| 摘要 |
The present invention is concerned with alarms of a Process Control PC system for an industrial plant described by a standardized or formal system configuration description, in particular alarms of a Substation Automation SA system for a substation in a high or medium-voltage power network. The alarms are embedded in an automated way into a sum alarm for further processing or analysis. All alarms are identified and retrieved from the system configuration description and assigned to a plant or structural level according to the configuration description. Based on an alarm type, such as a Logical Node class and Data Object name according to IEC 61850, likewise retrieved from the system configuration description, and according to some preconfigured or user-defined rules, each identified alarm is assigned to an alarm category. Finally, sum alarms at a particular plant level and per alarm category are derived from all alarms assigned to the respective alarm category and all plant hierarchically lower plant levels. |
