In practical application, the generating efficiency of the wind power plant depends on the abundance degree of wind energy resources, so the macro site selection and the micro site selection of the wind power plant are very important. The macro site selection of the wind power plant is a process of determining the site of the wind power plant by comparing and analyzing wind energy resources and other construction conditions of different areas in a larger area. After the site of the wind farm is determined by macro site selection, it is necessary to arrange wind turbines in the field area of the wind farm to ensure maximum efficiency in utilizing the wind energy resources in the area, which is the process of micro site selection.
Technicians commonly use a Geographic Information System (GIS), which is a technical system for collecting, storing and managing geographic data related to the whole or part of the space of the earth surface layer (including the atmosphere) under the support of a computer software and hardware system, to realize the design and micro-site selection of wind power plants. Technicians can simulate on-site micro site selection on a wind power plant model of a GIS system. After a technician designs an air outlet electric field scheme, the feasibility of the wind power plant design scheme needs to be evaluated, or a plurality of schemes need to be compared and analyzed, and a scheme meeting the expectation of the technician is selected. Therefore, the embodiment of the application provides an evaluation method of a wind power plant design scheme which can be applied to a GIS (geographic information system) and is used for assisting technicians in micro-site selection and layout design of a wind power plant.

Referring to fig. 2, the following description is given to wind farm design information and evaluation information in the embodiment of the present application by way of example, and an embodiment of an evaluation method for a wind farm design scheme in the embodiment of the present application includes:
201. the geographic information system obtains a three-dimensional terrain model of the wind power plant.
In this embodiment, the GIS system can acquire the three-dimensional terrain model of the wind farm to the technical staff arranges the fan sets on the three-dimensional terrain model.
In this embodiment, the GIS system acquires the three-dimensional terrain model of the wind farm, acquires and compiles high-precision images through the outgoing aerial survey of the unmanned aerial vehicle, then quickly establishes a three-dimensional geographic information environment, converts the three-dimensional geographic information environment into vectorized terrain data special for three-dimensional design, and guides the vectorized terrain data into the GIS system to generate the three-dimensional terrain model.
In addition, the mode of acquiring the three-dimensional terrain model by the GIS system also comprises the step of importing a three-dimensional terrain file made by three-dimensional terrain modeling software into the GIS system, the GIS system generates the three-dimensional terrain model of the wind power plant according to the three-dimensional terrain file, and the mode of acquiring the three-dimensional terrain model by the GIS system is not limited.
202. The geographical information system acquires layout site information of the fan and characteristic parameters of the fan.
After the GIS system generates a three-dimensional terrain model of the wind power plant, a technician can design a fan layout scheme of the wind power plant on the GIS system, and the GIS system acquires wind power plant design information input by the technician on the GIS system, wherein the wind power plant design information comprises layout site information of fans and characteristic parameters of the fans.
In this embodiment, the wind farm design information includes layout site information of the wind turbine and characteristic parameters of the wind turbine, where the layout site information of the wind turbine is information related to the layout site of the wind turbine, and specifically may include geographical information such as coordinates, longitude, latitude, and the like of the layout site of the wind turbine, and may also include information such as wind speed, wind frequency distribution, or geological structure of the layout site of the wind turbine; the characteristic parameters of the fan are parameters related to any characteristic attribute of the fan, and specifically may include technical parameters such as rated power, rated wind speed, blade number, cut-in wind speed, and the like of the fan, or information such as equipment cost, maintenance time, and the like of the fan.
In this embodiment, a technician may enter the characteristic parameters of the fan and the identity information of the fan in advance in the database of the GIS system, and associate the identity information of the fan with the characteristic parameters, where the identity information of the fan is any information capable of identifying the type or style of the fan, including but not limited to the type, brand, or manufacturer of the fan, so as to facilitate the technician to selectively arrange a certain fan through the identity information of the type, brand, or manufacturer of the fan when arranging the fan on the GIS system, and since the GIS system associates the identity information of the fan with the characteristic parameters in advance, the fan with a specific identity corresponds to a specific fan characteristic parameter, the GIS system may acquire the characteristic parameters of the fan from the database according to the identity information of the fan.
203. The geographical information system generates one or more alternative design solutions according to the layout site information of the wind turbine and the characteristic parameters of the wind turbine.
And after acquiring the layout site information of the fan and the characteristic parameters of the fan, the GIS system generates one or more alternative design schemes according to the layout site information and the characteristic parameters. The operation performed in this step is similar to the operation performed in step 103 in the embodiment shown in fig. 1, and is not described here again.
204. And the geographic information system generates evaluation information of the alternative design scheme according to the layout site information of the fan and/or the characteristic parameters of the fan.
After the GIS system generates the alternative design scheme, the evaluation information of the alternative design scheme can be calculated according to the layout site information of the fan of the alternative design scheme, the characteristic parameters of the fan and other information. In this embodiment, the evaluation information is a value of an index that can be used to evaluate the alternative design, and the value of the index may be a data type value.
For example, if the index for evaluating the alternative design is the power generation amount, the technician may set a formula for calculating the power generation amount on the GIS system in advance according to factors affecting the power generation amount, where the formula may include fan layout site information and/or characteristic parameters of the fan affecting the power generation amount of the wind farm, such as the wind speed of the layout site, the rated power of the fan, or the cut-in wind speed. Therefore, the GIS system can calculate and generate the generated energy information of the alternative design scheme according to the acquired layout site information and the characteristic parameters of the fan and a preset generated energy algorithm, namely the evaluation information of the alternative design scheme.
Similarly, if the index for evaluating the alternative design scheme is the number of hours of use, since the number of hours of use is closely related to the wind speed and the wind frequency distribution included in the layout site information of the wind turbine and the rated power, the maintenance time and other information included in the characteristic parameters of the wind turbine, a technician can preset an algorithm or a formula for calculating the number of hours of use on the GIS system according to the actual situation affecting the number of hours of use, and the algorithm includes the layout site information affecting the number of hours of use of the alternative design scheme and the characteristic parameters of the wind turbine. And the GIS system calculates the utilization hour number information of the alternative design scheme according to the calculation algorithm of the utilization hour number, namely the numerical value of the utilization hour number of the alternative design scheme.
It is understood that the evaluation information may be a value of the number of hours of utilization or a value of the amount of power generation, or may be a value of other index, and the skilled person may select other index for evaluating the alternative design in combination with the actual situation. For example, if a technician needs to evaluate an alternative design scheme by using the index of the effective wind hours, an algorithm of the effective wind hours can be preset on the GIS system, wherein the algorithm comprises characteristic parameters of the wind turbine such as cut-in wind speed, cut-out wind speed and hub height; if the civil engineering cost of the fan of the alternative design scheme needs to be evaluated, technicians can preset an algorithm for calculating the civil engineering cost of the fan on a GIS (geographic information system), wherein the algorithm comprises layout site information such as geological structures of fan layout sites. Therefore, the type of the specific index of the evaluation information is not limited as long as the evaluation information which can be used for evaluating the alternative design scheme and can be calculated by the GIS system according to the acquired layout site information and/or the characteristic parameters of the fan and the algorithm preset by the technical staff.
In this embodiment, the GIS system may calculate and generate the evaluation information according to one or more of the layout site information or the characteristic parameters, and the GIS system may calculate the evaluation information according to other types of wind farm design information, and since indexes of the evaluation information may be of various types, the type of the wind farm design information used for generating the evaluation information may be adjusted according to the index type and the calculation algorithm of the evaluation information. For example, if the GIS system needs to evaluate the candidate design solution by using the index of the average air density, the wind farm design information used for calculating the average air density should be the information of the average atmospheric pressure and the average air temperature of the wind farm, and is not limited to the wind farm design information such as the layout site information and the characteristic parameters. Therefore, the type of the wind power plant design information acquired by the GIS system is not limited, and under the condition that the evaluation information has multiple index types or calculation algorithms, the type of the wind power plant design information acquired by the GIS system can be adjusted along with the index types and the calculation algorithms of the evaluation information.
In the embodiment, the alternative design scheme is evaluated by using two evaluation indexes, namely the hours and the power generation amount, and the GIS system can calculate and generate evaluation information of the two indexes according to one or more items of layout site information or characteristic parameters so as to evaluate the alternative design scheme, so that the realizability of the scheme is improved.
In practical application, the design of the wind farm includes the design of the wind farm road and the design of the collecting line in addition to the process of fan layout, so that technicians may need to perform overall evaluation on the design of the wind farm by combining the design of the wind farm road and the collecting line. The following will describe in further detail a method for the GIS system to evaluate a wind farm design scheme including a wind farm road design or a collection line design.

