Control system asynchronous electric traction drive
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 6
Abstract
The analysis of solutions of problem of rational use of the asynchronous engine parameters as a part of asynchronous electric traction drive is carried out in the paper. The options of development of the optimized asynchronous engine control systems are considered and their main shortcomings are also revealed. The purpose of this paper is development of the optimized system of the asynchronous electric drive control that will allow reduction of losses in the course of electromagnetic conversion of energy in the asynchronous tractive engine. The result of synthesis of vectorial control system optimized by criterion of a maximum of electromagnetic moment in case of the specified current of the stator of the asynchronous tractive engine is presented. The distribution function of optimum angle of current vector position of the stator in relation to vector of current linkage of a rotor of the asynchronous engine is shown. For checking the obtained control system, the imitating model in the software environment MATLAB is developed. Results of modeling of the asynchronous traction electric drive operation on the basis of the asynchronous tractive engine AD-906 are given in the mode of acceleration and electrodynamic braking in case of different values of power delivered
