| Abstract: | In petrochemical plants,the starting scheme of large motor directly influences the design of power supply system for the plant.How to determine the starting and control scheme of large motor so as to not only satisfy the technical requirements of superior power grid,but also achieve excellent cost performance and good economic and social benefit is a topic which is worth studying.According to the actual conditions of power grid of petrochemical plants and the technical data of extra-large motor,this paper discusses in detail the starting and control scheme of large motor from modeling calculation to research and determination.It can be used to guide the determination of starting and control scheme for large motor. |
