Fault ride-through refers to the capability of a wind turbine or other generation unit to remain connected to the grid and continue operating during a fault event, such as a voltage dip or short circuit, and then recover afterwards. Option

Reactive power compensation is a technique used to manage the flow of reactive power in a power system, mainly to maintain voltage stability and meet voltage requirements at specific points. Option A refers to voltage stability or power flo

Synchronization is the process of connecting an AC generator to an AC power system and adjusting its speed, voltage, and frequency so that it matches the system parameters and operates in synchronism with it. Option B describes the adjustme
