Feasible series compensation applications using Magnetic Energy Recovery Switch (MERS)

Different series compensation applications by using the magnetic energy recovery switch are reviewed. The magnetic energy recovery switch is a variable series compensation device characterized by simple configuration and control as well as a large operating range. Three different applications areas are introduced; load control, generator power capability improvements and series compensation in transmission systems. Load control application seems promising for cases where control of the frequency is not a necessity, such as for fluorescent lamps. By using MERS in series with permanent magnet generators can the output power capability of the generator be increased. At the high power end, MERS is discussed for use as a series compensator in transmission systems, where the power flow can be controlled and increased. In summary, the paper suggests a wider use of series compensation in electrical systems.
