Description

Technical Field

[0001] The present invention relates to the field of electric power systems, and in particular to a method and system for managing power grid map data. Background Art

[0002] At present, the power grid map is based on the power grid flow diagram, and appropriately integrates various multi-information diagrams such as geographic information and the external environment of the power grid. It is an important component of the current intelligent control platform. The power grid map is an important visualization and human-computer interaction method in power grid dispatching automation. It is mainly used to display regional power grid equipment information, plant and station line location information, and cross-regional power grid dispatching information. In power grid dispatching, it plays an important role in power grid dispatching visualization, rapid positioning of power grid faults, and power grid dispatching decision analysis. The main technology of power grid map comes from geographic information system (GIS). Geographic information system is a discipline based on cartography and computer. It can analyze and process spatial information and has unique advantages in spatial visualization. Therefore, the design and development of power grid map through GIS can not only intuitively display the real-time operation status of power grid information, but also quickly locate, display and query power grid equipment such as substations, converter stations, power plants, DC lines and AC lines.

[0003] The existing power grid map can only locate, display and query the operating status of electrical equipment in the station, but cannot timely monitor and warn of abnormal conditions of the electrical equipment in the station during operation. Therefore, how to use the power grid map to monitor and warn the electrical equipment in the station has become an urgent problem to be solved. Summary of the invention
