Modeling of switched-reluctance drive in emergency operation

The authors have considered in MatLab Simulink the simulation model of one- and two-section switched reluctance drive operating in hazardous industrial mechanisms. The model allows investigating the work of switched-reluctance drive in usual, emergency and low-phases modes. The paper introduces a free-failure control algorithm which gives the possibility to provide the operation recovery of switched-reluctance drive based on continuous monitoring of phase currents and stirring up the operation recovery algorithm. The data of transient simulation at one motor phase loss in one- and two-section switched reluctance motors are given. The time charts are compared in rotation frequency of one- and two-section motor drives. The dependences of speed failure on drive structure switching time and load level are introduced. The paper introduces the adequacy of the proposed mathematical model which allows investigating the switched-reluctance drive.
