Description
Technical field
The invention belongs to power technique fields, more particularly relate to the design of used for oil extractor wind power generation and the electric commplementation power supply source of net.
Background technology
The oil pumper in oil field is all powered with the electric energy of AC network at present.Because oil field self, hundreds of even more oil pumpers extensively are distributed on the vast field, and transmission line is long, and power consumption equipment distributes and very disperses the consume significant of electric power.Because of transmission line is long, power consumption equipment disperses, power supply expense, administration fee and the expenses of environmental protection of electric power is just high; And very easily usurped by the unprincipled fellow.Cause is with mains-supplied, and the consumption of electric power is big again, and cost for oil production is inevitable high; And, in case grid power blackout certainly will influence the production in oil field; In addition, along with the rise of burned coal price, the expense of power consumption also can further improve.
Wind resource on the field is quite abundant in fact, with wind power generation and the complementary power supply of net electricity, should be the even more ideal electric energy scheme of oil-field oil pumper.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of wind power generation and civil power complementation are provided, make motor utilize the wind energy energy-saving run, production cost is low, helps environmental protection, difficult quilt is stolen, and used for oil extractor wind power generation that can uninterrupted power supply and the electric commplementation power supply source of net.
In order to achieve the above object, parallel wind-driven generator and the AC network of inserting of the present invention.One or more threephase switch that has that inserts electrical network in parallel, the output of each road threephase switch connects one road ac/dc inverter, the dc output end of each road ac/dc inverter connects one road DC/AC inverter, and the three-phase alternating current output of each road DC/AC inverter connects load through a threephase switch.One or more threephase switch is connected with the output of wind-driven generator in addition, the output of this threephase switch connects a three-phase rectifier separately, the dc output end of each road three-phase rectifier connect separately a diode, the dc output end of incoming transport/direct-flow inverter then.
Charger that also has that inserts electrical network in parallel.This charger connects batteries through dc switch, and another utmost point of batteries is connected through the dc output end of a rectifier diode with each road ac/dc inverter.
The dc output end of each road ac/dc inverter connects a DC/AC inverter, and the three-phase alternating current output of DC/AC inverter connects load again, constitutes an inversion unit.
The dc terminal of each road DC/AC inverter also is connected with remote monitor with the RS485 interface through gatherer.Each inversion unit is by gatherer and RS485 interface, the long-range remote monitoring monitor of passing to of situation with the oil pumper operation, the remote monitoring monitor can stop by the switch of every equipment of this interface control, and can observe the operation conditions of every equipment by computer.
The present invention is work like this: when wind energy, the AC energy of wind-driven generator becomes direct current energy through three-phase rectifier with AC energy.Meanwhile, the AC energy of electrical network also becomes direct current energy through the ac/dc inverter.Be that three-phase alternating current is exported to load through the DC/AC inverter inversion again.Because becoming the voltage of direct current energy, wind energy is higher than the direct current energy voltage that the net electricity becomes, so when powering load, preferentially use the power supply of wind energy electric energy.
When wind energy was not enough, the direct voltage of wind energy descends, and was consistent with the net piezoelectric voltage, nets electric energy and gives supplementary power.
During no wind energy, the dc voltage of netting electric inversion is higher than accumulator battery voltage, serves as main power supply to net electricity then.When no wind energy and there be not when electricity net, the electric energy of batteries continues to keep the power supply of certain hour.
After the net electricity recovered, the net electricity powered to the load on the one hand, netted electric energy simultaneously through the charging of charger accumulators group, and electrical power storage is got up.When wind energy again sometimes, then recover wind-powered electricity generation power supply.
Each inversion unit of the present invention directly links to each other with an oil pumper, can independently close to stop and variable frequency starting, or the wobble frequency operation, press the electricity-saving power supplying mode operation.Each inversion unit can be as required becomes direct current energy for the sine wave or the output of quasi-sine-wave electric energy of frequency conversion or not frequency conversion gives electric.If installing oil production additional, every oil pumper uploads signal, can be with the oil pumping data of every equipment, and collection analysis such as electrisity consumption report, and are convenient to function expansion.This device is except that wind-driven generator, and other member such as rectifier, charger, battery, inversion unit all can be placed in the same rack, can be than long distance power transmission, and be convenient to centralized management and safeguard.
The present invention is actually a kind of complementary energy-conservation power-supply controller that is connected between wind-powered electricity generation, net electricity and the motor of oil extractor.With the wind-powered electricity generation power supply, when wind-powered electricity generation is not enough, replenish generally speaking to net.
The electric energy that the present invention produces based on wind power generation as replenishing, can carry out 24 hours uninterrupted power supply with the electric energy in the electrical network to the some oil pumpers in oil field simultaneously.In the moment of wind energy with net electric energy conversion or complementary process, interruptedly supplying power does not take place in this device, and transfer process switching time is zero.When no wind energy, net electricity sudden power or when having a power failure, the storage battery among the present invention can be converted to alternating current with direct current energy immediately, powers incessantly, and can guarantee to continue power supply at 20～30 minutes again.When net electricity or wind-powered electricity generation restored electricity, the present invention can recover to net electricity or wind-powered electricity generation power supply immediately.The present invention also can adopt man-to-man conversion power supply to oil pumper in whole electric power system, this scheme can make this electric power system economize on electricity 20～25% on the basis of former power consumption.Also can require varying frequency starting and conversion power supply, make the rotating speed requirement of suitable each oil well better of oil pumper each pump load.Also can be electric submersible pump frequency conversion and uninterruption power source are provided, solve electric submersible pump power failure fault and direct problem such as startup difficulty.
The present invention can realize remote monitoring, the control cabinet of motor is left concentratedly in 500 meters radius managed concentratedly.Because of changing frequency of supply, in power supply process, can prevent to steal electric energy.
It can be widely used in the power supply of the equipment that oil pumper etc. is remote, large tracts of land distributes in oil field.
