Abstract

The invention relates to a wave energy electricity generation hydraulic PTO system comprehensive experiment platform and an experiment method thereof. The comprehensive experiment platform comprises a wave energy electricity generation hydraulic PTO system, a wave reciprocating motion simulation system, a monitoring system, a data collection system and a switching element. The comprehensive experiment platform can simulate the complex double-stroke motion of pistons of single-acting single-bar hydraulic cylinders of a transmission mechanism under the different sea conditions, simulate the different operation conditions of a PTO system and perform the system energy experiment and the key component feature experiment.

Description

technical field [0001] The invention belongs to the field of wave power generation, and in particular relates to a comprehensive experiment platform for a hydraulic PTO system of wave power generation and an experiment method thereof. Background technique [0002] In the field of wave power generation, the energy conversion system of the wave power generation device consists of an energy harvesting system and a PTO system. The energy harvesting system captures wave energy and converts wave energy into mechanical energy, and the PTO system converts mechanical energy into stable electrical energy output. The current PTO system mostly adopts the hydraulic type. The wave power generation hydraulic PTO system generally includes hydraulic cylinders, hydraulic motors, generators, hydraulic oil circuits and various hydraulic components for energy storage, reversing, speed regulation and pressure relief. The hydraulic motor is connected to the main shaft of the generator. The energy ...
