The use of flywheel asynchronized compensators in a power system

The main properties of asynchronized compensators, including those with a flywheel on the shaft, are considered. Areas of application of electrical-machine flywheel energy stores are suggested. It is shown that asynchronized compensators with a long-term/short-term power ratio of 100/200 MW and a power exchange time of 15 – 30 sec can be used in power systems as a second-mobilization power standby to improve the quality of frequency regulation.
