Abstract: Aiming at the problem that the traditional photovoltaic cells power was too low and unable to conventional drive flywheel high-speed by asynchronous motor, photovoltaic battery power rule, the principle and characteristic of flywheel energy storage system, operation characteristics of the motor were studied. A power control system was proposed based on the model track. Intensive sampling method was adopted to power samples provided by the photovoltaic cells, and used model to calculate the corresponding control parameters, combined with vector control method for motor power control; The objective of the power track achieved by the model that could be detected according to the change of the battery power input constant revision control parameter to form a dynamic control. In the Matlab / Simulink environment simulation model was established and analyzed. Research results indicate that the system can effectively track the input power, and motor can drive flywheel operate at a higher speeds, response fastly and have good control performance. It reaches control purposes, is feasibility and practicality.
