Description
Technical field
The present invention relates to wind-driven generator measuring technology, particularly relate to the testing results of a kind of fan master control system
System and method.
Background technology
The control system of blower fan is the important component part of blower fan, it carry fan monitoring, be automatically adjusted,
Realize maximal wind-energy capture and ensure the vital tasks such as good electrical network compatibility.The control system of blower fan
Mainly by monitoring system, master control system, variable blade control system and frequency conversion system (converter), driftage system
A few part of uniting forms.Wherein, fan master control system is the main body of blower fan control system, is equivalent to the brain of people,
Can realize automatically startup, automatic direction regulating, automatic speed regulation, auto-parallel, automatic parallel off, fault autostop,
Automatically cable unwinding, maximal wind-energy catch and important control and the defencive function etc. such as automatic record and monitoring,
Being the central control system of blower fan, the overall performance of blower fan is played by the technical performance of fan master control system product
Critical effect.
One new wind-driven generator (abbreviation blower fan) master control system or new master control algoritic module, in exploitation
Early stage, mid-term and put into the research and development later stage before on-the-spot trail run, be also required for carrying out in factory
Sufficiently simulating, verifying test, to ensure R&D target and the properties of product in each stage.
At present, fan master control system is carried out before the used means of validation test mainly have several:
1, the simulation software utilizing wind-powered electricity generation field specialty is controlled the emulation of strategy.Such as, GH is utilized
Blade software carries out validation test, and the method is also currently used relatively broad method, and it can be easily
Amendment control strategy, verifies the effectiveness of control strategy under different operating modes.But, the master control of a blower fan
System not only comprises control strategy, also includes the software and hardware system of operation control strategy and the electric of periphery
Loop, the method is generally difficult to provide one complete comprehensive to test for whole wind-driven generator master control system
Card means；Further, a lot of in the case of, due to the program of actual fan master control system operation with from this system
The master control strategy or the algorithm routine that manually extract participation simulating, verifying are typically under two kinds of programmed environments very
To being that different programming language realizes, in this case, the two property that is that there is some difference.
2, direct current or alternating current generator is utilized to simulate the matter simulating system that prime mover wind wheel is constituted.The method due to
, there is not simulation modeling link in all material objects of electromotor, current transformer, can be to whole fan master control system
Effectively emulate；But it is big that shortcoming is floor space, and cost is high, and not malleable difference unit capacity
In the case of corresponding parameter, be limited to the speed regulation capacity of prime mover, be not easy to simulate various fast-changing wind
The impact of speed.After this kind of method is applicable to producer's blower fan sizing mass production, blower fan dispatch from the factory before emulation
Test.Even if so, the emulation testing major part of blower fan is to complete, equally with each subsystem local test
It is difficult to the test of Global Uniformity；
3, physics programmable logic controller (PLC) (PLC, Programmable Logic Controller) is utilized to take
Build analogue system.The method is exploitation blower fan simulated program in a physics PLC system, is used for simulating product
Give birth to or receive the environment needed for fan master control system and electrical input signal and air-blower control command output,
Exploitation blower fan simulation software with by the way of physical electrical is connected, realize signal between fan master control system
Alternately.The method it is generally required to the mode utilizing manual codes to program progressively creates blower fan simulated program, this
In the case of Zhong, the usual construction cycle can be the longest, and the simulated program cost of exploitation is high, and type adaptability is narrow.
In a word, existing that fan master control system carries out the used means of validation test is inefficient, motility
Difference.
