Literature Review on Voltage stability phenomenon and Importance of FACTS Controllers In power system Environment
Now a days the use of stable, reliable, economical, secure and efficient electrical paper drastically increasing in many sectors but the generated power in not being supported as much as increasing demand. The voltage stability plays major role in power system environment to meet the required demand. In this paper presents the phenomena of voltage stability in power system in which it reviews various reasons for voltage instability, types of voltage stability, characteristic of voltage stability, voltage control methods in power system environment, factors affecting voltage instability and collapse, scenario of voltage collapse and characteristics of reactive compensating devices are primarily discussed. It also reviews overview of major FACTS controllers, types of FACTS controllers, applications of FACTS controllers and their use in power system environment are discussed briefly.
