Voltage Improvement Using STATCOM for Prototype Hardware Model, Using Synchronous and Induction Type Generator

As Availability of coal is decreasing day by day and the load demand is increasing very rapidly, the demand for setting new coal based conventional power plants have gone down. The other factors like availability of appropriate land, cost per MW generation, raw material availability, Pollution issues, etc are other constraints for developing new coal based plants. The present world wind power scenario with fast increasing installed capacity, crossing 63000 MW is adoption of new technological innovations based on proven latest acceptable designs. This has triggered the focus for setting more new non-conventional plants like wind, solar, biomass, etc. The wind generation has gained enough popularity due to advancement in the technology, availability of material, expert skilled labour, Installation cost, etc. Recently VSC based FACTS devices have been used for flexible power flow control, secure loading and damping of power system oscillations. Some of the FACTS devices are also used to improve the transient and dynamic performance of the system. The effect of different Loads, and voltage compensation using VSC based STATCOM is presented in this paper. During Compensation Voltage increases and load angle is maintained near unity, in some cases it is difficult to maintain the load angle near unity.
