Induction Motors (IMs) are now becoming the pillar of almost all motoringapplications related to industry and household. The practical applications IMs usually requireconstant motoring speed. As a result, different types control systems for IM's speed controlling havebeen shaped. One important techniques is utilization thyristor fed drive. Although, thethyristor induction motor drive (TFIMD) of...

In this Paper, complete models of three and six phase self commutated synchronous machine drives are presented, considering the effects of both time and space harmonics. First, the equations for calculation of machine inductances are developed. Next, "thyristor-inverter-electric machine" set is modeled in order to derive all the equations for conduction and commutation states. Finally, the resu...

Electrical circuits of reactive power compensation on the basis thyristor control in supply system oil refineries are considered. The main advantages, advantages over traditional systems and directions introduction into modern production formulated.

This paper deals with the simulation of eight bus system having fixed capacitor and thyristor controlled reactor. The system is modeled and simulated using MATLAB. The simulation results are presented. The power and control circuits are simulated. The current drawn by the TCR varies with the variation in the firing angle. The simulation results are compared with the theoretical results.

Contrary to traditional electrolysers which operate continuously at their nominal load, future alkaline need be able over a wide load range due the variability of renewable electricity supply. We have investigated how residual ripples from thyristor-based power supplies are influenced by operating system, and these affect efficiency electrolysers. For this, simulation tool was developed combine...
