What is the Energy Storage Principle of a Flywheel?
1 Answers
1. During system energy storage, the motor operates as an electric motor, receiving electrical energy from the grid via a power electronic converter to accelerate the motor. The motor then drives the flywheel to accelerate and store energy, with the energy being stored as kinetic energy in the high-speed rotating flywheel. 2. When the flywheel reaches the preset maximum speed, the system enters an energy retention state. Upon receiving a control signal to release energy, the system discharges energy. The high-speed rotating flywheel utilizes its inertia to drive the motor to decelerate and generate electricity. The power converter then outputs electrical energy suitable for the load requirements, completing the conversion from kinetic energy to electrical energy.
