When there is a need to increase MVARS due to inductive reactive power demands, which equipment should be primarily used?

The primary equipment used to increase MVARS in response to inductive reactive power demands is capacitor banks. Capacitor banks are designed to supply reactive power, helping to counteract the effects of inductive loads that draw reactive power from the system. By adding capacitance to the electrical network, capacitor banks can effectively improve power factor and voltage stability, thereby enhancing the system's overall efficiency.

In systems where inductive loads, such as motors and transformers, are prevalent, the demand for reactive power can noticeably increase. Capacitor banks are implemented to provide the necessary MVARS to maintain the system's voltage levels and support the system's reactive power needs. This ultimately allows for more efficient operation of electrical equipment and reduces the risk of voltage drop.

Other equipment listed, like generators and transformer tap changers, serve different functions. Generators adjust the kV setpoint primarily for active power generation rather than reactive power compensation. Transformer tap changers modify voltage levels but do not directly address reactive power demands in the way capacitor banks do. Shunt reactors, on the other hand, are used to absorb excess reactive power, not to provide it, making them less suitable for increasing MVARS in response to inductive loads.
