A static synchronous compensator (STATCOM), originally known as a static synchronous condenser (STATCON), is a regulating device shunt-connected to alternating current electricity The choice of the The short circuit has the most serious influence on the voltage, and the voltage drop is 0.9. But the similarity ends there. A static var compensator can also be used for voltage stability. However, a STATCOM has better characteristics than an SVC. When the system voltage drops sufficiently to force the STATCOM output current to its ceiling, its maximum reactive output current will not be affected by the voltage magnitude. With regard to the maximum transient capacitive current it is observed that in an SVC the capacitive current is limited by the size of the capacitor and by the magnitude of the AC voltage. CONCLUSIONS We have examined the performance of SVCs and STATCOMs in electric power systems. Based on the analytical and simulation studies, the impact of SVCs and STATCOMs on the studied power system is presented. It was shown that both devices significantly improve the transient voltage behavior of power systems.
