Description

Intermittent energy power generation device

Technical Field

The utility model belongs to mechanical transmission, in particular to power generation facility that carries out the moment coupling with the intermittent type nature energy and supply the electricity generation for continuous, stable energy output to carry out energy storage, release in step in the coupling process.

Background

At present, most of known natural energy, such as wind energy, wave energy, tidal energy and the like, is intermittent, fluctuating and random nonlinear energy, cannot be directly utilized, and needs to be converted into continuous, stable and controllable linear energy for utilization through an intermediate energy collecting and storing process.

The small wind-driven generator converts wind energy into electric energy through an impeller, a speed change mechanism and a generator, stores the electric energy into a storage battery, and modulates the electric energy into a 50Hz power frequency power supply through a direct current/alternating current inverter to supply the power supply to a terminal user.

The large and medium-sized wind driven generator mainly has two forms, one of which is that a fan impeller is of a fixed-pitch stall regulation type, belongs to a constant-speed machine type, generally uses a synchronous motor or a squirrel-cage asynchronous motor as a generator, and a wind turbine controlled by the fixed-pitch stall keeps the rotating speed of the generator at a constant value, so that the rotating frequency of a stator magnetic field after the wind turbine generator set is connected to the grid is equal to the frequency of a power grid, the variation range of a rotor and the impeller is small, and the efficiency of capturing wind energy is. Secondly, the fan impeller is of a variable speed and variable pitch type, a double-fed motor or a permanent magnet synchronous motor is generally adopted, the rotating speed of the impeller can change in a wider range along with the change of the wind speed by a method of combining a speed regulator and variable pitch control, and the optimal tip speed ratio is kept to operate, so that the energy capture efficiency is maximized. The electric energy generated by the generator is adjusted by the converter to be changed into electric energy with the same frequency, phase and amplitude as the power grid and transmitted to the power grid. In contrast, variable speed wind generators offer advantages, but increase the complexity of the control system and the cost of manufacture.

In the wave energy power generation process, the collected intermittent mechanical energy needs to be converted into pressure energy or gravitational potential energy through an energy storage facility and then used for power generation or seawater desalination and the like, and the energy storage facility has high investment, high construction difficulty and low energy utilization rate.

In order to overcome the defects in the natural energy utilization process, the utility model provides a coupling and storage device which can output intermittent, fluctuating and random nonlinear energy into continuous, stable and controllable linear energy to be output to a generator for power generation, electrolytic hydrogen production, seawater desalination and the like, so as to improve the utilization rate of the intermittent energy.
