Description

A kind of detection system of wind generating set pitch control accumulator and detection method thereof
[technical field]
The present invention relates to a kind of detection system and detection method thereof of wind generating set pitch control accumulator
[background technology]
Pitch-controlled system is the important component part of wind power generating set, and pitch-controlled system is controlled wind speed round through regulating blade, in addition; Pitch-controlled system still is first brake system of whole unit, and in recent years, a lot of blower fans " driving " accident had taken place in China; Through investigation to culprit; Find that majority is that feathering causes because the pitch-controlled system battery failure causes promptly, so the monitoring of pitch-controlled system battery performance is an important content of fan operation and maintenance.
In recent years, analysing valve control type lead-acid accumulator battery had obtained widely using, and most pitch-controlled system producer all adopts analysing valve control type lead-acid accumulator battery accumulator in support; Battery management module is all arranged in the pitch-controlled system usually, be responsible for, yet battery management module is the mode that adopts floating charge to the charging of battery battery charge and the running status that detects battery; Floating charge for a long time; Have very big damage the serviceable life to battery, and As time goes on, performance will descend; In order to solve the problem in serviceable life of analysing valve control type lead-acid accumulator battery; Each relevant industries department has all made clear and definite regulation to the care and maintenance of accumulator, and there is clearly regulation in wind power plant, and doing at least in 1 year at the operation accumulator in the transformer station discharges and recharges experiment 1 time fully.
Traditional detection method just is to use a kind of portable battery checkout equipment, then battery is carried out the degree of depth and discharges and recharges experiment, through this equipment battery performance is made professional assessment.The advantage of this method is that the detection method through specialty can draw and detects data accurately, makes the assessment of specialty to battery performance, and shortcoming is to need special expense purchase of equipments; Need get into wheel hub inside when detecting needs dismounting battery to be detected simultaneously, and inconvenience increases human cost; And once discharge and recharge experiment and generally all surpass 10 hours; Detect length consuming time, wind energy turbine set is caused the bigger generated energy loss that gets, the practical operation feasibility is low.
Blade is to be driven by external power source during the unit orderly closedown; Only (for example: trigger scram button at emergency; Hypervelocities etc.) time, pitch-controlled system is just used accumulator and is driven the urgent feathering of blade, if descending appears in accumulator property; Battery is when driving the blade feathering to urgent stop position, and the real-time transient data during the blade feathering can occur unusually.
In the wind-powered electricity generation industry, blower fan " driving " accident is very serious accident, and the economic loss that causes is also in time changed if can find the battery that performance descends in advance in necessarily, then just can avoid " driving " accident that causes because of battery failure.And the accumulator that performance descends can also continue to use after safeguarding, the accumulator of complete failure can only be to do to scrap processing, just can practice thrift a large sum of expense purchasing on the project of new accumulator like this.
Along with the development of wind-powered electricity generation industry, wind-powered electricity generation periphery product is constantly perfect, has occurred a kind of online battery detecting equipment at present; Different with conventional detection devices, this equipment is installed with change oar cell integral, though have the advantage of the performance situation of real time on-line monitoring battery; But still can increase very big expense; Even need change battery case body structure, and be installed in the wheel hub owing to this equipment simultaneously, very high to the bad working environments adaptability requirement of this equipment.
[summary of the invention]
