Abstract

The invention discloses a system and a method for monitoring and warning disasters of power grids on the basis of a GIS (geographic information system). The system comprises a data acquisition unit, a control unit, an information transmission unit and a centralized control center. The data acquisition unit comprises a satellite monitoring module and a monitoring module with a monitor, the centralized control center comprises an industrial control computer and a display, a warning module, a database module and a GIS module are arranged in the industrial control computer, the industrial control computer is used for displaying monitored information and carrying out warning for environmental change, and the database module is connected with the GIS module. The system and the method have the advantages that running conditions and environments of the power grids can be monitored by the aid of the fixed-point monitor for circuits of the power grids and photos shot by satellites, the monitored information is imported into the GIS, and accordingly the power grids can be visually monitored in real time; historical natural disaster accident information and pre-accident environmental information change can be imported into the system, accordingly, monitored data can be predicted, staffs can prepare for the disasters of the power grids in advance, and loss due to the disasters can be reduced.

Description

technical field [0001] The invention relates to the technical field of remote monitoring of power systems, in particular to a GIS-based power grid disaster monitoring and early warning system and method. Background technique [0002] Electricity is the pillar energy and lifeline of the country. At the same time, because most of the power grid system is directly exposed to natural conditions, it is greatly affected by environmental factors and natural disasters. The occurrence of various natural disasters often directly threatens the safe operation of the power grid system, and even causes serious power grid damage and large-scale power outages, which in turn affects people's normal production, life and social stability. With the continuous deepening of the intelligent development of the State Grid, the large-scale construction of the UHV transmission network, and the large-scale and high-efficiency power grid marked by large-scale networking and large-capacity encounter disa...
