Development of intelligent design and simulation platform for medium voltage circuit breakers

Abstract

With the rapid development of electrical industry, the traditional design method of circuit breakers can not meet the requirement. In this paper, in order to accelerate the design period of medium voltage circuit breakers and improve the overall performance of them, an intelligent design and simulation platform has been developed. The software consists of four main modules: Module of evaluation and prototype selection, parameterized modeling module, simulation module, optimization module and output module. The three-dimensional models of some medium voltage circuit breakers have been parameterized with Pro/Engineer software and a library of the product models has been built. In module of evaluation and prototype selection, in the basis of fuzzy evaluation algorithm, a required circuit breaker model is selected from the built library according to design requirement. In the parameterized modeling module, the 3D model of them can be modified and reused. In the simulation module, through developing interface software connecting with ANSYS and ADAMS, electrical simulation, magnetic simulation, stress simulation and kinematic simulation of the medium voltage circuit breakers can be done in background. In the optimization module, the overall optimization of circuit breakers is done using the typical optimization algorithm. By the methods of modular design, the reuse of product models and design knowledge has been realized in the software.
