A simulation test device of a direct-drive ocean wave power generation system and its application method

Abstract

The invention relates to a simulation test device of a direct-drive wave power generation system and a using method of the direct-drive wave power generation system. The simulation test device comprises a mechanical part and an electronic control part. The mechanical part comprises a mechanical limit seat, two guide rails are fixed to the mechanical limit seat, a permanent magnet linear motor and a generator are arranged on the guide rails, and a grating ruler is arranged on any guide rail. The electronic control part comprises an upper computer, a motor control instruction, the location information of the permanent magnet linear motor and the voltage signals and the current signals of a DC-AC converter are all transmitted to a motor controller, the direct-current bus currents of the DC-AC converter are controlled to be inverted by the motor controller and are input into the permanent magnet linear motor, thrust is output, the permanent magnet linear motor is pushed to generate electric energy, and output three-phase alternating currents are transmitted to an AC-DC converter. The control strategy of the generator, the location information of the permanent magnet linear motor and the voltage signals and the current signals of the AC-DC converter are all transmitted to a generator controller, the three-phase alternating currents are controlled by the generator controller to output direct currents through the AC-DC converter, and power is supplied to loads.

Description

technical field [0001] The present invention relates to a simulation test device and its use method, in particular to a simulation test device of a direct drive ocean wave power generation system and its use method. Background technique [0002] The interaction of wind and sea surface produces waves, and wave energy is one of the water energy resources expressed in the form of kinetic energy. In 1977, someone calculated the waves of the world's oceans and believed that the global wave energy power is about 70 billion kilowatts, of which about 2.5 billion kilowatts can be developed and utilized, which is similar to tidal energy. There is such a wealth of energy in the waves, and converting the kinetic energy of the waves into electrical energy has been an ideal that people have dreamed of for many years. In order to meet the challenge of energy security, all countries are trying to find ways to increase income and reduce expenditure. Since the 1970s, many countries, such as...
