Optimisation of MSR & MSC switching instances during Auto mode operation of STATCOM to enhance the life of the equipment

The integration of STATCOM (Static Synchronous Compensator) technology into power grids has become essential for enhancing voltage stability, particularly in Low short-circuit levels (SCL) environments and Inter-regional grids. The primary function of STATCOM is to regulate reactive power injection and absorption during transient periods, thereby maintaining voltage within prescribed limits. To support dynamic compensation reserves during steadystate conditions, these systems are typically integrated with Mechanically Switched Reactors
