How does a "shunt reactor" compensate for capacitive loads?
1 Answer
A shunt reactor is a device used in electrical power systems to compensate for capacitive loads, which are essentially reactive power sources caused by elements like transmission lines, cables, and other equipment with inherent capacitance. These capacitive loads can lead to an imbalance in the power system, affecting voltage levels and overall system stability. Shunt reactors are designed to counteract this imbalance by providing inductive reactive power, thus compensating for the capacitive reactive power.
Here's how a shunt reactor works to compensate for capacitive loads:
Inductive Reactance: A shunt reactor is essentially a coil of wire wound around a core, similar to a transformer winding. When connected in parallel (shunt) with the power system, the shunt reactor provides an inductive reactance. Inductive reactance opposes changes in current and helps absorb or supply reactive power, depending on the system's requirements.
Reactive Power Compensation: Capacitive loads in a power system lead to excess reactive power, which can result in overvoltage and voltage instability. By introducing shunt reactors, which provide in
