适应控制技术。构建任意两个邻近电流间解耦公式,实现两个邻近电流之间的解耦。将负载电流的变化视为外界干扰,采用功率前馈控制方法,消除外界干扰对变压器的影响。通过补偿扰动负载电流,构建自适应增益函数,实现自适应增益的切换。使用K-means算法计算任意两个栅格的最小距离,分析混合式配电站变压器的负载状态。设计变压器反应性负载自适应控制逻辑,实现变压器反应性负载的自适应控制。由实验结果可知,该技术在12~18 ms内A、B、C三相负载电压曲线平滑,具有良好的控制效果。In order to improve the precise control of reactive load of hybrid distribution station transformers,an adaptive control technology for reactive load of hybrid distribution station transformers is proposed.Construct a decoupling formula between any two adjacent currents to achieve decoupling between two adjacent currents.Consider the change in load current as external interference and adopt power feedforward control method to eliminate the impact of external interference on the transformer.By compensating the disturbance load current and constructing an adaptive gain function,the switching of adaptive gain is achieved.Use the K-means algorithm to calculate the minimum distance between any two grids and analyze the load status of transformers in hybrid distribution stations.Design reactive load adaptive control logic for voltage transformers to achieve adaptive control of reactive loads in transformers.From the experimental results,it can be seen that this technology has a smooth voltage curve for A,B,and C three-phase loads within 12~18 ms,and has good control effects.
