An 110KV Substation Project Of Jilin Oilfield Power Supply Company

The substation is an important part of power system,is from the power plant electricity voltage change processing places,long-distance transmission needs to turn to the high voltage,and the normal power supply to nearby users need to change to low voltage,this voltage change requires complete substation.China oil Jilin oilfield company belongs to Chinese Petroleum Group,located in the northwest of Jilin Province,the company set up in the office in Ningjiang district of Songyuan City,oil is in the rising period,with a larger space for development.Substation design in accordance with the requirements of Songyuan development planning,combined with the characteristics of the project,construction scale,determine the future development plan,take the overall plan,select the best design plan.The equipment used in the substation design needs to meet the relevant national and industrial standards and ensure its economy and energy saving.This paper mainly designs the 110 KV transformer station of Jilin oilfield power supply company.First,analysis of China's substation and substation design trends,according to the substation design task,combined with the basic data,the design requirements and load analysis,to ensure safe and reliable operation of the substation process,and reduce the design,construction and operation cost as much as possible.Short circuit current is calculated to serve as the basis for the design of subsequent electrical equipment and other devices.According to the results of load and short-circuit current,to determine the parameters of the main transformer,and then check the relevant electrical equipment,determine the distribution equipment application of substation operation,at the end of the lightning protection and grounding protection and reactive compensation device are analyzed.Through the design of 110 KV substation of Jilin power supply company,the comprehensive automation system is applied to improve the work efficiency of the substation,and it can also meet the demand of nearby users and improve the quality of power supply.
