Abstract

The invention discloses an energy collection and storage system and method based on a magnetic suspension flywheel. The system comprises a base, wherein a relay, a photoelectric gate circuit input end control system and a cylindrical shell are fixed to the base, six T-shaped electromagnets are symmetrically fixed outside the cylindrical shell, the upper portion and the lower portion in the cylindrical shell are respectively provided with a permanent magnetic suspension array, a reluctance motor rotor also serving as the flywheel is suspended in the middle in the cylindrical shell, and the reluctance motor rotor also serving as the flywheel is fixedly connected to a rotating shaft. Discontinuous and tanglesome-waveform electric energy generated by some environment-friendly power generation devices can be conveniently and stably collected and stored, the electric energy is stored in the magnetic suspension flywheel as mechanical energy, the requirement for the charging process is extremely low, there is no any limitation for the energy charging time, and the system and method are suitable for being popularized in the electric power industry on a large scale.

Description

technical field [0001] The invention relates to an energy storage system, in particular to an energy collection and storage system and method based on a magnetic levitation flywheel. Background technique [0002] Today's energy-saving and environmentally friendly power generation devices and power generation technologies, such as stepping power generation, thermoelectric power generation, and wind power generation, all have some common shortcomings, such as the small amount of energy generated and the process is intermittent, which is difficult to be collected, stored and utilized. [0003] The existing way of collecting and storing the electric energy generated by these energy-saving and environment-friendly power generation devices is to use electronic circuits to rectify and filter it, and then store it in the battery. The electric energy generated by the power generation device is intermittent and unstable, so it is very difficult to collect and process the electric ener...
