Introduction

Electrical power systems are combinations of electrical circuits and electromechanical devices like motors and generators devices and sophisticated control system concepts that tax traditional analysis tools and techniques. Further complicating the analyst's role is the fact that the system is often so nonlinear that the only way to understand it is through simulation. Land-based power generation from hydroelectric, steam, or other devices is not the only use of power systems. A common attribute of these systems is their use of power electronics and control systems to achieve their performance objectives. Matlab SimPowerSystems[1] is a modern design tool that allows scientists and engineers to rapidly and easily build models that simulate power systems. It uses the Simulink environment, allowing you to build a model using simple click and drag procedures. SimPowerSystems toolbox is an efficient tool for modeling and simulating power system with FACTS devices and power converters. SimPowerSystems also is an efficient tool for modeling the dynamics of power system including all types of machines and controllers, i.e. modeling synchronous machines with governor, exciter and AVR, power system stabilizer, asynchronous machines, High Voltage DC Links (HVDC), DC motors and various speed controllers for DC and AC drives using power electronics converters. Reference [3] is one of the best references in studying multimachine system dynamics and stability. Reference [4] includes analysis of the properties of semiconductor devices and their applications as controlled rectifiers, inverters, cycloconverters, choppers, HVDC and solid state control of DC and AC motor. Reference [2], [5] include an overview of the principles of work of most FACTS devices.

The paper covers some case studies that provide detailed, realistic examples of how to use SimPowerSystems in modeling power system dynamics in various types of application that use power electronics converters. The following case studies are simulated on the paper:

1- Thyristor-Based Static Var Compensator.

2. Transient Stability of a Power System with SVC and PSS.

3. GTO-Based STATCOM.

4. Control of load flow using UPFC.

5- Control of AC motor.

6- Control of DC motor.

7- VSC-Based HVDC Link.
