Problems solved by technology

The information sources of the system mainly come from meteorological and water conservancy departments, electric power automatic weather stations, and lightning positioning systems. The main information includes: weather phenomena, temperature, air pressure, wind speed, wind direction, precipitation, humidity and other meteorological elements. Measured values, forecast values ​​and historical data ; The early warning method of this system has the following disadvantages: it only provides the service of meteorological elements, and lacks a relatively clear guiding significance for the safe operation of the power grid. It cannot form an early warning for specific electrical disasters, such as galloping, ice disasters, pollution, etc.

Abstract

The invention discloses a power grid disaster early-warning method and system. The method includes the steps of building a corresponding relation of a power grid disaster and routine meteorological phenomena to obtain a power grid disaster early-warning standard, storing the power grid disaster early-warning standard, obtaining weather forecast information of the region where a power grid to be detected is located in real time, comparing the weather forecast information with the power grid disaster early-warning standard to obtain power grid disaster early-warning information of the power grid to be detected, and generating and publishing a power grid disaster early-warning result according to the power grid disaster early-warning information.

Description

technical field [0001] The invention belongs to the field of early warning of meteorological disasters in electric power systems, in particular to a method and system for early warning of power grid disasters. Background technique [0002] Since my country's power grid suffered ice disasters in 2008, the State Grid Corporation has gradually paid attention to the impact of weather warnings on power grid operations. In 2010, it organized and arranged several provincial power companies to try to contact the meteorological department to conduct preliminary research on the weather warning of the power grid. At the same time, in December 2010, it signed a strategic cooperation agreement with the China Meteorological Early warning is an important consideration for the development of power grid security. In this context, power companies in many provinces have built meteorological information early warning systems to varying degrees. Weather element forecast service for several day...
