Research And Application Of Condition-based Maintenance Management Of Protective Relays In Shenzhen Power Supply Bureau

The social quality of electricity services have become increasingly demanding,inside t he power supply enterprise also has a downsizing to im prove efficiency requirements,in this environment,the drawba cks of traditi onal mai ntenance management mode becom e realized.In recent yea rs the development of technology,especially the rapid development of computer t echnology,microelectronic t echnology,communicat ions technology and other technology,relay protect ion equipment condition-bas ed maintenance work can be car ried out..Relay protection and automatic safety devi ces need to ensure that in the event of a grid failure can be fast,reliable,sel ective action,in order to ensure that the grid s tronger,m ore sel f-healing,more secure,and thus avoid like foreign power sys tem,occur bl ackout,whi ch relay protection equi pment operation and maintenance work the need for new initiatives.C o.,Ltd.Shenz hen Power Supply Bure au protection devi ces for the study,the combination of the characteristics of the protecti on devices,contact the production of the actual work,absorbing domest ic and foreign advanced ex perience of the condition-bas ed maintenance work,detailed study of relay protecti on equipment condition-bas ed maintenance st rategy.First introduced the S henzhen Power Supply Bure au Lim ited protection devices maintenance management of the status quo,the problems of the current maintenance mode;then summarized the current protection devices online monitoring tools;Co.,Lt d.S henzhen Power Supply Burea u relay the device status evaluation and ris k assessm ent model,the application of evaluation methods to quantify the amount of relay protection status to avoid the drawbacks of the previous qualitative evaluation equipment.Finally,t he paper collection of defect data protect ion device is analyzed and compare d the occurrenc e of defects before and after the implement ati on of condition-based maintenance,protecti on devices,the specific data that the effect of the i mplementat ion of condition-based maintenance is very obvious to improve t he stability of the relay prot ection equi pment the ability to run,thereby ensuring a reliable grid operation.
