Abstract

The invention discloses a wave power generation unit comprising a wave power collection mechanism, an energy conversion mechanism, a generator, a converter, and a control system. The wave power collection mechanism, the energy conversion mechanism, the generator and the converter are disposed on a platform and connected in sequence. The control system is connected with every one of the wave power collection mechanism, the energy conversion mechanism, the generator and the converter. The energy conversion mechanism is provided with a speed regulating valve inside. The current output end of the converter is connected with a power grid. The wave power generation unit is characterized in that the wave power collection mechanism converts wave power into mechanical energy and transmits the mechanical energy to the energy conversion mechanism; the energy conversion mechanism converts the mechanical energy into rotational mechanical energy driving the generator to generate powder; the current output from the generator is converted into current, the same as the voltage and frequency of the power grid, by the converter, and the current can be connected to the power grid directly; the control system acquires status signals of all steps of the wave power generation unit, can control the energy conversion mechanism, the generator and the converter in a coordinated manner so as to control output power, and ensures output electricity of the wave power generation unit is satisfactory.

Description

technical field [0001] The invention belongs to the technical field of power generation systems, and in particular relates to a wave energy power generation device. Background technique [0002] Wave energy power generation uses wave energy as the driving force to produce electric energy. Wave energy is a nearly unlimited energy resource. The use of wave energy power generation has brought power supply protection and great convenience to industrial and domestic electricity consumption. [0003] At present, the commonly used wave energy power generation technology is to use wave energy collection mechanism to collect wave energy, convert the energy generated by wave fluctuation into electric energy through energy conversion mechanism and generator, and connect the generator directly to the power grid or directly to the electrical load. The generated electric energy is directly connected to the grid or used. [0004] However, due to the intermittency and volatility of wave en...
