| Abstract: | As the loads of oil pump in oil field are changing frequently, a three-phase induction motor that drives the loads often operates under light-load conditions. As a result, the efficiency of the system is low and electric energy is wasted greatly. This paper discusses the possibility of adjusting voltage for the purpose of energy saving, deduces the optimal variable-voltage coefficient and gives a variable-voltage energy saving strategy for the induction motor. The strategy lays a theoretical foundation for efficiency improvement and cost reducing of induction motor in operation. The correctness of the method has been proved by experimental results. |
