摘　　要：针对传统方法控制误差大的问题,提出交流接触器零电流分断智能控制方法研究。考虑交流接触器零电流分断具有非线性特征,利用人工神经网络对分段数据进行大量训练,拟合出零电流分断电势变化曲线,建立数学模型,预测模拟出交流接触器零电流分断动态过程,通过数学模型计算出交流接触器零电流分断时间,通过控制交流接触器首开相经过零电流的时间,实现此次研究目标。经实验验证,此次提出的方法具有较低的控制误差,可以取得良好的控制效果。Aiming at the problem of large control error of the traditional method,the research on the intelligent control method of zero-current breaking of AC contactors is proposed. Considering the non-linear characteristics of AC contactor zero current breaking,using artificial neural network to train a large amount of segmented data,fitting the zero current breaking potential change curve,establishing a mathematical model,predicting and simulating the dynamic process of AC contactor zero current breaking,The zero-current breaking time of the AC contactor was calculated by a mathematical model,and the research goal was achieved by controlling the time during which the first phase of the AC contactor passed zero current. The experimental verification shows that the proposed method has lower control error and can achieve good control effect.
