Embodiment 1

[0048] like figure 1 As shown, a wind turbine siting risk assessment method includes the following steps:

[0049] Step 1) Obtain the exact coordinates of the fan information and points to be evaluated;

[0050] Step 2) collecting risk information near the wind turbine point;

[0051] Step 3) divide the total risk R into direct risk assessment R_direct and indirect risk assessment R_indirect;

[0052] Step 4) analyze the point risk R_(location-specific) in the direct risk;

[0053] Step 5) When the resident population within the wind turbine risk impact area is greater than 10, analyze the community risk R_societal in the direct risk;

[0054] Step 6) Discriminate the types of nearby high-risk items according to the nearby risk information collected in step 2);

[0055] Step 7) Select the corresponding risk transfer function according to the type of high-risk articles judged in step 6), and calculate the indirect risk R_indirect;

[0056]Step 8) Add up the point risk R_(l...

Embodiment 2

[0058] A risk assessment method for wind turbine site selection, comprising the following steps:

[0059] Step 1) Obtain the exact coordinates of the fan information and points to be evaluated, the hub height of the fan is 110m, and the blade length is 156m;

[0060] Step 2) Collect risk information near the wind turbine site, and collect that there is a livestock farm within the 1km circular range of the attachment, including 2 long-term residents, a duty room, 1 long-term resident population, and a booster station;

[0061] Step 3) Divide the total risk R into the direct risk assessment R direct and indirect risk assessment R indirect ;

[0062] Step 4) Analyze point risk R in direct risk location-specific , in four steps:

[0063] Step 4.1) The main failure modes of the wind turbine are collapsed tower, blade damage and engine room damage;

[0064] Step 4.2) The annual failure frequency f corresponding to the inverted tower 1 5.8*10 -5 , the number of deaths n 1 is ...

Embodiment 3

[0078] A risk assessment system for wind turbine siting, including:

[0079] The fan information acquisition module is used to obtain the fan information of the wind farm, including the height of the hub, the length of the blade, and the quality, volume and density of each component of the fan;

[0080] The point coordinate acquisition module is used to obtain the point coordinates of the wind turbines of the wind farm;

[0081] The risk information acquisition module interacts with the fan information acquisition module and the point coordinate acquisition module respectively, including a direct risk information acquisition unit and an indirect risk information acquisition unit;

[0082] The direct risk information acquisition unit acquires point information and community information within the wind turbine risk influence range based on the wind turbine information and point coordinates;

[0083] The indirect risk information acquisition unit acquires the risk transfer funct...

Abstract

The invention discloses a fan site selection risk assessment method, system and device and a storage medium, and belongs to the field of wind power plant site selection. Direct risk information and indirect risk information near a fan are obtained through fan information and point coordinates, meanwhile, the direct risk information is subdivided into point risks and community risks, and the indirect risk information comprises danger transfer functions of high-risk article types near the fan. Compared with an existing fan site selection method, the method can accurately evaluate the risk near the fan, has extremely high operability, is suitable for fans installed in different topographic characteristics, and can systematically evaluate the influence of fan site selection points on the human life safety of the accessories. The method helps a wind power plant developer to select a safe wind power plant site, reduces the possibility of wind power plant safety accidents, and provides a basis for reducing the fan site selection risk.

Description

technical field [0001] The invention belongs to the field of site selection for wind farms, and relates to a risk assessment method, system, equipment and storage medium for site selection of wind turbines. Background technique [0002] In recent years, the wind power industry has developed rapidly. Reasonable and effective layout of wind turbines can improve the output efficiency of wind turbines and maximize the annual power generation of wind farms. The site selection of wind farms mainly includes macro-site selection and micro-site selection. The macro-site selection is to determine the location of the wind farm according to the wind energy resources. After the geographical location of the wind farm is established, the specific location of each wind turbine needs to be determined through micro-site selection. The advantages and disadvantages of wind farm establishment mainly consider the utilization rate of wind energy of each wind turbine, the influence of wind turbine ...
