Reactors are typically inductive devices, and they enhance the performance, stability, and efficiency of the power grid. There are different types of reactors used in substations, and their applications vary based on the specific requirements of the power system.
Shunt reactors are connected in parallel with the transmission lines or power cables.
They are primarily used to compensate for capacitive reactive power in long transmission lines. This helps in voltage stabilization and reducing line charging currents.
Series reactors are connected in series with the transmission lines. They provide impedance to the flow of current and help in controlling the line charging current. Series reactors also enhance system stability and reduce short-circuit currents.
Neutral grounding reactors are connected to the neutral point of transformers.
