Description
Technical field
The present invention relates to a kind of wind-power electricity generation master control system control technique, particularly a kind of megawatt level wind power generation master control system.
Background technique
In recent years, have benefited from the growth requirement of country policy guiding and international clean energy resource, China's wind-powered electricity generation is installed with average annual 100% speed fast development, to the end of the year 2009, China occupies the whole world the second with 2,610 ten thousand kilowatts electric motor power, and the U.S. totally installs 3,516 ten thousand kilowatts and is sure to occupy the umber one.
The quick growth of demand has also driven the manufacturing fast development of China's wind power equipment.By in by the end of April, 2009, domestic wind-powered electricity generation unit MANUFACTURER has 80 families nearly.Main blower fan manufacturing firm all is devoted to expand the scale of production in order to seize market fast, unable the such technology content high product of control system is carried out independent development, and is therefore many directly from foreign brand name company product purchasing or imported technology.From China's present case; other parts of blower fan; comprise core components such as blade, gear-box, generator, bearing realize substantially the production domesticization supporting; and the autonomous supporting scale of blower fan control system is also quite not as people's will; dependence to foreign brand name is still bigger, is still the weakest link in the wind power equipment manufacturing industry.Especially to the research of high-power unit variable speed constant frequency control technique more than the MW class, the thing of recent years especially, this fell behind for two ten years than blower fan advanced technology is national.Wind-power electricity generation is a hi-tech industry, no matter complete machine control, systems simulation still be that product maintenance is maintained, all very complicated, yet owing to lack the independent intellectual property right of control system, even if what introduce also is the non-core technology that is controlled by other people, though kit hardware price that external blower fan control system is high and high service fee have made domestic main frame producer can't bear the heavy load, also can only exceedingly rely on offshore company.
China starts late this technical field, before address, China's wind-powered electricity generation manufacturing industry is just to be rapidly developed since nearest 4 years in 2005, domestic main blower fan manufacturing firm is in order to seize market fast, all be devoted to expand the scale of production, unable the such technology content high product of control system is carried out independent development, therefore many directly from offshore company's product purchasing or imported technology.With regard to the requirement of blower fan control system itself, truly have its particularity and complexity.From hardware, blower fan control system is installed in the environment near nature with blower fan, and work has bigger vibration, on a large scale under the such complex conditions of temperature variation, strong electromagnetic, so its hardware requirement is more much higher than General System.From software, blower fan will be realized controlling automatically completely, the perfect control software that must have a cover to adapt with it.Master control system, pitch-controlled system and frequency variator need collaborative work just can be implemented in the following maximal wind-energy capture of low wind speed, decide rotating speed and the constant frequency under big wind speed, the operation of permanent merit under the medium wind speed, and this need have a cover advanced person, complicated control algorithm in these several big parts.
Blower fan control system is the system that combines with the fan characteristic height, the control software that comprise master control, becomes oar and frequency variator is the algorithm complexity not only, and the setting of its parameters and blower fan itself are got in touch closely, the task of blower fan control system is not only that realization is to the increasingly automated monitoring of blower fan and to mains supply, but also must realize minimizing of maximization that wind energy is caught and load by suitable control, general automation enterprise promptly enables to develop model machine, also be difficult to be verified, just promote difficulty more.Carry out such exploitation and the blower fan MANUFACTURER of middle and small scale is unable.Therefore, be necessary very much to develop a cover and have independent intellectual property right, the wind-powered electricity generation master control system of core technology on top of, to overcome above-mentioned difficulties.
Summary of the invention
The objective of the invention is to provide for the deficiency that solves above-mentioned technology a kind of can realize regulating automatically to blade pitch angle, generator torque, and the convenient megawatt level wind power generation master control system of generating electricity by way of merging two or more grid systems of realizing.
In order to achieve the above object, a kind of megawatt level wind power generation master control system that the present invention is designed, it comprises main control unit, upper location supervisory, variable blade control system and frequency conversion system, described main control unit by tower at the bottom of control cabinet and cabin control cabinet form, control cabinet is provided with universal I module at the bottom of master cpu module, remote I expansion optical fiber primary module, CANOpen communication primary module, RS232 expansion module, the tower, first multi-mode optical interface, four electricity mouthful industrial switch, single-mode optics electric transducer, the first tail optical fiber box, upper-position unit, multi-mould optical fibre on the spot at the bottom of the tower; The cabin control cabinet is provided with remote I expansion optical fiber from module, RS485 module, cabin universal I mould, second multi-mode optical interface, four electricity mouthful industrial switch, the second tail optical fiber box; Main control unit is connected with upper location supervisory by the single-mode optics electric transducer, and main control unit is connected with frequency conversion system by CANOpen communication primary module, and main control unit links to each other with variable blade control system by the RS485 module.
Because blower fan work exists running state, halted state, outage state and the anxious state four kinds of different conditions from high to low that stop.All need state during blower fan work according to unit; by the control flow of setting tuning system, hydraulic system, pitch-controlled system, braking system, power electronic devices are controlled; conversion between the realization state; therefore transformation and control flow between the working state are set for convenience, guarantee the safe operation of unit.Control cabinet is connected with frequency conversion system by CANOpen communication primary module at the bottom of the tower, main control unit is connected with ups power by the RS232 expansion module in the control cabinet at the bottom of the tower, remote I expansion optical fiber primary module is connected with the first tail optical fiber box, and the RS232 expansion module is connected with first multi-mode optical interface, four electricity mouthful industrial switch; The single-mode optics electric transducer is connected with the first tail optical fiber box, connects single-mode optics electric transducer, the first tail optical fiber box, upper-position unit on the spot on first multi-mode optical interface four electricity mouthful industrial switch respectively, connects upper location supervisory by multi-mould optical fibre on the first tail optical fiber box.
Following the structure according to blower fan is the angle that changes blade owing to the function that becomes prize, change the rotating speed of blower fan, yaw motor rotates the cabin, follow the tracks of wind direction to obtain maximal wind-energy, the cabin control cabinet connects frequency conversion system by the RS485 module, the cabin control cabinet connects vibration transducer by cabin universal I mould, is connected from module, second multi-mode optical interface, four electricity mouthful industrial switch with remote I expansion optical fiber respectively by the second tail optical fiber box.