301. the geographic information system obtains a three-dimensional terrain model of the wind power plant.

The operation of the GIS system to obtain the layout site information of the wind turbine and the characteristic parameters of the wind turbine is similar to the operation performed in step 202 in the foregoing embodiment shown in fig. 2, and details are not repeated here.
Technicians can also design wind farm roads on a GIS system, and the wind farm roads provide access and transportation roads for personnel and vehicles in the wind farm. Therefore, the wind farm design information acquired by the GIS system may further include road design information input by a technician on the system, where the road design information is information obtained after a wind farm road is designed on a three-dimensional terrain model, and includes, but is not limited to, information such as road length, manufacturing cost per kilometer, or building material usage.

And the GIS system generates an alternative design scheme according to the wind power plant design information acquired at one time. In this embodiment, a process from the beginning of the layout of the fan group and the design of the wind farm road to the end of the layout and the design by a technician is regarded as a primary design of the technician, and therefore, the GIS system correspondingly generates an alternative design scheme according to the layout site information, the characteristic parameters, and the road design information of the fans input by the primary design. When technicians lay out fans and design wind power plant roads for multiple times and input wind power plant design information for multiple times, the GIS system correspondingly generates multiple alternative design schemes, wherein the multiple alternative design schemes need to be designed by the technicians.
304. And the geographic information system generates evaluation information of the alternative design scheme according to the layout site information of the fan, the characteristic parameters of the fan and the road design information.
After the GIS system generates the alternative design scheme, the evaluation information of the alternative design scheme can be calculated according to the layout site information, the characteristic parameters, the road design information and other information of the fan of the alternative design scheme.
