Method and system for visually displaying historical alarm information in power system

Abstract

The invention discloses a method and system for visually displaying historical alarm information in a power system. The method comprises the following steps: receiving a historical alarm search instruction, and obtaining corresponding historical alarm information according to the historical alarm search instruction; visually displaying the historical alarm information. The visualization display comprises the following step: displaying the respective historical alarm information on factory station / power flow diagrams in a power dispatching automatic system according to equipment information in the respective historical alarm information. According to the scheme provided by the invention, for workers of the power system, the workers are required to read over massive historical alarm information and can directly check states such as alarm sending out condition of equipment in historical events on the factory / power flow diagrams in the power dispatching automatic system, the intuitive visualization display of the historical alarm information in the power system can be realized, and the efficiency is high.

Description

technical field [0001] The invention relates to a display method of historical alarm information in a power system, in particular to a visual display method of the historical alarm information of the power system and a visual display system of the historical alarm information of the power system. Background technique [0002] Alarm is an important content in the power grid dispatching automation system, and it is closely related to the monitoring and discovery of whether the power grid dispatching automation system is faulty by the power grid dispatching automation operator. In the power grid dispatching automation system, alarms mainly include remote signal alarms, telemetry alarms, communication alarms, SOE alarms, operation alarms, etc., and also have different levels to indicate their severity. As the name implies, historical alarm information refers to the alarm information that occurred in the past period of time. By analyzing the historical alarm information, dispatch...

Problems solved by technology

Then, in the dispatching automation system at all levels of the power grid, the historical alarm information is usually massive, and there are many unimportant historical alarm information mixed in it. If each alarm information is displayed to the operator for viewing, it must be a huge deal. volume, resulting in slow processing

Furthermore, for the operators of the power grid dispatching automation system, in their daily work, they are usually not concerned about the specific alarms that have occurred in the system, but need to know the system at a certain time based on these historical alarm information. Based on the current visual display method of historical alarm information, the staff intelligently check each historical alarm information one by one, which has a huge workload and low efficiency.
