SPEED CONTROL OF SYNCHRONOUS MOTOR BY USING VARIABLE FREQUENCY DRIVES

ABSTRACT :

A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resistance drop and slip frequency. The scheme proposed fully compensates for ....etc

ADAPTIVE AND NON-LINEAR EXCITATION CONTROL OF SYNCHRONOUS GENERATOR S STABILITY THROUGH NEURAL NETWORK

ABSTRACT
Adaptive and non linear Excitation control of synchronous generator s stability through Neural Network Control equipment of synchronous generators such as automatic voltage regulators, speed governors and power system stabilizers have been developed to maintain stability and to improve damping of the power systems. When an operating condition changes greatly, however, such controllers may become less effective bec ....etc

Abstract:
During a long time, permanent magnet synchronous motor (PMSM) were only reserved for some
specific applications, however, recently, these machines are becoming more used due to the powerful magnetic
characteristic of the rare earth, being used in different areas. Recently several researchers have proposed
implementations combining the use of permanent magnet synchronous motor with the direct torque control (DTC)
technique offering a quick and precise control. The present work combines these techniques and it proposes the ....etc

SYNCHRONOUS MOTORS



Synchronous Motors Steady-state Operation

for field current less than value related to IA,min armature current is lagging, consuming reactive power, while when field current is greater than value related to IA,min armature current is leading, and supplying Q to power system

Therefore, by adjusting the field current, reactive power supplied to (or consumed by) power system can be controlled
