Abstract

The invention provides a device and method for guiding out harmful gas at the tower bottom of an offshore wind generating set. The device comprises a gas discharge unit, a data processing unit, a first control unit, a gas detection unit, a second control unit and a start-stop detection unit, wherein the first control unit is used for logic control, and is used for controlling the gas discharge unit to circularly and intermittently start and stop based on the theoretical operation duration and the theoretical standby duration calculated by the data processing unit, and the second control unit adopts feedback control, and judges whether to intervene in the logic control of the first control unit based on the detection result of the gas detection unit. According to the invention, discharge of harmful gas at the tower bottom is achieved through logic control, feedback control and gas export while discharge of harmful gas at the tower bottom can be guaranteed through a back-up power source under the condition that a power grid is powered off, so that personnel safety is protected, damage to electrical equipment is reduced, and the service life of the electrical equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a device and method for exporting harmful gas from the tower bottom of an offshore wind power generating set. Background technique [0002] Offshore wind turbines operate in the harsh marine environment all the time. The cost and difficulty of maintenance and depreciation account for a large proportion of operating costs. The safe and long-term operation of offshore wind turbine equipment and the safety and health of maintenance personnel will also become more and more serious. Having attention. A considerable proportion of equipment damage and aging of offshore wind turbines is directly or indirectly caused by corrosion, among which salt spray, hydrogen sulfide, and sulfur hexafluoride are the most prominent. Due to the universal awareness of salt spray, corresponding protective measures have been taken at the beginning of offshore wind power design. However, for ...
