The flywheel energy storage converter achieves the charging/discharging target of the flywheel energy storage system by controlling the flywheel motor. The flywheel energy storage motor in a vacuum environment has the characteristics of high efficiency, high speed, high base frequency, constant power, etc. Therefore, the flywheel energy storage converter must have good speed regulation performance, high operating efficiency, high working base frequency, low harmonic content, fast dynamic response, and high reliability.
The flywheel energy storage converter mainly controls the flywheel energy storage system to operate in three working conditions: electric speed increase, power generation deceleration, and steady speed standby.
HJ-MC series flywheel energy storage converter can maximize the flywheel energy storage capacity, extend the service life of the equipment, and comply with the grid guidelines.
