Description
Technical field
The invention belongs to a kind of intelligent electricity-saving control system, specifically a kind of intelligent electricity-saving control system of balance beam type oil pumping machine of using the intelligent fuzzy control technology.
Back of the body border technology
Low energy, stripper field for hyposmosis, most of oil field will lean on water filling to press oil to go into well, with oil pumper oil is elevated from the stratum again, changing oil or change oil with electricity with water is the reality in this oil field, thereby, the electricity charge have accounted for sizable ratio in the cost of oil production in this oil field, so petroleum industry is attached great importance to saves energy.
At present, the power-saving technique for oil-field oil pumper does not still have the power saving apparatus that performance is reliable, power savings is obvious, economical and practical.Be used for the power saving apparatus on the oil pumper, requirement is that rotating speed is constant, throughput rate can not reduce, but existing frequency converter power-saving technology is not suitable for using, because which can cause the decline of oil offtake, the method as by the reactive-load compensation economize on electricity has also just reduced the distribution line loss, also have by the economize on electricity of frequently switching method of Y-Δ, also have very big drawback.Also have take timing mode between take out control, but this to take out control be time control purely, need be determined empirically the time, random big, operability is low.
Summary of the invention
The objective of the invention is to work out a kind of intelligent electricity-saving control system of balance beam type oil pumping machine.
The energy-saving effect that the existing oil pump energy-saving system that the present invention will solve exists is poor, the problem of control trouble.
Technical scheme of the present invention is: it comprises single-chip microcomputer; the detecting signal unit that is connected with single-chip microcomputer; be connected with the controllable silicon unit on the single-chip microcomputer; between take out control module and harmonic wave and suppress energy feedback unit; detecting signal unit is used to detect the current value of motor; supply voltage; the pressure signal of pressure transducer; the water yield signal of water content sensor; the temperature signal of temperature sensor and the phase zero points of power supply; then these signals are sent into single-chip microcomputer; by the single-chip microcomputer analyzing and processing; take out control module between again the phase shift trigger pip after handling being sent into; by a phase shift triggering of taking out the command signal control controllable silicon unit of control module; between take out control module function be that correlation parameter is carried out Fuzzy Calculation and constantly self study; accurately judge down-hole liquid level rule situation and carry out automatic startup-shutdown; harmonic wave suppresses energy feedback unit; its function is to suppress the effect of harmonic wave, reduces electric motor overheating; prevent the radio interference.
Advantage of the present invention is that power savings is good, simple to operate, control is convenient.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in the figure; the present invention includes single-chip microcomputer; the detecting signal unit that is connected with single-chip microcomputer; be connected with controllable silicon unit thyristor module on the single-chip microcomputer; between take out control module and harmonic wave and suppress energy feedback unit; detecting signal unit is used to detect the current value of motor 2; supply voltage; the pressure signal of pressure transducer; the water yield signal of water content sensor; the temperature signal of temperature sensor and the phase zero points of power supply; then these signals are sent into single-chip microcomputer; by the single-chip microcomputer analyzing and processing; take out control module between again the phase shift trigger pip after handling being sent into; by a phase shift triggering of taking out the command signal control controllable silicon unit of control module; between take out control module function be that correlation parameter is carried out Fuzzy Calculation and constantly self study, accurately judge down-hole liquid level rule situation and carry out automatic startup-shutdown.Harmonic wave suppresses energy feedback unit, and its function is to suppress the effect of harmonic wave, reduces electric motor overheating, prevents the radio interference.Controllable silicon unit thyristor module has three, contains the unidirectional thyristor of two reversal connections each other in every.
Be connected with auxiliary reclay and telltale on the single-chip microcomputer, controllable silicon is connected with fastp-acting fuse on the unit, be connected with pressure transducer, water content sensor, temperature sensor, current sensor, zero phase testing circuit on the detecting signal unit, single-chip microcomputer is provided with master controller, is provided with A/D converter and code translator in the single-chip microcomputer.
Also be connected with the auto by pass system on the single-chip microcomputer, its function is when single-chip microcomputer breaks down, and power supply is directly powered and given motor 2.Single-chip microcomputer takes the sampling rate with 500 times/second to read motor 2 service datas.Also be connected with hummer 3 on the single-chip microcomputer, motor 2 links to each other with oil pumper 1.
Electricity principle of the present invention is to start to control angle α by controllable silicon unit thyristor control, reduces motor 2 voltage effective values and reaches energy-conservation purpose.When motor 2 is operated in little torque section, load torque hour just, the present invention promptly detects the signal that electric current reduces, angle phi increases, Cos φ reduces and reacts at once, pilot angle α is increased, conduction angle descends, the voltage effective value that is added on motor 2 is descended, thereby reduce the unloaded active loss and the reactive loss of motor 2 greatly.The variation relation of motor 2 efficient and Cos φ is seen Fig. 3, P among Fig. 3
2Be motor 2 output powers; η
1And η
2Be respectively the efficient after total head and the step-down; Cos φ
1With Cos φ
2Be respectively the power factor after total head and the step-down.Simultaneously, take out control module for of the present invention motor 2 is carried out automatic start-stop control, do not have oil, thereby fundamentally eliminated because the invalid extraction that the empty phenomenon of pump is caused with regard to stop pumping, so also both reached significant power savings, and prolonged mechanical equipment life again.
