Regional power grid environment risk assessment method

Abstract

The invention discloses a regional power grid environment risk assessment method, and relates to the technical field of power grid planning, and the method comprises the following steps: selecting a target regional environment according to an actual demand, and making a planning scheme; obtaining environment risk related information of the target area, constructing a comprehensive environment risk assessment index system of the target area, and constructing a risk assessment model according to the index system; determining the weight of each index in the risk assessment model; and carrying out grading quantification according to the indicator system to obtain an environment risk value of the target area. According to the regional power grid environment comprehensive risk assessment method, on the basis of the environment data, the power grid planning environment influence key factors are identified, the corresponding risk levels are assessed, the power grid planning environmental impact evaluation and the power transmission and transformation project are effectively combined, the planned substation site selection and line selection can be optimized, the environmental risk can be fully identified and avoided, and the environmental dispute and emergencies can be prevented and reduced.

Description

technical field [0001] The invention relates to the technical field of power grid planning risk assessment, in particular to a regional power grid environmental risk assessment method. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network, or power grid for short. It includes three units of power transformation, power transmission and power distribution. [0003] With the development and progress of the society, the current power grid construction has become the main direction of China's electric power construction. The prospect of power grid construction is very attractive. During the construction of the existing power grid, the site selection of its substations and line selection need to be adequately planned. , therefore, environmental risk assessment has become an indispensable part of power grid construction.

Problems solved by technology

[0009] The above method analyzes the risk distribution of the transmission line section based on the comprehensive consideration of environmental factors and terrain characteristics, and designs the corresponding multi-risk section division of the transmission line and the risk level assessment method of the tower to provide an evaluation basis for the refined operation and maintenance of the transmission line. However, This method still only conducts a single risk assessment based on the topography of the target area, and its assessment effect is not good, and it cannot guarantee that the power system will not be disturbed by other risk factors in the later stage
