The doubly-fed generators (DFIG) have clear superiority for the applications of large capacity and limited-range speed control case due to the partially rated inverter, lower cost and high reliability. These characteristics enable the doubly-fed wound rotor induction machine to have vast applications in wind-driven generation.In this paper Combined Vector and direct power control (CVDPC) strate...

The aim of this paper is to review the origin and developments of direct torque control (DTC), an advanced control technique of induction motor drives yielding superior performance. The direct torque control is one of the excellent control strategies available for torque control of induction machine. It is considered as an alternative to field oriented control (FOC) technique. The DTC is charac...

This study starts from the proof of Low Frequency Oscillation (LFO) and then points out that there are many ways to study the LFO including its rejection measures. Also in this study one control system is planned in order to regulate voltage at common coupling point (PCC) in where STATCOM is installed. This research present a single-machine infinite-bus system with one static synchronous compen...

introduction: radiation imaging is one of the applicable methods in diagnostic medicine and nondestructive testing for industrial applications. in nondestructive 3d imaging, in addition to the radiation source, there is a requirement for a suitable detection system, data acquisition system, mechanical sections for moving objects, reconstruction algorithm and finally a computer for processing an...
