Background technology
Drilling well industry is an operating mode complexity, the industry of high energy consumption, and drill string needs repeatedly during oil-well rig drilling well
Raise and decentralize, need engine to lift drill string wherein above putting forward process, and drill string can then discharge gravitional force in decentralization process, this
A little energy are consumed mainly by brake system.On the electric drive rig that some consider energy regenerating, the gravitational potential of drill string release
Motor can be made to enter power generation operation pattern, the regenerating braking energy of electrical energy form is had been converted into prime feedback.It is universal at present
The energy that only recycling decentralization drill string produces, and have ignored the energy that each tourist bus decentralization produces.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide one kind to be based on ultracapacitor and storage
The energy-storage system and recovery method that battery is formed, can effectively lift well drilling hoist energy recovery efficiency, by under well drilling hoist
The energy regenerating of drill string and empty tourist bus is put, organic efficiency is further got a promotion, has reached more than 70%.
In order to achieve the above object, the technical solution adopted by the present invention is：
A kind of energy-storage system formed based on ultracapacitor and storage battery, including AC network 1, AC network 1 is with using
It is connected in the rectifier 2 for exporting constant direct current, rectifier 2 is connected by dc bus 3 with 4 one end of inverter, inverter 4
The other end by alternating voltage with driving the work drive motor 5 of petroleum drilling machine winch to be connected, between rectifier 2 and inverter 4
Be connected with the control unit 7 of the discharge and recharge for controlling composite energy storage unit 6 on dc bus 3, rectifier 2 and inverter 4 it
Between dc bus 3 on be also associated with braking resistor 8 for consuming energy after 6 saturation of composite energy storage unit.
The composite energy storage unit 6 is made of ultracapacitor and storage battery.
A kind of recovery method of the energy-storage system formed based on ultracapacitor and storage battery, is comprised the following steps；
When transferring drill string, the reversion of work drive motor 5 produces electricl energy, and the electric energy of generation is stored and feeds back to dc bus again
On 3,3 voltage of dc bus is caused to rise, storage battery charges in control unit control composite energy storage unit 6, when storage battery charges
After saturation, then charge to ultracapacitor in composite energy storage unit 6, when ultracapacitor group charges saturation, enable braking electricity
The consumption dump energy of resistance 8, if when 3 voltage of dc bus is higher than maximum voltage threshold, starts 8 consumed energy of braking resistor；
Decentralization finishing drilling column all can above carry empty tourist bus every time, and boring winch is in driving condition, DC bus-bar voltage 3
Decline, control unit 7 controls storage battery in composite energy storage unit 6 to provide energy to it；
When lifting drill string, boring winch is in driving condition, i.e., from 3 draw power of dc bus when, cause direct current female
Line voltage declines, and control unit 7 controls composite energy storage unit 6 to discharge together, when the energy put makes dc bus 3 be less than rectified current
Petroleum drilling machine winch starts the offer voltage of AC network 1 after pressure；
Empty tourist bus can all be transferred after lifting finishing drilling column every time, cause 3 voltage of dc bus to rise, control unit 7
Storage battery charges in control composite energy storage unit 6.
The beneficial effects of the invention are as follows：
By the use of the present invention, the regenerating braking energy that petroleum drilling winch decentralization drill string produces fully has been recycled, it is special
It is not that the energy regenerating of the decentralization to each empty tourist bus store and is used for above carrying for sky tourist bus, not only reduces the ripple of DC voltage
It is dynamic, and organic efficiency is further got a promotion.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
The structural principle to the present invention and operation principle make narration in detail below in conjunction with the accompanying drawings.
As shown in Figure 1：Rectifier 2 is connected with well site power grid, for exporting constant direct current, inverter 4 and rectifier 2
It is connected, by the alternating voltage that DC voltage becomes frequency and voltage can control, for driving the motor of petroleum drilling machine winch.
It will connect, be parallel between rectifier 2 and inverter 4 for storing the composite energy storage unit 6 of energy and control unit 7
On dc bus 3, control unit 7 is used for the discharge and recharge for controlling ultracapacitor group, carries out bi-directional voltage stabilizing output, braking resistor 8
Also it is parallel on the dc bus 3 between rectifier 2 and inverter 4, for consuming remaining energy after ultracapacitor group saturation
Amount.
When transferring drill string, work drive motor 5 generates electricity, when feedback braking energy is increased to the threshold value of brake unit, braking electricity
Resistance forces busbar voltage when dropping to below threshold value, and when voltage rises to the voltage setting value of control unit 7, switch is opened, and is stored
Battery starts to charge up, and after storage battery charges saturation, ultracapacitor group starts to charge up, when ultracapacitor is in charging saturation
Afterwards, stop charging, enable braking resistor 8, consume dump energy.
When above being carried to empty tourist bus, 3 voltage of dc bus declines, and control unit 7 controls electric power storage in composite energy storage unit 6
Tank discharge provides energy.
When raising drill string, motor is in driving condition, and 3 voltage of dc bus drops to the voltage setting of control unit 7
During value, switch is opened, and ultracapacitor lives to discharge into dc bus 3 and comes maintenance voltage stabilization, as energy is reduced, super capacitor
Device group both end voltage can also decline, and after dc bus 3 decreases below rectified voltage always, power grid gradually provides voltage.
When being transferred to empty tourist bus, the rise of 3 voltage of dc bus, control unit 7 controls to be stored in composite energy storage unit 6
Battery charges.
When control unit 7 breaks down, energy-storage system is cut off, from power grid to winch motor homework of supplying power, the system of feedback
Energy is all shed by braking resistor conversion thermal energy consumption.
