Simulation Studies of 3-Looped Speed Regulating System with an Internal Current-Change Loop

In this paper Simulation results of d. c reversible variablespeed system with an internal current-change loop, by means of general simulation program, are introduced. Safe commutation condition of the system has been proofed. On the basis of researchs about commutation procedure, it is demonstrated that this system possess constant interrupting current characteristic and gives a formulation for calculation. And finaly a function of setting signal filter will also be discussed.
