Capacitor-Bank Reactors: These reactors are used in combination with capacitor banks for power factor correction. They help control the flow of reactive power and maintain a desired power factor in the system.
Conversely, capacitive reactors can lower the voltage by absorbing reactive power and reducing the voltage levels. Reactive Power Compensation: Power systems consist of both active power (real power) and reactive power.
A common thread to all installations is the question of what, if any series reactor should be installed with the capacitor bank. Series reactors are used with capacitor banks for two main reasons: Control the natural frequency of the capacitor bank and system impedance to avoid resonance or to sink harmonic current.
Inductive reactors can help to raise the voltage by introducing a voltage drop in the circuit, which can be useful in cases where the voltage is too high. Conversely, capacitive reactors can lower the voltage by absorbing reactive power and reducing the voltage levels.
Transient Stability: During sudden changes in the power system, such as faults or disturbances, reactors can help improve the transient stability of the system. By limiting the rate of change of current, reactors prevent rapid fluctuations that could destabilize the system. Harmonic Filtering: Reactors are sometimes used for harmonic filtering.
Shunt reactors are connected in parallel with capacitors to limit the overvoltage that can occur due to the resonance between the reactive power sources. They help maintain the stability of the system.
