Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] like figure 1 , figure 2 Shown is an ocean energy power generation monitoring device, including a generator and an electric energy processing module, a detection module and a remote control center; the remote control center communicates with the detection module through a GPRS network.

[0027] The generator and power processing module include a direct-drive ocean wave generator. The power output end of the direct-drive ocean wave generator is connected to the input end of the rectifier. Connect to the input end of the charger, the output end of the charger is connected to the input end of the battery through the relay 2, the output end of the battery is connected to the input end of the inverter / converter through the relay 3; the other way is connected to the drain through the relay 4. Discharge resistance; among them, relay 1, relay 2 and relay 3 are normal...

Abstract

The invention discloses a marine energy resource generation monitoring device. The marine energy resource generation monitoring device comprises a generator and electricity processing module and a detection module, wherein the generator and electricity processing module comprises a direct drive type sea wave generator, an electricity output end of the direct drive type sea wave generator is connected to an input end of a rectifier, an output end of the rectifier is divided to two paths, one path is connected to a charger through a relay I, the charger is connected to a storage battery through a relay 2, the storage battery is connected to an inverter / converter through a relay 3, and the other path is connected to a discharging resistor through a relay 4. The detection module comprises a voltage current signal sampling unit, a fault analysis processing module, a wave recording storage unit and a relay set control unit, and the electricity needed by the detection module is provided by the direct drive type sea wave generator. According to the marine energy resource generation monitoring device, when small faults occur, a wave recoding and feedback alarming method is adopted, and when large faults occur, a direct cutting-off loop, wave recording and alarming method is adopted, so that a control operator can judge the faults and deals with the faults according to the wave shapes of points of a system.

Description

technical field [0001] The invention relates to a new energy power generation and monitoring system, in particular to a power generation monitoring device using a linear ocean wave generator as an energy conversion device. Background technique [0002] The ocean occupies 70% of the earth's surface. It not only has abundant resources such as aquatic products, oil and natural gas, but also contains huge, clean, renewable and new marine energy. Ocean wave energy is ubiquitous in the ocean and relatively limited in time, while wave energy has the highest energy flow density and can provide considerable and cheap energy from smaller installations. [0003] At present, there are various forms of ocean wave power generation. The wave power generation device based on the rotary generator requires a gear shaft and other transmission devices, so its efficiency is greatly reduced, while the direct-drive linear generator can directly convert the ocean waves without any extra transmissio...
