Water and Power Development Authority (WAPDA) Pakistan has lack of reactive power reserves. The station which needs reactive power to boost the voltage during under voltage problem also requires some source to absorb reactive power to overcome over voltage problem.
In this research work, the behavior of static Voltage control through STATCON has been reviewed and real data of WAPDA 500/220 kV power system regarding extreme cases of voltage control has been simulated on power system simulator PSS/E.
Different rating of simulated STATCON has been proposed at various locations to overcome voltage stability problem, increase steady state, dynamic state and transient stability.
Due to practical nature of the research work, it would be effectively utilized for resolving issues and bottlenecks related to WAPDA primary transmission line.
