Speed Control System of Induction Motor by using Vector Control Method ijtsrd
In the Vector Control method of induction motors, one of the advantages of the separately excited DC motor of being able to decouple the flux control and the torque is thereby opened up. The field orientation control of induction motor allows decoupling the control of magnetic flux and the control of the torque produced by […]
Speed Control System of Induction Motor by using Direct Torque Control Method used in Escalator ijtsrd
Escalator is useful and act in the important part to carry passengers to the targeted floors of building. Every escalator must be driven by its own motor and this motor speed must be controled. To drive escalator with a constant speed, direct torque control technique is used to drive three phase squirrel cage induction motor. […]
Nonlinear Control of Static Synchronous Compensator STATCOM for Transmission System ijtsrd
The Static Synchronous Compensator STATCOM is a shunt controller, which is a member of FACTS devices. In this paper, an effective and robust controller for STATCOM device on transmission lines, a Single Machine Infinite Bus SMIB system is modeled. A state space mathematical model is constructed which considers both electromechanical oscillations and reactive current of […]
Differential Protection of Power Transformer in Substation ijtsrd
Protection scheme required for the protection of power system components against abnormal conditions such as faults etc., and that essentially consists of protective relaying and circuit breaker. Protective relay senses the fault and determines the location of fault. Then, protective relay sends the tripping command to the circuit breaker. Therefore, proper care should be taken […]
Simulation of 3 Phase, 24 Pulse GTO Converter for Flow Control of Transmission System ijtsrd
Gate Turn off GTO thyristor based power control controller for flow control of transmission system is used to regulate voltage and reactive power improment. GTO thyristor switching devices with high power handling capability and the advancement of the other type of power semiconductor devices such as IGBTs, MOSFETs, Ideal switch and so on have led […]
