Alternating Load Loading Controller of Pumping Unit Used in Electric Motor Test

Abstract

The present invention provides an oil pumping unit alternating load loading controller used for a motor test, comprising a measurement simulation system consisting of an oil pumping unit motor, a direct current motor, a torque rotation speed sensor and a DSP electrical parameter measurement and acquisition circuit, and a DSP core control system, wherein the measurement simulation system is characterized in that the direct current motor simulates operating condition of the oil pumping unit to generate alternating load to be loaded to the oil pumping unit motor, and then electrical parameters of the oil pumping unit motor are measured; the DSP core control system controls the direct current motor to generate alternating load by taking the received electrical parameters of the oil pumping unit motor as feedback quantity. The oil pumping unit alternating load loading controller used for the motor test accurately simulates the real operating condition of the on-site oil pumping unit on the premise of ensuring measurement accuracy. The oil pumping unit alternating load loading controller used for the motor test overcomes the deficiency of a conventional oil pumping unit alternating load dynamic loading system, accurately simulates the real operating condition of the oil pumping unit load, and provides practical and effective scientific basis for performance evaluation of an oil pumping unit energy-saving motor.

Description

technical field [0001] The invention relates to an electric appliance and electronic measurement control system, in particular to an alternating load loading controller for a pumping unit used for motor testing. Background technique [0002] The pumping unit is the main equipment for mechanical oil recovery in the oil field. Its power consumption is the main component of the operating cost of the oil production plant. The loss of the pumping unit motor accounts for about 30% of the total loss of the pumping unit well system. In order to reduce the loss of the motor itself, To improve the efficiency of the pumping unit system, many types of energy-saving motors have been introduced in the oil field. There are still some shortcomings in the existing motor test and evaluation methods. Propose an optimization scheme. [0003] There are two main types of implementation schemes for the dynamic loading of pumping units with alternating loads: the simulation of the load on the well...
