The Development And Application Of Integrated Monitoring Data Processing System For Substation On Basis Of PCS-9700

At present,most substations still use the traditional method of "regular maintenance "to overhaul substation equipment. This method of maintenance is time-consuming and laborious.and the maintenance effect is still disappointing. With the expanding grid,increasing demand for the reliability of the power,today,condition-based maintenance is showing an irreplaceable role.This paper according to the State Grid company variable electric equipment condition-based maintenance work requirements,main for important equipment in the substation to implement online monitoring (transformer,switch,arrester),the workers master equipment condition of run status through online monitoring background at any time in substation.Integrated monitoring data processing system for the substation makes distance monitoring personnel can master all equipments’runing status in the substation at any time to guide overhaul,thus reach the purpose of condition-based maintenance.This topic what based on the NARI company PCS-9700platform, make full use of the mature and emerging on-line monitoring equipment and technology,such as transformer oil chromatography on-line monitoring,transformer partial discharge online monitoring,on-load voltage monitoring of transformer, GIS switchgear on-line monitoring,MOA on-line monitoring technology and the integrated information platform for online monitoring of the equipment,and conduct the monitoring data synthetically,feedback device operating conditions real-time in order to analyse the status of the device,ensure detection the hidden trouble of equipment and exception timely,ensure the safety of the equipment and system.The key technology to the topic is the proper analysis and statistics for various operating equipment,guiding condition-based maintenance work,and ensure the system and equipment in the safe and stable operation.
