Research on EMS Alarm Analysis and Secondary Equipment Status Evaluation

[摘要] The intellectualization level and information level of the secondary equipment in the intelligent substation have been greatly improved, which is of great significance for the normal operation of the power system. However, the secondary equipment will generate a lot of redundant alarms information in the EMS system. These alarms are not conducive to finding equipment faults, and there is a lack of an active maintenance method for secondary equipment. In this paper, an intelligent analysis method of EMS alarm information is proposed. This method can find fault alarm information accurately, and we used the actual data of intelligent substation to verify it. A status evaluation method for the secondary equipment is also proposed. The method can be used for early warning of equipment failure and efficient operation and maintenance.
