Abstract

The invention discloses a combined wave power generation device provided with oscillating buoys as well as a measurement and control system of the device. The power generation device and the measurement and control system are included, multiple groups of hiding platforms can be arranged according to the installed capacity, and multiple oscillating buoys are mounted on each hiding platform. On the basis of a traditional wave power generation device provided with oscillating buoys, a hydraulic energy storage system, a tide level adaptation system and a wave detection system are designed. The hydraulic energy storage system controls energy storage and energy release of energy accumulators to drive a power generator to generate power according to the upper limit and the lower limit of energy storage pressure of an energy accumulator group in combination with real-time wave information. According to the device, multi-point energy absorption replaces traditional single-point energy absorption, immediately captured wave energy can be maximized, the measurement and control system can cooperate with the combined wave power generation device provided with the oscillating buoys, multiple defects of shorter wave period, small wave height and low energy flux density of national offshore wave energy resources can be effectively overcome, and maximum-efficiency conversion of wave energy to power and maximum-efficiency utilization of the power are realized.

Description

technical field [0001] The invention belongs to the technical field of wave energy power generation, and relates to an oscillating buoy wave energy power generation system, as well as a measurement and control system and a measurement and control method thereof. Background technique [0002] Energy has always been an important issue related to my country's economic development. Most of all, after maintaining high-speed growth for many years, my country's economy has gradually entered a stage of slowing economic growth, but the demand for energy has been increasing, especially in the supply and demand of fossil energy (coal, oil, natural gas, etc.) , has not been able to reach a state of supply and demand balance, which has led to serious overcapacity in some industries (such as the coal industry), while supply in some industries (such as the oil industry) is less than demand. A major measure to resolve the contradiction between supply and demand of traditional fossil energy ...
