Description
Technical field
The invention belongs to electric submersible pump VFC field, be specifically related to a kind of electric submersible pump oil pumping system order and open
Machine control method.
Background technology
Electric submersible pump oil recovery technique has that lifting efficiency is high, take up an area less, invest little, energy consumption is low, the advantage such as steadily that goes out liquid,
So being widely used in oil field.But bigger starting current can be produced on startup due to submersible electric machine with oil, one
As be 5-10 times of Ie, not only motor and institute's bringing onto load equipment are caused and electrically and mechanically damage, and electrical network electricity can be caused
Drops, the miscellaneous equipment affecting same electrical network runs.
In order to avoid when ensureing electric motor starting that the operation of same other electrical equipment of electrical network is impacted, would have to increase
The capacity of big mains transformer.If in well site, some submersible electric machine with oils start, then be accomplished by the transformation of more capacity simultaneously
Device.As can be seen here, if multiple stage electric submersible pump starts simultaneously, electrical network can be caused punching greatly by the huge starting current of generation
Hit, and the transformator choosing more capacity also will increase initial investment and power consumption.
Summary of the invention
The technical problem that the starting current that brings to solve multiple stage electric submersible pump to start simultaneously is excessive, the present invention provides
A kind of electric submersible pump oil pumping system order opens machine control method.
The technical solution of the present invention is: a kind of electric submersible pump oil pumping system order opens machine control method, and it is special
Part is: comprise the following steps:
1] initialize after oil pumping system and control system power on；
2] by local monitoring system or distant station Ore-controlling Role, preset value is write in core controller；
3] the manual/auto state of an electric submersible pump is read；If being in manual mode, then continue to read next electricity
The manual/auto state of dynamic oil-immersed pump；If being in auto state, then perform step 4]；
4], after receiving startup order, start electric submersible pump and pump, gather the output electric current of converter simultaneously；Wait to become
Frequently after the output electric current of device tends towards stability, step 5 is performed]；
5] repeated execution of steps 2-4], until all of electric submersible pump being in auto state all completes to start.
Step 2] in preset value include the predetermined power of motor, preset rated current and default rated speed.
Step 4] in startup order sent by local switch board, local monitoring system or distant station Ore-controlling Role.
Step 4] in output electric current directly read from converter by MODBUS agreement by core controller.
It is an advantage of the current invention that:
(1) present invention carries out sequentially opening machine by controlling electric submersible pump oil pumping system, changes electric submersible pump random
The present situation started, it is entirely avoided the problem that multiple stage electric submersible pump starts simultaneously, reduces the starting current impact to electrical network.
And the present invention controls just to carry out next electric submersible pump after the motor operating current of an electric submersible pump reaches stationary value
Startup, it is to avoid interfere, it is ensured that each electric submersible pump stable.
(2) the electric submersible pump oil pumping system order using the present invention to provide opens machine control method can be with supporting low capacity
Transformator, reduces initial investment and power consumption.
Accompanying drawing explanation
Fig. 1 is system structure schematic diagram used in the present invention.
Detailed description of the invention
It is based on the control system shown in Fig. 1 that the electric submersible pump oil pumping system order that the present invention provides opens machine control method
Realize.
First, assembly and the connection of each equipment is completed according to the system structure in Fig. 1 and the mode of connection.
Then, use following steps to carry out the order of electric submersible pump oil pumping system and open machine:
Step 1: oil pumping system and control system initialize after powering on；
Step 2: read the power of motor value of every screw pump set in advance, the load current value of motor, Rated motor
Tachometer value.Value set in advance arranges core controller ICU by local monitoring system HMI or backstage distant station Ore-controlling Role
In.
Step 3: read the manual/auto state of an electric submersible pump, if being in auto state, then enters step 4；
If being in manual mode, then repeated execution of steps 3, read the manual/auto state of next electric submersible pump.Electric submersible pump
Manual/auto state be directly entered the DI port of core controller by terminal.
Step 4: receive after starting order, starts electric submersible pump and pumps, gather the output electric current of converter simultaneously；
After the output electric current of converter tends towards stability, after i.e. output electric current is more than presetting rated current, perform step 5.Start order
" startup " button in button, or local HMI, or " opening in distant station Ore-controlling Role " can be started " by this cabinet door
Dynamic " button is controlled.
Step 5: repeated execution of steps 2-4, until all of electric submersible pump being in auto state all completes to start.
After oil extraction operation terminates, by " stopping " button in " stopping " button, or HMI of local switch board panel,
Or " stopping " button in distant station Ore-controlling Role, sends and ceases and desist order.ICU receive stop after ceasing and desisting order all electronic latent
The operation of oil pump.
