Static Synchronous Compensator and Superconducting Fault Current Limiter for Power Transmission System Transient Stability Regulation Including Wind Generator

摘要

The increase of environmental pollution and the decreasing of the energy is extremely related to social progress. The resolution of the environment pollution depends on renewable energy such as wind energy system. Though, that system is required by transient and voltage stability issues with wind energy employing fixed-speed induction generators to be augmented with resistive type superconducting fault current limiter (SFCL) and dynamic compensation devices, such as a Static Synchronous Compensator units (STATCOM). The use of combined model based SFCL and STATCOM for promoting the transient and voltage stability of a multi-machine power system considering the fixed-speed induction generators is the primarily focus of this study. The proposed combined model functions top reserve simultaneously a flexible control of reactive power using STATCOM controller and to reduce fault current using superconducting technology based SFCL. The effectiveness of the proposed combined model is tested on the IEEE11-bus test system applied to the case of three-phase short circuit fault in one transmission line. A simulation results are presented in this document.
