Technical field
The present invention relates to wind energy power technology field, PID control system of more particularly to a kind of wind-driven generator based on temperature information.
Background technology
In recent years, with the fast development of social industry, the mankind are increasing to the demand of the energy, and due to traditional energy, such as coal, oil, natural gas are non-renewable energy resources, therefore energy problem becomes is growing tension；Find the new energy and there is very important effect to human development.
It is well known that wind-power electricity generation is the kinetic energy kept watch switchs to electric energy.Wind energy is increasingly paid attention to by countries in the world as a kind of regenerative resource of cleaning.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 × 10^9MW, and wherein available wind energy is 2 × 10^7MW, and the water energy total amount than developing on the earth is also big 10 times.Wind is utilized by people very early -- mainly by windmill to draw water, flour milling etc., and present, what people were interested is how to use wind to generate electricity.THE WIND ENERGY RESOURCES IN CHINA is enriched, about 1,000,000,000 kW of the wind energy content that can be developed, wherein, about 2.53 hundred million kW of land wind energy content (land is liftoff 10m height material computations), it is marine can development and utilization about 7.5 hundred million kW of wind energy content, altogether 1,000,000,000 kW.And the end of the year 2003 whole nation electric power about 5.67 hundred million kW of installation.Wind is that do not have one of energy of public hazards.And it is inexhaustible.For hydropenia, short bunker and ungetable offshore islands, Pastoral Areas, mountain area and plateau band, utilize wind-power electricity generation treatment in accordance with local conditions, be especially suitable for, be well worth doing.
Found by long-term practice：Wind-driven generator is mainly by wind-force to realize generating electricity; therefore; wind-driven generator generally requires foundation in wind energy resources than more rich spacious place; generally; where this wind energy is more spacious; its environmental condition is more severe, therefore the generation of the extreme weather such as hurricane or torrential rain often occurs；Once and there is above-mentioned extreme weather, the accident that the stator winding or mover winding of electromotor are often short-circuited occurs；When short circuit accident occurs, the temperature of stator winding or mover winding in electromotor drastically will be raised, therefore, design and develop a kind of wind-driven generator that there can be more high safety factor seems it is particularly important based on the PID control system of temperature information.
The content of the invention
The technical problem to be solved in the present invention is：A kind of PID control system of wind-driven generator based on temperature information is provided.When the temperature of the stator winding or mover winding of electromotor is sharply increased, PID control system of the wind-driven generator based on temperature information can close wind-driven generator in time.
The present invention is adopted the technical scheme that by solving technical problem present in known technology：
A kind of PID control system of wind-driven generator based on temperature information, including for controlling the wind driven generator controller of wind-driven generator working condition；It is characterized in that：At least also include：
For the temperature sensor of measure field temperature；The temperature sensor is non-contact temperature sensor；The temperature sensor is installed on the stator winding of wind-driven generator；
PID controller, the lead-out terminal of the temperature sensor are electrically connected with the input terminal of PID controller by analog-digital converter；
The lead-out terminal of the PID controller is electrically connected with the control terminal of wind driven generator controller；Gsm communication module is electrically connected with the I/O terminals of the PID controller.
Further：The temperature sensor is fibre optic temperature sensor.
Further：The temperature sensor is no less than two；At least one temperature sensor is installed on the mover winding of wind-driven generator.
The present invention has the advantages and positive effects that：
By adopting above-mentioned technical proposal, the present invention can carry out monitor in real time to the temperature of the stator winding of wind-driven generator and mover winding, when the temperature of the stator winding or mover winding of wind-driven generator is too high, PID controller then can close electromotor the very first time, prevent the generation of dangerous accident, simultaneously, due to being electrically connected with gsm communication module on the I/O terminals of the PID controller, therefore the working condition of live PID controller can be occurred to the control terminal of distal end, and then more in-situ datas are provided for engineer.
