Description

Wind-driven generator is based on the PID control system of humidity information
Technical field
The utility model relates to wind energy power technology field, particularly relates to the PID control system of a kind of wind-driven generator based on humidity information.
Background technique
In recent years, along with the fast development of society's industry, the demand of the mankind to the energy is increasing, and due to traditional energy, such as coal, oil, rock gas are non-renewable energy resources, and what therefore energy problem became is growing tension; Find the new energy, to human development, there is very important effect.
As everyone knows, wind-power electricity generation is that the kinetic energy of keeping watch transfers electric energy to.Wind energy, as a kind of clean renewable energy sources, is more and more subject to the attention of countries in the world.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, than the water energy total amount that the earth can develop also large 10 times.Wind is utilized by people very early--mainly to be drawn water by windmill, flour milling etc., and now, people are interested is how to utilize wind to generate electricity.THE WIND ENERGY RESOURCES IN CHINA is enriched, the wind energy content that can develop about 1,000,000,000 kW, wherein, land wind energy content about 2.53 hundred million kW (land is liftoff 10m height material computation), marine can wind energy content about 7.5 hundred million kW of development and utilization, amount to 1,000,000,000 kW.And whole nation electric power installation in the end of the year 2003 about 5.67 hundred million kW.Wind is one of energy not having public hazards.And it is inexhaustible.For lack of water, short bunker and ungetable offshore islands, Pastoral Areas, mountain area and area, plateau, utilize wind-power electricity generation with suiting measures to local conditions, very applicable, be well worth doing.
Found by long-term practice: wind-driven generator mainly relies on wind-force to realize generating, therefore, it is spacious more local than more rich that wind-driven generator generally needs to be based upon wind energy resources, generally, the place that this wind energy is more spacious, its environmental conditions is relatively more severe, and therefore the generation of the extreme weather such as hurricane or cloudburst often can occur; And once there is above-mentioned extreme weather, the accident that the staor winding of generator or mover winding often can be short-circuited occurs; When short circuit accident occurs, the humidity of the staor winding in generator or mover winding will sharply raise, and therefore, designs and develops a kind of wind-driven generator can with more high safety factor and seems it is particularly important based on the PID control system of humidity information.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of wind-driven generator based on the PID control system of humidity information.When the staor winding of generator or the humidity of mover winding sharply increase, this wind-driven generator can close wind-driven generator in time based on the PID control system of humidity information.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:
Wind-driven generator, based on a PID control system for humidity information, comprises the wind driven generator controller for controlling wind-driven generator working state; It is characterized in that: at least also comprise:
For the humidity transducer of measure field humidity; Described humidity transducer is lithium chloride humidity transducer; On the staor winding that described lithium chloride humidity transducer is installed on wind-driven generator or mover winding;
PID controller, the Out let of described lithium chloride humidity transducer is electrically connected with the input terminal of PID controller by analog-digital converter;
The Out let of described PID controller is electrically connected with the control terminal of wind driven generator controller; The I/O terminal of described PID controller is electrically connected with gsm communication module.
Further: described lithium chloride humidity transducer is no less than two.
The advantage that the utility model has and good effect are:
By adopting technique scheme, the utility model can be monitored the humidity information of the staor winding of wind-driven generator and mover winding, when the staor winding of wind-driven generator or the humidity of mover winding too high time, PID controller then can close generator the very first time, prevent the generation of dangerous accident, simultaneously, due to the I/O terminal of described PID controller being electrically connected with gsm communication module, therefore the working state of on-the-spot PID controller can be occurred to the control terminal of far-end, and then provide more in-situ data for engineer.
Accompanying drawing illustrates:
Fig. 1 is the circuit block diagram of the utility model preferred embodiment;
Fig. 2 is the partial circuit diagram of the utility model preferred embodiment, is mainly used in the internal circuit showing PID controller.
Embodiment
For model utility content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of wind-driven generator, based on the PID control system of humidity information, comprising:
For controlling the wind driven generator controller of wind-driven generator working state;
For the humidity transducer of measure field humidity; Described humidity transducer is lithium chloride humidity transducer; On the staor winding that described lithium chloride humidity transducer is installed on wind-driven generator or mover winding;
PID controller, the Out let of described lithium chloride humidity transducer is electrically connected with the input terminal of PID controller by analog-digital converter; Fig. 2 is the internal circuit of PID controller, mainly comprises an input terminal, four comparators and an Out let;
The Out let of described PID controller is electrically connected with the control terminal of wind driven generator controller; The I/O terminal of described PID controller is electrically connected with gsm communication module.
Working principle of the present utility model is: the humidity of humidity transducer to staor winding or mover winding is monitored in real time, and the humidity information monitored is sent to PID controller, PID controller is preset with the upper limit threshold of humidity, when humidity information reaches upper limit threshold, PID controller then exports a customizing messages instruction, is such as high level, and now wind driven generator controller is once receive above-mentioned high level, then can close wind-driven generator, and then danger is reduced to minimum level.Meanwhile, the working condition at scene self is also sent to remote controllers by gsm communication module, for engineer provides first hand in-situ data by PID controller.
Further: described lithium chloride humidity transducer is no less than two.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
