A tidal current energy generating set and its yaw method

Abstract

The invention discloses a tidal current energy generator set and a yawing method thereof. The tidal current energy generator set comprises a tidal current energy hydraulic turbine set, a main support frame, a floating type ocean platform and a yawing system, a hole for lifting the tidal current energy hydraulic turbine set is formed in the floating type ocean platform, the main support frame passes through the hole, the lower part thereof is firmly connected with the tidal current energy hydraulic turbine set, the upper part is firmly connected with the yawing system, and the yawing system is supported above the floating type ocean platform through a yawing bracket. The yawing system of the tidal current energy generator set is arranged on the sea level, relevant data are sent to a master control system through an ocean environment detection system, the master control system controls the yawing of the yawing system, all the bidirectional tidal current energy can be captured, the usable power generation time is prolonged, and the power generation efficiency of the tidal current energy generator set is improved. The tidal current energy generator set is simple in structure and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of tidal current energy generation, in particular to a tidal current energy generating set and a yaw method thereof. Background technique [0002] Existing tidal current energy generating sets generally do not have a yaw system, and use two-way rotating power generation equipment to achieve energy capture when two-way incoming flow is achieved through a large-angle pitch system, or only capture energy from one-way tidal current, and some use yaw adjustment The yaw of the device is mainly adjusted by hydrodynamic performance, as disclosed in the invention patent application (application publication number: CN103758688A): the upper tower of the tidal current energy turbine yaw adjustment device is arranged on the lower tower fixed to the base through the yaw device On the frame, two adjusting blades are arranged symmetrically on the outer side of the upper tower respectively, and the lower tower forms a radial...

AI Technical Summary

Problems solved by technology

The yaw control mechanism needs to issue commands to the yaw system in real time according to the change of wind direction to achieve power optimization, and because the wind direction changes, the requirements for the control system are increased, which makes the overall generator set more complicated

[0004] It can be seen that the yaw system of the above-mentioned existing tidal current energy generator set obviously still has inconvenience and defects in structure, method and use, and needs to be further improved urgently.
