Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] Such as figure 1 As shown, it is a schematic flow chart of an embodiment of the method for early warning of power grid dispatching operation risk based on weather factors in the present invention, including:

[0022] Step S101: Obtain weather status information including multiple meteorological index data at the location of the power grid dispatching operation equipment;

[0023] The weather status information is information reflecting the current weather status. For example, the weather status information may include one or more of temperature index data, wind speed index data, rainfall index data, visibility index data, relative humidity index data, and lightning risk index data.

[0024] For the temperature index data, the real-time temperature of the area where ...

Abstract

The invention discloses a power grid dispatching operation risk early warning method and system based on a weather factor. The power grid dispatching operation risk early warning method includes the steps of obtaining the weather state information, comprising multiple weather index data, of the location of power grid dispatching operation equipment; subtracting each weather index datum from a corresponding preset threshold value, comparing the difference value with a preset threshold value, and obtaining the weather index value corresponding to the weather index datum; carrying out translation on all the weather index values according to the same translation amplitude, and determining weather index translation values corresponding to the weather index values until all the weather index values obtained after translation are positive numbers; calculating corresponding weather entropies according to the weather index translation values, correcting the weather entropies and obtaining a risk influence value of the power grid dispatching operation on the basis that the current weather factor is the influence factor; carrying out early warning on the power grid dispatching operation under the current weather factor according to the risk influence value. The power grid dispatching operation risk early warning method improves the accuracy of obtaining the risk influence value, and avoids a false alarm in the early warning process.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method and system for early warning of power grid dispatching operation risks based on weather factors. Background technique [0002] With the rapid growth of the scale of the power grid, the AC and DC lines in the power grid are intricate, the number of power equipment is huge, the information of the power grid changes all the time, and natural disasters occur frequently, the factors affecting the dispatching operation of the power grid continue to increase. An important part of risk early warning of power grid dispatching operation is to identify risk sources in the process of power grid dispatching operation, and to quantify and model the risk factors. The risk source will affect the power grid dispatching operation, so the corresponding risk impact value can be generated. The greater the risk impact value, the greater the risk to the power grid dispatching operation....
