Commutation Reactors

Commutation Reactors

Commutation reactors are electrical devices that are used to improve the performance and efficiency of high voltage direct current (HVDC) systems. They are also known as smoothing reactors or DC reactors. Commutation reactors are used to smooth the direct current waveform by reducing the ripple and harmonics that are present in the system. They are typically installed in series with the converter bridges in HVDC systems. The main function of commutation reactors is to limit the rate of change of current in the HVDC system. This is important because rapid changes in current can cause voltage spikes and other disturbances that can damage the equipment and reduce the efficiency of the system. Commutation reactors are designed to provide a smooth transition between the different phases of the HVDC system, which helps to reduce the stress on the equipment and improve the overall performance of the system. Commutation reactors are typically made from copper or aluminum windings that are wound around a magnetic core. The windings are designed to provide a specific level of inductance, which determines the amount of current that can flow through the reactor. The inductance of the reactor is also used to control the rate of change of current in the system. In summary, commutation reactors are essential components in HVDC systems that help to improve the performance and efficiency of the system. They are used to smooth the direct current waveform by reducing the ripple and harmonics that are present in the system. Commutation reactors are designed to limit the rate of change of current in the system, which helps to reduce the stress on the equipment and improve the overall performance of the system.
