Abstract
The utility model discloses an optimized energy saving controller for a combined pumping oil pumping machine, which comprises a DC bus, a frequency controller and a converter, wherein a rectifying energy accumulator is arranged at the input end of the DC bus, a plurality of renewable energy feedback devices are connected in parallel at the input end of the rectifying energy accumulator. When the power on the DC bus is over-higher than the power of the renewable energy feedback device to operate, the rectifying energy accumulator delivers the superfluous electric energy to the frequency controller through the DC bus, the frequency controller is conveyed to the oil pumping machine through the converter, thus the machine halt phenomenon of a frequency changer caused by the overcurrent of the DC bus in the prior art can be avoided. At the same time, because the rectifying energy accumulator conveys the superfluous electric energy to the oil pumping machine, the electric energy saving can be achieved. In addition, because the rectifying energy accumulator can simultaneously control a plurality of frequency controllers, each frequency controller can control each oil pumping machine according to the onsite situation, thus the production output of the oil pumping machine is beneficial to improve.
Description
[technical field]
The utility model relates to a kind of composite type oil pumper that is used for oil exploitation and optimizes energy-saving controller.
[background technology]
The pumping unit that is used for oil exploitation in the prior art has various equipment, wherein uses the most general with beam pumping unit.This oil pumper in use because of oil pumper discharge capacity surplus, makes that idle extraction appears in oil pumper when operation or sky is taken out or the phenomenon of pump dummy status takes place.Adopt the industrial frequency transformer operation to extract oil owing to oil exploitation is subjected to special geographical environmental impact, but in the middle and later periods of exploitation, reserves reduce, motor causes a large amount of electric energy of waste still in operation.In addition, because oil pumper belongs to the potential energy load, especially when the counterweight imbalance,, motor can occur and be in the regenerative braking generating state in the cycle at a stroke of oil pumper work, regenerated energy feeds back to dc bus.Because the dc bus of frequency converter can not be to the electrical network feedback electric energy; can only DC bus-bar voltage be raise to the filtering capacitor charging so feed back to the regenerated energy of dc bus; frequency converter all was provided with protection and shuts down function when DC bus-bar voltage was too high, caused shutdown.
[utility model]
In order to overcome above-mentioned defective, the utility model purpose provides a kind ofly to be avoided causing shutting down phenomenon because of DC bus-bar voltage is too high when the oil field well is exploited and takes place, but also the composite type oil pumper with saves energy is optimized energy-saving controller.
In order to achieve the above object, the technical scheme that the utility model adopted is: provide a kind of composite type oil pumper to optimize energy-saving controller, it comprises dc bus, be connected in parallel on the dc bus or the frequency controller of output and be arranged at transducer on the output of frequency controller respectively, be provided with the rectification accumulator at the dc bus input, on this rectification accumulator input, be connected in parallel to a plurality of Way of Regenerating Energy Feedback devices.
According to above-mentioned major technique feature, described rectification accumulator is connected in parallel by a plurality of diode groups and constitutes together.
According to above-mentioned major technique feature, described Way of Regenerating Energy Feedback device is connected in parallel by a plurality of compound transistor groups and constitutes together.
The beneficial effects of the utility model:, make with the needs of adaptive varying number frequency controller to electric energy because of being provided with the rectification accumulator at the dc bus input; On this rectification accumulator input, be connected in parallel to the Way of Regenerating Energy Feedback device.Press or electric current is crossed the voltage that is higher than the Way of Regenerating Energy Feedback device or electric current and when working automatically, described rectification accumulator is defeated by frequency controller to superfluous electric energy through dc bus when direct current bus bar, frequency controller is transported to oil pumper through transducer.Make and to avoid in the prior art phenomenon to take place because of the DC bus-bar voltage shutdown that frequency converter causes when too high.Simultaneously, because of the rectification accumulator is transported to oil pumper to superfluous electric energy, the feasible effect that can reach saves energy.In addition, because of this rectification accumulator can be controlled a plurality of frequency controllers simultaneously, every frequency controller can be controlled every oil pumper according to field condition can be independently, continuously, regulate the speed, thereby guarantee the normal operation of oil pumper, thereby help improving the output of oil pumper.
[description of drawings]
Fig. 1 is the schematic diagram that the new a kind of composite type oil pumper of this practicality is optimized energy-saving controller;
[embodiment]
Please refer to shown in Figure 1, illustrate that below in conjunction with first kind of embodiment a kind of composite type oil pumper is optimized energy-saving controller in the utility model, it comprises dc bus 1, two frequency controllers 2, two transducers 3, rectification accumulator 4, Way of Regenerating Energy Feedback device 5.
Described rectification accumulator 4 is connected in parallel by a plurality of diode groups and constitutes together.Described Way of Regenerating Energy Feedback device 5 is connected in parallel by a plurality of compound transistor groups and constitutes together.
Be connected with a plurality of Way of Regenerating Energy Feedback devices 5 on the input of rectification accumulator 4, be connected in an end of dc bus 1 at the output of rectification accumulator 4, the other end at this dc bus 1 is connected on the input of frequency controller 2, is connected with transducer 3 on frequency controller 2 outputs.Be parallel with another frequency controller 2 on the dc bus 1 between frequency controller 2 and the rectification accumulator 4, the output of this frequency controller 2 is connected in another transducer 3.
In sum, because of being provided with rectification accumulator 4, make with the needs of adaptive varying number frequency controller to electric energy at dc bus 1 input; On these rectification accumulator 4 inputs, be connected in parallel to Way of Regenerating Energy Feedback device 5.When voltage or electric current on the dc bus 1 are crossed the voltage that is higher than Way of Regenerating Energy Feedback device 5 or electric current and are worked automatically, described rectification accumulator 4 is defeated by frequency controller 2 to superfluous electric energy through dc bus 1, and frequency controller 2 is transported to oil pumper through transducer 3.Make the phenomenon of the shutdown that frequency converter causes when can avoid in the prior art because of dc bus 1 overtension take place.Simultaneously, because of rectification accumulator 4 is transported to oil pumper to superfluous electric energy, the feasible effect that can reach saves energy.In addition, because of this rectification accumulator 4 can be controlled a plurality of frequency controllers 2 simultaneously, every frequency controller 2 can be controlled every oil pumper according to field condition can be independently, continuously, regulate the speed, thereby guarantee the normal operation of oil pumper, thereby help improving the output of oil pumper.
