The Transformation Of Integrated Automation System In 220kV Substation

Substation as the hub of power grid,is will power(power plants)transmission of electricity to power a central part of the user.Power system can reliable and economic operation is decided by its running situation.In view of the traditional transformer substation of the deficiencies and shortcomings,and can't meet the demand of nowadays grid of the status quo,put forward to automation,computer and communication technology application in substation.In this paper,the operation years of shelong including 220 kV substation as an example,presents the concrete scheme and measure substation integrated automation.First summarizes the research and application of integrated automation system at home and abroad,introduces the structure of substation integrated automation system of the existing several common,by comparing the advantages and disadvantages of traditional and integrated automation substation transformer substation,expounds the necessity of old substation integrated automation technology renovation.By looking at substation original records and information provided by the equipment manufacturer,to a secondary equipment within the station of the status of the investigation and analysis,combining with advanced technology and economic rationality for reforming the premise,according to the working status of substation now,after the principles of transformation and upgrading is going to achieve,formulate reasonable technical transformation scheme.Including on the replacement of an old equipment,mainly introduced the reconstructive HuanXing relay protection device and the computer monitoring and control system of equipment configuration.In addition,for the new access system,the optical fiber protection device,optical fiber channel,the performance of the measurement and control device,has also been detected,which can ensure the normal operation of the system and perform the functions of the system.By providing shelong after transforming the substation operation parameters compared with the condition of a few years ago,shows that the integrated automation retrofit scheme to achieve the expected goal.Through the introduction of substation accident,the station's integrated automation system how to assist the operational staff to identify the fault location,and gives the failure analysis,and then quickly to deal with the accident.This strongly confirms the substation integrated automation system can not only can improve the quality of transmission of electricity,but also can improve the operation of the substation level and management level.
