Description
Technical field
The utility model relates to oil well production technical fields, mutually present control more particularly, to DC bus oil well team control frequency conversion
System.
Background technique
In modernization development process, oil well collection control production management system is also more and more intelligent, and existing oil well collection control is raw
It produces in management system, there are allocation plans as shown in Figure 1, that is, WEB server, gang of wells monitoring including successively communication connection
Database server, wireless telecommunications management system, and each pumping unit module includes that terminal called Transmit-Receive Unit, electricity data are adopted
Collect unit, terminal frequency conversion control unit, terminal protection unit.
Wherein, pumping unit and driving unit are directed to, various detections in relation to pumping unit and driving motor domestic at present and
Control mode is varied, such as: 1, it is the inversion speed-governing that pumping unit is equipped with for the purpose of improving technique, improve recovery ratio
Device, indicator diagram measurement analyzer, slip electric motor, pole-changing control；2, for pumping unit due to being chronically at " low load with strong power " shape
The problem that effect caused by state is low, power factor is low, the Energy Saving Control motor used in order to energy-saving, decompression energy conservation and A/
The control of Y connection, and energy-efficient so-called energy-saving device etc. is realized by intermittent control to pumping unit.
Foreign countries mainly use fairly perfect Converse speed regulation apparatus and matched indicator card around the control of pumping unit
Measuring and analysing meter etc. can not only better meet the requirement of DP technology by inversion speed-governing device and multifunction control system, but also
Effective energy saving purpose can be reached.
The inversion control cabinet that each oil field uses at home has difference and influence in technology and performance in following several respects: first
First, one hand over inverter structure always as handing over, hand over the circuit structure for rectifying and filtering link always different, for net side power because
Several sizes and there is direct influence to the harmonic pollution degree of power grid.Secondly, SPWM control and pressure regulation for inversion link
The algorithm of control is different, directly affects the decompression energy-saving effect under realization pumping unit " low load with strong power " state.Again, inversion
Usually there are two types of different processing modes and configuration configuration for uneven energy regenerative of the control cabinet to pumping unit: first is that accessing in DC side
Brake resistor energy consumption, circuit are simple and easy；Motor is fallen to send out using PWM Reversible Rectifiers second is that handing over and rectifying and filter link always
Electric flux feed-in power grid, enables uneven energy regenerative to recycle, avoids energy waste.Latter techniques' difficulty is larger, cost also compared with
It is high.Further, since used technological means is different, control cabinet cost is also different, but totally apparently, inversion control cabinet
On the high side, each oil recovery factory is difficult to receive, this is also that inversion control cabinet is difficult to the main reason for large area is widely applied at present.
Therefore occurs " the pumping unit gang of wells based on DC bus such as Authorization Notice No. for CN202679286U in the market
This kind of technology of control system ", should rod-pumped well group control system based on DC bus include: transformer, it is straightening and filtering unit, more
High-voltage electricity is reduced to 380V or mesohigh three-phase alternating-current supply by a inversion terminal control unit, transformer, and straightening and filtering unit will
Three AC power sources are converted to direct current energy, which is converted to AC energy, is by multiple inversion terminal control units
Multiple pumping units provide the AC energy, and monitor, control in real time to the operating condition of the inversion terminal control unit.
It is poor, at high cost etc. to solve existing equipment effect for the above-mentioned this kind of rod-pumped well group control system based on DC bus
Problem has energy-saving efficiency high, low cost, can prevent DC bus-bar voltage fluctuate widely and over-voltage, and can be realized
The advantages of the transmitting electricity of not boosting of relatively remote " one drag more " oil well.
But it is installed outdoors based on the inversion terminal control unit in above-mentioned technology, and due to the voltage in the controller more
Higher than the ceiling voltage that human normal can bear, therefore operator is before the cabinet door for opening the controller cabinet body, in order to pacify
For the sake of complete, operator generally requires first to take insulating glove.But in actual mechanical process, usually there is operator and forget to carry absolutely
Edge gloves, and need to return and take the case where could operating to cabinet body and the intracorporal component of cabinet after gloves, then very not
Just.
