| description | The invention discloses a ZPW-2000 series track circuit compensation capacitance parameter estimation method and device, and relates to the technical field of railway signal equipment fault processing. The method comprises the steps that when compensation capacitance parameter estimation is carried out through induction voltage measured data of a locomotive, firstly, sample data are preprocessed, compensation capacitance parameters serve as decision variables, the difference between minimum induction voltage amplitude envelope actual data and induction voltage amplitude envelope theoretical data calculated based on a mathematical model serves as a target, a fitness function is constructed, a gray wolf optimization algorithm is adopted to iteratively search an optimal compensation capacitance parameter value according to the characteristics of insensitivity to an initial solution value, relatively high optimization efficiency, good global optimization performance and the like of the gray wolf optimization algo |
