Shunt Reactor

A shunt reactor is an electrical device used in power systems to absorb reactive power (inductive VARs) and improve voltage stability, especially on long high-voltage transmission lines. What it does: Reactive Power Compensation: Transmission lines generate reactive power due to their capacitance, especially when lightly loaded. This can lead to voltage rise at the receiving end. A shunt reactor absorbs this excess reactive power to prevent overvoltage. Voltage Control: Helps in keeping voltage within acceptable limits during low load or no-load conditions. Where it's used: Long high-voltage AC transmission lines (220 kV and above) Substations to manage voltage profiles Offshore wind farms or HVDC systems for stability and compensation How it works: Connected in parallel (shunt) to the transmission line or bus. Acts like an inductor, drawing inductive reactive power. Usually air-core or iron-core types depending on size and application. Types: Fixed shunt reactors always connected Switchable shunt reactors can be switched in/out depending on load Variable shunt reactors (VSRs) allow fine-tuned compensation via tap changers Would you like a diagram or want to go deeper into its design, applications, or how it compares to a capacitor bank or series reactor? You said:shunt reactor for low voltagesChatGPT said: Great question shunt reactors are mostly associated with high-voltage transmission, but they can be used at low voltages too, just in different contexts and forms. Shunt Reactors at Low Voltage (LV) Overview For low-voltage systems (typically under 1 kV), shunt reactors aren t as common, but similar principles apply when dealing with power quality and reactive power compensation. Typical Use Cases for Low Voltage Shunt Reactors: Neutral grounding reactors in transformer star-point grounding. Power factor correction tuning sometimes inductors are used to counteract over-compensation by capacitor banks (common in LV industrial setups). Harmonic filtering reactors (chokes) are added in parallel or series with capacitors to filter specific harmonics. Motor starting/reactive compensation in some motor control centers. Forms of Low-Voltage Shunt Reactors: Line reactors / choke coils: Often installed in series with loads like motors, but they can be adapted in shunt setups. Detuned reactors: Used in power factor correction systems to avoid resonance with harmonics.

Shunt reactors are normally used to compensate capacitive VARs generated by high voltage transmissions lines during light loaded conditions to avoid overvoltage at the other end. Other applications of shunt reactors include the use with capacitors to balance the three phase currents when used for single phase load.
