Method for generating power system polluted region distribution map by utilizing intelligent rule base engine

Abstract

The invention discloses a method for generating power system polluted region distribution map by utilizing intelligent rule bank engine. An intelligent rule bank is divided into a pollution source rule bank, a pollution level rule bank, a pollution wet characteristic rule bank and an operating experience rule bank, quantization is carried out on each rule attribute, attribute information of region characteristic and weather characteristic of each rule are assigned, various data is input, an automatic map forming intelligent rule bank engine is built by virtue of GIS buffer area algorithm and GIS modelling technique, a thematic map of each rule bank is generated by applying GIS buffer area algorithm and combining weather data, each thematic map is subject to superposition according to GIS modelling technique, and GIS fusion algorithm is adopted to fuse corresponding map layers, and then each pollution level map layer is spliced, thus finally generating the polluted region distribution map. The method has the advantages that drawing efficiency is high, polluted region information can be updated and shared at any time, operating experience and drawing rule can be quantized and intellectualization degree is high.

Description

technical field [0001] The invention relates to a method for generating a power system polluted area distribution map by using an intelligent rule base engine. Background technique [0002] The power system pollution area distribution map is a zoning map of the degree of influence of the external insulation of high-voltage overhead lines and electric porcelain in power generation and substations on the external insulation strength due to natural pollution. It is the basic basis for guiding the design and configuration of external insulation of power transmission and transformation equipment. The basis for production, operation and maintenance is also a bridge for communication between design, construction and production departments, and it guides power transmission and transformation equipment in the power grid, continuously improves the anti-pollution flashover capability of the power grid, and regulates the external insulation configuration of new power transmission and tra...

Problems solved by technology

[0010] 1) It takes a lot of manpower, material resources and quite a long time to draw such a map of the distribution of contaminated areas

[0011] 2) The information of this type of polluted area map cannot be updated, and the drawing of the polluted area map of the small power grid and the polluted area of ​​the upper-level grid and between the grids of the same level is independent of each other, and data sharing cannot be realized

Moreover, the revision work is difficult, and it can only be revised uniformly every few years, so it still cannot reflect the real-time pollution situation in the area in time.

[0012] 3) The drawing rules cannot be quantified and intelligentized, and it is difficult to analyze comprehensive factors such as geography and weather for each rule. The drawn pollution area map often relies on the experience of the drawer
