Description

Wind power generating set control gear based on the wind speed advanced prediction
Technical field
The utility model belongs to technical field of wind power generation, is specifically related to the wind power generating set control gear based on the wind speed advanced prediction.
Background technique
Current, in the epoch of scientific and technological high speed development, global energy is in short supply, and environmental problem becomes increasingly conspicuous.Wind energy has that reserves are huge, widely distributed, cleanliness without any pollution and reproducible characteristics, meets the requirement of human kind sustainable development, more and more is subject to the extensive concern in countries in the world and area.World's Wind Power Generation Industry develops rapidly recently, and wind-power electricity generation has become the important channel that solves the world energy sources shortage.Global Wind-energy resource reserves are huge, and the utilization of wind energy mainly is wind-power electricity generation, namely utilize wind-force to drive the air vane rotation, promote by the speed of speedup box with rotation again, impel the generator generating.Wind power generating set in most cases generally be positioned at the low temperature such as northwest, North China, northeast, windy and dusty zone or south humidity and coastal high corrosion area in China, and the position is all remoter.This environmental quality requires wind power generating set to have the characteristics such as good low temperature resistant, high humility, anti-blown sand, corrosion-resistant, stable performance, Maintenance free.
Because to be in environment abominable for wind-driven generator, so proposed very high requirement for aspects such as the performance of hardware system, Environmental Conditions, harsh like this natural condition make generator set work be subject to obvious impact.Because uncertainty, randomness, wave properties, the intermittent characteristics of wind speed for better utilizing wind-resources, improve the reliability of wind turbine control system.Mean wind velocity is larger, and ground surface is more coarse, and the percentaeg that gustiness surpasses mean wind velocity is just larger.After fitful wind arrives maximum wind speed, approximately spend l-2 second, wind speed will be less than half of mean wind velocity, and then another time maximum wind speed occurs.In wind energy turbine set, because the impact of fitful wind may cause the wind-driven generator rotating speed to rise suddenly, treat that after the of short duration fitful wind, the wind-driven generator rotating speed descends again, the at short notice large fluctuation of this rotating speed, will inevitably cause the fluctuation of output power, affect power generating quality; Even in the situation that fitful wind is excessive above rated wind speed, may cause the unexpected parking of wind-driven generator, start again subsequently initiating failure.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of wind power generating set control gear based on the wind speed advanced prediction, has the advantages that Security is good, reliability is high, look-ahead is controlled, controllability is good, cost is low.
In order to achieve the above object, the technical solution adopted in the utility model is:
Wind power generating set control gear based on the wind speed advanced prediction, the wind measuring system 1 of wind energy turbine set wind-driven generator unit and the data output end of anemometer tower 2 connect external server 4, weather forecast system 3 is realized data transmission by optical signal and external server 4, external server 4 is connected with centralized control center 8 by isolation mounting 9, and centralized control center 8 is connected with dispatching center 12.
Described centralized control center 8 comprises switchboard 5, internal server 6, engineer station 7 and the print system 10 of carrying out between any two data transmission by netting twine 11.
Described centralized control center 8 is by switchboard 5 and dispatching center's 12 the transmission of datas.
Described centralized control center 8 by the tower of switchboard 5 and wind power generating set at the bottom of control cabinet 15 communicate, control cabinet 15 and cat head control cabinet 14 communication connections that are arranged in the cabin 16 at the bottom of the tower, cat head control cabinet 14 blade 17 outer with being arranged at cabin 16 is connected, and centralized control center 8 sends operational order and carries out change oars, driftage by cat head control cabinet 14 control blades 17.
Described wind measuring system 1 is made of the anemoclinograph 13 that is arranged on each wind-driven generator of wind energy turbine set.
Compared with prior art, the beneficial effects of the utility model are:
One, look-ahead control: because the sudden and persistency of fitful wind is short, the geographic range of adding wind field is also larger, fitful wind is detected in the wind field periphery, intensity is larger, when to the wind field central position, fitful wind intensity will weaken, even disappear, in order to address this problem, utilize the centralized control center to pass through Weights-selected Algorithm, multiply by corresponding weights namely for each wind-driven generator, weights successively decrease successively from outside to inside, when peripheral sensor detection fitful wind, signal are passed to each wind-driven generator in the wind field like this, each wind-power electricity generation chance with this signal times with self corresponding weights, the result of calculation that draws is thus adjusted action, that is to say from the nearest wind-driven generator action maximum of fitful wind, even wants feathering, and from just less even action of the wind-driven generator action of fitful wind away from more, can control in advance for the impact of fitful wind.
Two, security of system and reliability: avoided by the way fitful wind interim, the disconnected situation of erroneous judgement occurs in each wind-power electricity generation chance, the output-power fluctuation that the action that leads to errors causes has guaranteed whole wind energy turbine set stablizing in the next interim wind-driven generator rotating speed of fitful wind and output power on the whole.The leading power control that detects can guarantee from measuring the source accuracy of survey data based on wind speed, for power control provides reliable Data Source, guarantee the optimization of wind-driven generator economic benefit, the stability of maintenance system realizes that the fault treatment of wind-driven generator is hierarchical.
Therefore, the utlity model has the characteristics that Security is good, reliability is high, look-ahead is controlled, controllability is good, cost is low.
