Detailed description of the invention
Fig. 1 is the structural schematic diagram of the wind light mutual complementing power supply unit for well head safe control system in the present invention.
Specific embodiment
Below in conjunction with Fig. 1, by preferred embodiment to technology contents of the invention, construction feature, reached purpose and function
Effect is described in detail.
As shown in Figure 1, including for the wind light mutual complementing power supply unit provided by the present invention for well head safe control system:
Wind-driven generator 1, converts wind energy into power output；Solar panel 2 converts light energy into electricity by absorbing sunlight
It can output；Wind/light complementation controller 3 passes through circuit connection with wind-driven generator 1 and solar panel 2 respectively；Battery 4,
Respectively with wind/light complementation controller 3 and well head safe control system 6 by circuit connection, according to the remaining capacity of battery 4, wind
Light complementary controller 3 controls wind-driven generator 1 and/or solar panel 2 and charges to battery 4 or stop charging, and is always
Well head safe control system 5 provides the sufficient electric energy for stablizing safety.
Further, between the battery 4 and well head safe control system 6, also pass through one inverter of circuit connection
5, the voltage which exports battery 4 carries out inversion conversion, and required for exporting it to well head safe control system 6
Applicable voltage or electric current.
In a preferred embodiment of the invention, the inverter is realized using the model of YTP-500, according to well head safe
The DC voltage inversion that battery 4 exports is converted to 220V alternating current, and controlled to well head safe by the power of control system 6
System 6 is powered.
In a preferred embodiment of the invention, the wind/light complementation controller 3 is real using the model of MSP-FG-17019
It is existing.The wind/light complementation controller 3 includes: electric quantity acquisition module, with battery 4 by circuit connection, acquires the current of battery 4
Remaining capacity；First charge switch is arranged between wind-driven generator 1 and battery 4 by circuit connection；Second charging is opened
It closes, is arranged between solar panel 2 and battery 4 by circuit connection；Charge control module, respectively with electric quantity acquisition mould
Block, the first control switch and the second control switch pass through circuit connection.
The charge control module receives the current residual electricity of the battery 4 of electric quantity acquisition module acquisition, and judges
Whether it, which is higher than, overcharges threshold value；If so, the first charge switch of control and the second charge switch disconnect.
In a preferred embodiment of the invention, overcharge the battery capacity that threshold value is battery 4 90%.
The charge control module receives the current residual electricity of the battery 4 of electric quantity acquisition module acquisition, and judges
Whether it is lower than charge threshold；If so, the first charge switch of control and the connection of the second charge switch.
In a preferred embodiment of the invention, the charge threshold is the 30% of the battery capacity of battery 4.
More specifically, when charge control module judges that the current residual electricity of battery 4 is held more than or equal to 4 battery of battery
Amount 90% when, control the first charge switch and the second charge switch and disconnect, wind-driven generator 1 and solar panel 2 stop
It charges to battery 4；When charge control module judges that the current residual electricity of battery 4 is less than or equal to 4 battery capacity of battery
30% when, control the first charge switch and the second charge switch and connect, wind-driven generator 1 and solar panel 2 start to
Battery 4 charges；When charge control module judges that the current residual electricity of battery 4 is greater than the 30% of 4 battery capacity of battery
And when less than 90%, the current state of the first charge switch and the second charge switch is maintained.
After the battery capacity of battery 4 is full of, if continuing for a long time to overcharge it, battery 4 can be caused
Damage, therefore in the present invention, when the remaining capacity of battery 4 is more than or equal to 90%, stop that it is continued to charge in time, to keep away
Exempt to damage battery 4 due to overcharging.
Since when the remaining capacity of battery 4 is less than 10%, charge control module can control battery 4 and stop to inversion
Device 5 exports electric energy, to prevent from causing to damage to battery because of low battery, so as to cause the power-off of well head safe control system 6.
Again since wind energy and solar energy belong to natural energy resources, it can not obtain and generate electricity at any time.So in order to avoid storing
Otherwise battery 4, which is badly in need of charging because of low battery, will lead to power-off, and can not temporarily immediately obtain the extreme of wind energy and solar energy
It happens, the minimum charge threshold of battery 4 is set as 30% remaining capacity by the present invention, to ensure in accumulator electric-quantity
During being reduced to 10% by 30%, there can be the urgent charging time of buffering, to almost can be avoided because of battery 4
Low battery and the case where power off.
Wind light mutual complementing power supply unit provided by the present invention for well head safe control system can obtain wind when simultaneously
When can be with solar energy, wind-driven generator 1 and solar panel 2 start simultaneously at work, and the electric energy being converted to is passed through wind
Light complementary controller 3 charges to battery 4, and after inverter is converted to alternating current, supplies for well head safe control system 6
Electricity.
When can only temporarily obtain solar energy, and can not obtain wind energy, solar panel 2 is started to work, and will conversion
Obtained electric energy is charged by wind/light complementation controller 3 to battery 4, and after inverter is converted to alternating current, is well
Mouth safety control system 6 is powered.
When can only temporarily obtain wind energy, and can not obtain solar energy, wind-driven generator 1 is started to work, and will be converted
To electric energy charged by wind/light complementation controller 3 to battery 4, and be well head after inverter is converted to alternating current
Safety control system 6 is powered.
Therefore, no matter the present invention is not covered by the combination of above-mentioned 3 kinds of working conditions in power grids such as desert, oceans
Area, or the area short in the sunshine-durations such as very long rainy season and winter, can effective guarantee well head safe control system
Power supply abundance stablize safety, to maintain the normal operation of oil recovery gas production production equipment.
In conclusion the wind light mutual complementing power supply unit of the present invention for well head safe control system, it can be abundant
Using natural resources, including wind energy and solar energy, power supply is realized on the spot, and safety is independent, without laying long-distance cable, disposable
Invest it is low, and resource it is renewable, without alternative energy expense generate, to environmental condition require it is low, more cleaning, environmental protection do not pollute
Environment.And it efficient can convert the electric energy that wind-driven generator and solar panel are issued to fill battery
Electricity can avoid the situation of the power supply deficiency because may cause using the single energy, ensureing due to realizing redundancy power generation
Abundance under bad weather and adverse circumstances stablizes safe power supply.
