At present, many areas in the whole world are populous, lack the place of implementing the large-scale wind electricity solution.And in underpopulated area naturally, national governments bring certain difficulty also for the construction of wind energy turbine set to the protection of ecological and natural landscape.And marine wind-force can not receive the influence of mountain range or buildings, and Oversea wind more is prone to prediction than the land simultaneously, and turbulent flow is less.In addition, the sea does not have the problem of limited space.Therefore, the neritic province domain of along the coastline often is the desirable place of building marine wind electric field.Offshore wind farm has obtained vigorous growth.
Yet marine climatic environment is extremely harsh, and aerogenerator often receives the erosion of high temperature, high humidity and salt fog, influences the safe operation and the operating cost of blower fan:
(1) because marine air humidity is bigger, when reaching condensation point, be prone on components and parts, produce condensation, can significantly shorten the serviceable life of electronic component like this, and mechanical part is produced corrosion, these all can cause components and parts and even whole blower fan disorderly closedown.
(2) environment that the while sea is moist produces and contains acid salt fog gas in a large number, at high temperature can quicken to make the corrosion oxidation or the detection of detection means, controller and the pass heavy mail etc. of the sensitivity in the control system to lose efficacy;
(3) offshore wind turbine field maintemance inconvenience, characteristics such as maintenance cost height.
Therefore, the safe reliability to the MCS of blower fan has proposed special requirement.
The utility model content
The offshore wind farm development investment is huge, and the fan operation environmental requirement is harsh, and has higher risk than landwid electric field, therefore, must adopt an effective measure and control risk.For the reliability and control project risk of protecting the naval counterpart blower fan, strengthen the reliability design of wind power generating set MCS, the utility model provides a kind of offshore wind generating group intelligent humidity control system.
The utility model solves the technical scheme that its technical matters adopted:
A kind of offshore wind generating group intelligent humidity control system, this system is made up of pick-up unit, harvester, control device and actuating unit; Said pick-up unit comprises humidity sensor and humidity CS; Harvester is the humidity acquisition module; Control device comprises Programmable Logic Controller and dehumidifying relay; Actuating unit is a dehydrating unit; Said humidity sensor, humidity acquisition module, Programmable Logic Controller, dehumidifying relay and dehydrating unit connect in order; Said humidity CS is connected with the dehumidifying relay.
Further, said dehydrating unit comprises dehumidifier and/or air-conditioning.
The offshore wind generating group intelligent humidity control system of the utility model; Humidity sensor is detected data transmission to the humidity acquisition module; The humidity acquisition module imports humidity value into Programmable Logic Controller; Programmable Logic Controller confirm to drive the dehumidifying relay coil according to the interior humidity setting value and gets electricly, simultaneously, also can the dehumidifying relay coil got according to self humidity set point adhesive of humidity CS; The final dehydrating unit (dehumidifier, air-conditioning) that starts moves, and the interior device of equipment and switch board normally moves in the assurance cabin.
Compared with prior art, the beneficial effect of the utility model is:
In view of the reliability requirement height of offshore wind generating, the inconvenience in the maintenance, characteristics such as maintenance cost height; Therefore, adopt redundant humidity controlling Design on the offshore wind farm unit MCS, can pass through software and electric duplicate protection; Control dehydrating unit (dehumidifier, air-conditioning) dehumidifying is if software can be controlled through another set of system when deadlock or the inefficacy of humidity CS; Guarantee that equipment operation is at the optimum humidity environment in cabin and the switch board; Thereby improve the reliability design of offshore wind generating, reduce operation risk, prolong the serviceable life of unit.
Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.
Description of drawings
Fig. 1 is the utility model offshore wind generating group intelligent humidity control system structural representation.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1, a kind of offshore wind generating group intelligent humidity control system of the utility model is made up of pick-up unit, harvester, control device and actuating unit; Pick-up unit comprises humidity sensor and humidity CS; Harvester is the humidity acquisition module; Control device comprises Programmable Logic Controller and dehumidifying relay; Actuating unit is a dehydrating unit; Humidity sensor, humidity acquisition module, Programmable Logic Controller, dehumidifying relay and dehydrating unit connect in order; The humidity CS is connected with the dehumidifying relay.Wherein, dehydrating unit comprises dehumidifier and/or air-conditioning.
The naval counterpart wind power generating set MCS of the utility model, realize by dehydrating units such as software and electric dual control dehumidifier and air-conditionings:
First kind; Software control: be installed in cabin and the switch board humidity sensor separately the humidity value of check point be input to the humidity acquisition module; The humidity acquisition module imports these humidity values into Programmable Logic Controller, and Programmable Logic Controller carries out judgment processing according to the humidity set point in the internal processes, when this space humidity is higher than the Programmable Logic Controller humidity set point; Driving dehumidifying relay coil gets electric, starts dehydrating units such as dehumidifier and air-conditioning and dehumidifies; When humidity is lower than the Programmable Logic Controller humidity set point, stop dehumidifying.
Second kind, electrical control: when being installed in humidity CS in cabin and the switch board and detecting current environment humidity and be higher than the setting value of this humidity CS, it is electric that its corresponding dehumidifying relay coil is got, and dehydrating units such as dehumidifier and air-conditioning are started working; When this space humidity was lower than the setting value of humidity CS, the humidity CS broke off, and dehydrating units such as dehumidifier and air-conditioning are quit work.
Through above-mentioned software and two electric cover humidity control redundancy designs, can realize that blower fan control system and blower fan close heavy mail and effectively ensure.
