The paper covers some case studies that provide detailed, realistic examples of how to use SimPowerSystems in power system analysis. The following types of studies are covered on the paper:1. Thyristor-Based Static Var Compensator. 2. Transient Stability of a Power System with SVC and PSS. 3. GTO-Based STATCOM: Study the steady-state and dynamic performance of a static synchronous compensator (STATCOM) on a transmission system. 4. Control of load flow using UPFC: Study the steady-state and dynamic performance of a unified power flow controller (UPFC). 5. Variable-frequency Induction Motor Drive: Study of a PWM inverter is used as a variable-voltage, variable-frequency source to drive an induction motor in variable-speed operation. 6. Chopper-Fed DC Motor Drive: Study of a DC motor drive with armature voltage controlled by a GTO thyristor chopper. 7. VSC-Based HVDC Link: Modeling of a forced-commutated voltage-sourced converter high-voltage direct current (VSC-HVDC) transmission link.
