Embodiment 1

[0057] see figure 1 , the present embodiment provides a speed-increasing and steady-speed system for an ocean current power generation system, and the system is used in ocean current power generation equipment. The system can be directly used as an independent product, can also be an accessory of other ocean current power generation equipment, and can also be a system after updating the existing ocean current power generation equipment. The system can be directly installed in the ocean current environment to collect and transform the internal energy of the ocean current, and can also be used as an ocean current experimental equipment in an ocean current simulation environment. Even in some embodiments, the system can also be used as a current power generation in non-ocean waters The speed-increasing and steady-speed system of the device. Among them, the system mainly includes three parts, and these three parts are the turbo speed increasing device, the steady speed transmissi...

Embodiment 2

[0072] This embodiment provides a speed-increasing and stable-speed system for an ocean current power generation system, and the system adds some structures on the basis of Embodiment 1. Wherein, the steady-speed transmission device also includes a power generation statistics module, a torque sensor, and a rotational speed calculation module. The power generation statistics module is used to count the power generation Q of all generators 9 within a preset time T all , and calculate the generated power P of each generator 9, and In the formula, n is the number of generators 9. The torque sensor is used to detect the torque M of the generator 9 . The rotational speed calculation module is used to calculate the real-time rotational speed V. In this way, the speed can be obtained indirectly through the power generation and torque, and the real-time speed can be accurately calculated to ensure the accuracy of the speed calculation. Moreover, since the power generation is a com...

Embodiment 3

[0074] This embodiment provides a speed-increasing and stable-speed system for an ocean current power generation system, and the system adds some structures on the basis of Embodiment 1. Wherein, the steady-speed transmission device also includes a rotational speed detection module. The rotational speed detection module is used to detect the rotational speed of the slave gear 8 , which may use existing rotational speed detection equipment, or may be a rotational speed detection module embedded in the generator 9 . The speed information detected by the speed detection module can be transmitted to the hydraulic control center through wireless transmission, and the hydraulic control center controls the hydraulic pump 14 according to the information, so that the speed of the slave gear 8 can be adjusted, thus forming a closed-loop control structure. Keep the resulting voltage stable.

Description

technical field [0001] The present invention relates to a speed-increasing and stabilizing system in the technical field of ocean current power generation equipment, in particular to a speed-increasing and stabilizing system for ocean current power generation systems, and also to a method for increasing and stabilizing speed in ocean current power generation systems of the system. Background technique [0002] Ocean current power generation refers to a technology that uses ocean currents to generate electricity. In ocean movement, ocean currents play an important role in the earth's climate and ecological balance. Ocean currents move round and round along a certain route, and their scale is tens of thousands of times larger than that of large rivers on land. The flow of seawater can drive turbines to generate electricity and deliver green energy to people. China is also rich in ocean current energy, and the theoretical average power along ocean currents is 140 million kilo...
