Study Of Saving Energy On Controlling Technology By Adjusting Input Voltage Of Electromotor In Water Injection System

A mass of water needs to be injected into the wells because of high level containing water oil fields, so electric energy consuming increased greatly. This is one of the important reasons of short of electric power. So. saving energy in injection system has no time to delay.Based on analyzing many measures of saving energy in water-injectionsystem--technology by adjusting input voltage of electromotor in waterinjection system is chosen to research in this thesis.Pump station can adjust the electromotors' rev according to the practical flux when the method of adjustment rev by adjusting input voltage of electromotor is adopted. This measure can make electromotors run in high efficiency, so that reduces much unnecessary waste of energy. The measure has some advantages such as less cost, adjusting simpleness, maintain convenience, etc. and it has an wide application foreground.Several aspects are studied and some conclusions are got in this thesis: (1) The feasibility of adjusting input voltage to saving energy is analyzed in detail according to theories. It is point out that the adjustment rage of input voltage is not extensive and the best adjusting rage was about...
