Description of drawings
Fig. 1 is a working principle schematic representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, present embodiment is single power cell with separate unit blower fan or solar cell array, by a plurality of power cell DC parallel power supplies, regulate and control via the intelligent controller that programmable controller (PLC), drain charge device and variable-frequency governor are formed, make submersible pump can keep good frequency control of motor speed running state, realize unsteady flow amount water lift.Intelligent controller moves system and carries out program control and automatic management, has the maximal power tracing function.Storage battery need not be joined during water lift by system, efficient height, reliability height.
Key technology:
As can be seen from Figure 1, the key technology of present embodiment is the technical problem that solves many typhoons machine and solar cells parallel connection; How the electric energy that solution produces blower fan and solar cells is transformed into the technical problem that can satisfy the unsteady flow of proper functioning under the variable frequency speed modulation of asynchronous motor state; Resolution system can use the problem of the Submerged Motor Pumps that AC induction motor drags; Solution utilizes programmable controller (PLC) to carry out intelligent unified management and control, realizes the technical problem of electromechanical integration.
First resolution system can use the problem one of the Submerged Motor Pumps that AC induction motor drags to transform variable-frequency governor:
Normally used submersible pump generally all is the water pump of Asynchronous Motor Driving, and input 380V50Hz constant frequency and constant voltage electric current carries out constant current amount water lift.But the electric energy that photovoltaic cell produces is the direct current (d.c.) that voltage floats and changes, and the electric energy that wind-driven generator produces is that voltage and frequency are all at the threephase AC of transient changing.Such electric current is can't directly drive the submersible pump that threephase asynchronous machine drags to draw water.
But asynchronous motor can be operated under the frequency control of motor speed state, and just the flow of water lift can become the change flow by the constant current quantitative change.The condition of asynchronous motor frequency-changing speed-regulating operation is to keep its every grade main flux constant, as long as making the voltage of its operating current and the ratio (V/f) of frequency is a fixed number between the 7-8, just can make every grade of main flux of asynchronous motor constant, asynchronous motor just can be under the frequency control of motor speed state proper functioning.
And AC frequency conversion speed regulator just can make the voltage of output current and the ratio of frequency remain on constant voltage-frequency ratio substantially, reference frequency output: 0-80Hz.Such output current can drive threephase asynchronous frequency control of motor speed operation fully, makes Submerged Motor Pumps unsteady flow amount water lift.But the AC frequency conversion speed regulator input is 380V constant voltage 50Hz constant frequency electric current.
How problem just becomes the variable-frequency governor that AC frequency conversion speed regulator is transformed into direct current (d.c.) that can the input voltage pulsation like this.Theory and practice all confirms through appropriate reconstruction, output terminal to the rectifier of variable-frequency governor, to the direct current (d.c.) of the chopper of variable-frequency governor input less than the ripple voltage of 620V, variable-frequency governor can proper functioning, can export the threephase AC of 0-80Hz.That is to say that AC frequency conversion speed regulator can be transformed into the variable-frequency governor of the direct current (d.c.) of input voltage pulsation.So just possessed asynchronous motor and be operated in primary condition under the frequency control of motor speed state.
Second solves the technical problem that the electric current that blower fan and solar cells are produced can satisfy improved variable-frequency governor proper functioning
Because the electric energy that photovoltaic cell produces is the direct current (d.c.) that voltage floats and changes, and the electric energy that wind-driven generator produces is that voltage and frequency are all at the threephase AC of transient changing, want multi fan and wind light mutual complementing, low-cost again, then wind turbine respectively after the rectification and the solar cells DC parallel be the best approach.
Electric current behind the DC parallel has become the direct current (d.c.) of mains ripple.
If wind turbine is distinguished after the rectification and the solar cells DC parallel, by the drain charge device of programmable controller (PLC) control the direct current fluctuation voltage of blower fan and solar cells output is carried out strictness again and control automatically, the direct current fluctuation voltage behind blower fan and the solar cells DC parallel is remained at below the DC620V.This just can satisfy the needs of improved variable-frequency governor.
How the electric energy of blower fan and solar cells generation is transformed into the technical problem that can satisfy the unsteady flow of proper functioning under the variable frequency speed modulation of asynchronous motor state and just obtains well comprehensively solution like this.
The 3rd solves the technical problem of intelligent unified management:
The utility model claimant has rich practice experience and good programming technique, but design compilation goes out good software, make programmable controller (PLC) can to fan operation, storage battery state-of-charge and inverter output, maximal power tracing, water pump operation, each water pump of system according to wind-powered electricity generation and photoelectricity size cut out automatically, water level management etc. carries out intelligent unified management and control, realized electromechanical integration.
The particularity of Quaternary system system design:
Different with photovoltaic water pump with the pumping water by wind generator of wind power water pumping machine, separate unit blower fan is except will solving above-mentioned key technology, because middle power multiple fan parallel type wind-light complementary water pumping system is to combine by a plurality of subtense angles are scientific and reasonable.Every suit system all also needs to carry out once strict system design according to user's usage requirement and wind energy, solar energy resources situation, makes every suit system can both reach economical and technical benefit the best.
System design has mainly comprised following key Design: function design, matching Design, Redundancy Design, programming, EMC Design, reliability design etc.As will being the water use model that solves process waters such as potable water or irrigation according to the user, the size of water consumption, comprise per day and maximum water consumption, but supply water break time, well depth, water source complementary capabilities etc. are for the user selectes power, lift and the flow of suitable Submerged Motor Pumps and the capacity of wet pit etc.After definite submersible pump model, will be according to local wind energy resources, distribute, do not have continuously the power that effective wind speed fate etc. calculates generated energy and selects wind power generating set as mean wind velocity, wind speed frequency; Select power of suitable solar module or the like according to local solar radiation resource.And correction wet pit capacity.
Because blower fan number, the Model of pump of every suit system all may be inequality, so the frequency variator in the controller, switch power, inverter, programmable controller etc. yet need carry out type selecting and matching Design.Even program software also can be had any different.
