The Design And Implementation Of Remote Main Station System For Power Grid

As an important part of the power system,power management system is responsible for the monitoring,configuration and early warning of the whole power system,and ensures the stable operation of the system.Power system data,control operation has a certain security requirements,that is,only a small number of people can have access to power management system.At present,when the problems of substation equipment,power operation and maintenance system in some way(SMS,application reminders and other accidents or events)will inform managers,managers according to the event prompt by telephone or other means to convey to the lower management personnel,do to ensure the safety of the power system,but due to the incident need each issued,is not conducive to ensure business continuity of the power system,the basic management can’t master the situation in substation.With the development of Internet technology and WEB technology matures,WEB has been applied to many areas of health,education,electricity,telecommunications and other fields,informatization level is gradually increased,which also makes primary substation companies use Internet technology and equipment of the substation can be real-time monitoring.In order to ensure the security of the system,division of power management system for a plurality of areas,a safety isolating device between regions,and the data for single transmission,namely high security level to the bottom level of regional security area can transmit data,files,and low security zone application only to Gao An level area to send 1 bytes,this to improve the difficulty of real-time data synchronization.This paper realizes the remote operation and maintenance of the master station system based on WEB technology,the Ⅱ system based on a unified data platform,the realization of the two intelligent substation equipment operation status display,through the message push to achieve quasi real time in the control center reflect the running status of the two protection and control equipment.At the same time,the establishment of historical database independent in the Ⅲ District,the Web client should have historical data query functions,for the operation of indicators of health protection equipment to carry out follow-up inquiries,online evaluation of relay protection equipment,real-time reflect the equipment running status in control center,and to prepare for advanced features such as real-time warning.The functions of the system are as follows: monitoring the overall operation of the substation of the basic data graphical display,remote viewing fixed value,real-time display of the event of the event,historical event query display,log storage,easy to check.
