Description

Fluid kinetic energy full-rotation-range power generation rate regulation and control method and power generation rate regulation and control device Technical Field The present invention relates to a fluid power generation device for converting fluid kinetic energy into electricity, and more particularly, to a fluid power generation device for providing an electric power generation system with an invention conversion capability adjusting function. Background River, ocean current, sea tide and wind are rich and continuous energy resources in nature, and along with the development of technology, many technical means for generating electricity by using the green, clean and pollution-free natural resources have appeared to benefit mankind. Taking wind energy power generation as an example, the power generation efficiency and the safety of the wind energy power generation system mainly depend on three control parts of the wind power generation system, namely a wind yaw part for adjusting the wind direction to improve the capture of wind kinetic energy, a pitch part for enabling the system to safely operate at the limit wind speed, and a cable untwisting part brought along with wind yaw. The wind direction-adjusting yaw system mainly comprises a yaw motor, a speed reducer, a transmission gear and a yaw brake, wherein the yaw motor, the speed reducer, the transmission gear and the yaw brake are used for capturing wind energy which is limited to the maximum extent all the time, quite harsher sharp noise and serious noise pollution are generated in the process of starting to brake. To avoid this, the system requires periodic reverse untwisting from the untwisting portion, which also produces intolerable harsh noise. The pitch mechanism in the wind power generation system is a mechanism for adjusting wind power generation efficiency, particularly running safety according to wind speed, and comprises a pitch motor, a speed reducer, a bearing mechanism and a control system, wherein the motor control precision requirement is high, the whole mechanism is large in size, high in cost, complex in arrangement and low in running efficiency, and particularly for extremely high wind speed and high torque adjustment, the problems are more remarkable, and the manufacturing technical requirement is higher. The patent document CN105464901a discloses a full-range non-blocking fluid energy conversion device, the main structure of which comprises a rotary component and a power generation motor, wherein a plurality of pneumatic impellers are arranged on a main rotary disk in the rotary component in a constant central angle manner, the transmission between a central fluted disc on a main rotary disk shaft and a fluted disc of an impeller wheel shaft enables the rotation direction of the impeller wheel shaft to be the same as the revolution direction of the impeller wheel shaft, meanwhile, the revolution angle alpha generated by the impeller wheel shaft along with the main rotary disk is 2 times of the rotation angle beta of the impeller wheel shaft, and when the steering rudder of a main shaft of the rotary disk is consistent with the fluid flow direction, the rotary component can realize maximum energy conversion operation in the state. Patent document CN112963285A gives a technical solution for an energy conversion unit of a multi-channel gradient rotary disk based on the above patent document.
