Abstract

The energy-saving effect of Y/Δ change-over controller is better than the silicon controlled rectifier(SCR) voltage regulating style when the load rate of oil-pumping unit is low; but the silicon controlled rectifier(SCR) voltage regulating style is better than the energy-saving effect of Y/Δ change-over controller when the load rate of oil-pumping unit is high. Based on high-precision three-phase electrical energy measurement IC-ATT7022A, a new energy saving controller of combining the advantages of both controllers is designed. On the analysis of based on the principle of voltage regulating and energy saving of electric motor of pumping units. This paper analyzes the system´s hardware and software design. Through the installation of Y/Δ-SCR controller and comparison tests at the scene in five oil wells, every well saves 21000 kW.h annual.
