Description
Technical field
The utility model relates to a kind of variable blade control system, and what be specifically related to is that a kind of wind-powered electricity generation exchanges variable blade control system.
Background technique
Along with non-renewable energy resources worldwide face exhausted awkward situation, for satisfying industrialized production and the human lives is required, people are to the concern of solar energy, wind-force, these renewable energy sourcess of waterpower and utilize day by day and promote.Wherein, wind-power electricity generation is subjected to the extensive attention of various countries as a kind of developmental technology of new energy resources of maturation relatively that developed.
Variable blade control system is one of core component of wind power generating set, its major function is the angle of coming regulator generator group blade according to the size of wind-force, change the angle of attack of air-flow to blade, the output power of wind-driven generator can be automatically adjusted according to the size of wind speed, the delivery efficiency that guarantees wind-driven generator is the highest, and output is in rated power.
At present, the pitch-controlled system of China's wind-power electricity generation group adopts the direct current pitch-controlled system more, and what promptly the driver element of pitch-controlled system adopted is dc driver and direct current generator.The ubiquitous problem of direct current pitch-controlled system is that the specific power of direct current generator is little, cost height, troublesome maintenance etc.Current, wind power generating set per kilowatt cost continues to reduce, and falls over a large area cost at wind power plant, improves under the overall situation of cost performance, and the above-mentioned shortcoming of direct current pitch-controlled system is also just more outstanding.
The driver element that exchanges pitch-controlled system adopts AC motor and ac driver.Ac motor structure is simple, reliability and durability, cost is low, easy to maintenance, just in time overcome the above-mentioned shortcoming of direct current generator.Exchange the application of pitch-controlled system in wind power pitch-controlled system also more and more widely.Compare the direct current pitch-controlled system, the shortcoming that exchanges pitch-controlled system is, in a single day system breaks down, exchange pitch-controlled system and can not utilize the reserve DC electrical source (generally being battery pack or super capacitor group) of pitch-controlled system directly to put away the oars, and the direct current pitch-controlled system can directly be added to the reserve DC electrical source on the direct current generator and puts away the oars.How improving the reliability that exchanges pitch-controlled system, is the most important thing that exchanges the pitch-controlled system development.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and provides a kind of wind-powered electricity generation to exchange variable blade control system, makes the upper-position unit PLC of variable pitch driver break down, and becomes the control that the oar device wouldn't be subjected to PLC, independently finishes the function of putting away the oars.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of wind-powered electricity generation exchanges variable blade control system, comprise the PLC controller and exchange variable pitch driver, described PLC controller is connected power supply with described interchange variable pitch driver, described interchange variable pitch driver connects limit switch, described interchange variable pitch driver comprises monitoring port, the given module of speed, reset signal module and feedback signal module, and described PLC controller connects described monitoring port, the given module of described speed, described reset signal module and described feedback signal module.
The beneficial effects of the utility model are:
The utility model modern design, simple in structure, effect is obvious, has realized the reliable detection of variable pitch driver to the PLC working state, has improved interchange pitch-controlled system reliability of operation.
Description of drawings
Fig. 1 is overall structure figure;
Fig. 2 is a flow chart.
Number in the figure explanation: 1, PLC controller, 2, exchange and become the oar controller, 3, limit switch, 4, power supply, 5, monitoring port, 6, the given module of speed, 7, the reset signal module, 8, the feedback signal module.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Figure 1, a kind of wind-powered electricity generation exchanges variable blade control system, comprise PLC controller 1 and exchange variable pitch driver 2, described PLC controller 1 is connected power supply 4 with described interchange variable pitch driver 2, described interchange variable pitch driver 2 connects limit switch 3, described interchange variable pitch driver 2 comprises monitoring port 5, the given module 6 of speed, reset signal module 7 and feedback signal module 8, and described PLC controller 1 connects described monitoring port 5, the given module 6 of described speed, described reset signal module 7 and described feedback signal module 8.
Principle of the present utility model:
With reference to shown in Figure 2, during system works, PLC sends the monitoring port of the pulse signal of 2HZ to driver incessantly, will carry out the order that all control terminal PLC send as long as driver detects this state signal, and the limit switch signal of blade is inoperative.In case PLC breaks down, this state signal will interrupt, at this moment will to look all input control signal be invalid to driver, limit switch signal works simultaneously, driver will be put away the oars according to the rotating speed of setting, and the limit-switch positions signal arrives the rear driving device and stops output (put away the oars and finish).Because under the normal condition, blower fan all is the limit-switch positions machine from blade, therefore, and when limit switch signal has also avoided system to play machine, driver and the competition of PLC life period (PLC does not also move and gets up to cause variable pitch driver to can't accept the monitoring port signal), and cause erroneous judgement.
