[0029] In this embodiment, a wind energy resource evaluation method used for the above-mentioned mobile terminals such as mobile phones and tablets is provided. FIG. 3 is a flowchart of the wind energy resource evaluation method according to the embodiment of the present application. As shown in FIG. 3, the flow includes the following steps.
[0030] Step S301: Obtain wind energy resource data, perform qualitative index evaluation on the wind energy resource data, and generate a qualitative index confidence. Here, the qualitative index includes a reliability index of the wind energy resource evaluation result and a stability index of the wind energy resource.
[0031] Specifically, the above step S301 includes the following steps.
[0032] Step S3011: Perform a reliability judgment on the wind energy resource evaluation result in the wind energy resource data according to the resource measurement parameter, and generate a reliability index value of the wind energy resource evaluation result.
[0033] Specifically, the resource measurement parameters include the observation location (coordinates), on-site photos, elevation, wind measurement time zone, surrounding terrain, the composition of the wind measurement equipment and the wind measurement height, maintenance records, mesoscale data, operation data of projects constructed in the vicinity, the completeness rate of the observation data, the processing methods for unreasonable data and missing data, the wind speed and wind power before and after data interpolation, the wind direction frequency, the wind shear index, the wind speed estimation method and results at the hub height, and the measurement data comparison chart (wind speed, wind direction, turbulence, etc.) by different sensors at the same height.
[0034] Step S3012: Based on the long-sequence resource characteristic data, monthly resource data, and quarterly resource data, perform a stability judgment on the wind power resource data in the wind energy resource data, and generate the stability index value of the wind power resource.
[0035] Specifically, the long-sequence resource characteristic data and monthly resource data include the meteorological element characteristics, resource characteristics, annual and intra-year change laws of wind speed, meteorological element characteristic values, statistics of low temperatures in winter, the number of icing days in high-humidity regions, and the actual operation stop status of surrounding wind power plants, the correlation between the wind speed per hour at the meteorological observation station and the measurement tower in the same time zone, the annual change of the long-sequence wind speed at the measurement tower in the same time zone, the consistency with the wind direction frequency distribution law, and the observation data of the long-sequence wind speed.

[0037] Specifically, the confidence level is given based on the qualitative index. Here, the resource stability mainly performs a stability judgment based on the long-sequence resource characteristic data, monthly and quarterly resource data. The reliability of the evaluation result is mainly judged by the data quality, algorithm, key parameters, etc. used in the resource measurement process. The reliability parameter is given by summarizing the resource stability and the reliability of the evaluation conclusion.
[0038] The method for evaluating wind energy resources according to the present application realizes the feasibility evaluation of wind energy resources by performing qualitative index evaluation on wind energy resource data, and provides a basis for project decision-making.
[0039] Step S302: Perform quantitative index evaluation on the wind energy resource data to generate a quantitative index score. Here, the quantitative indexes include hub height average wind speed index, average wind power density index, effective wind hour number index, wind shear index, turbulence intensity index, and wind power density level index. For details, refer to step S102 of the embodiment shown in FIG. 1, and the description here is omitted.
[0040] Step S303: Obtain the quantitative index weights, and determine the total score of the wind energy resources based on the qualitative index confidence, quantitative index score, and quantitative index weights. For details, refer to step S103 of the embodiment shown in FIG. 1, and the description here is omitted.
[0041] In this embodiment, a method for evaluating wind energy resources used in the above-mentioned mobile terminals such as mobile phones and tablets is provided. FIG. 4 is a flowchart of the method for evaluating wind energy resources according to an embodiment of the present application. As shown in FIG. 4, the flow includes the following steps.
[0042] Step S401: Obtain wind energy resource data, perform qualitative index evaluation on the wind energy resource data, and generate a qualitative index confidence. Here, the qualitative indexes include a reliability index of the wind energy resource evaluation result and a stability index of the wind energy resource. For details, refer to step S301 of the embodiment shown in FIG. 3, and the description here is omitted.
[0043] Step S402: Perform quantitative index evaluation on the wind energy resource data to generate a quantitative index score.
[0044] Specifically, step S402 includes the following steps.
[0045] Step S4021: Determine the hub height average wind speed index value based on the wind speed observation sequence in the wind energy resource data and the number of wind speed sequences within the target time period.
[0046] Specifically, the calculation formula for the hub height average wind speed index value is shown in JPEG2025524269000005.jpg16124, where E represents the hub height average wind speed index value, V i represents the wind speed observation sequence, and n represents the number of wind speed sequences within the average wind speed calculation time period (year, month) (i.e., the number of wind speed sequences within the target time period).
[0047] Step S4022: Determine the average wind power density index value based on the monthly average air density, wind speed sequence in the wind energy resource data, and the number of wind speed sequences within the target time period.
[0048] JPEG2025524269000006.jpg57170
[0049] Step S4023: Determine the effective wind power hours index value based on the effective hours of the wind speed of the blower within the target time period in the wind energy resource data.
[0050] Specifically, count the number of hours of the wind speed of the blower within the target time period that is higher than the cut-in wind speed and lower than the cut-out wind speed, and then determine the effective hours.
[0051] Step S4024: Determine the wind shear index value based on the current wind speed and the height of the wind speed in the wind energy resource data.
[0052] Specifically, the wind shear index indicates how much the wind speed changes with height. A large value indicates that the wind energy increases rapidly with height and the wind speed gradient is large, while a small value indicates that the wind energy increases slowly with height and the wind speed gradient is small.
[0053] JPEG2025524269000007.jpg45170
[0054] Step S4025: Determine the turbulence intensity index value based on the pulsating wind speed value and the average wind speed value in the wind energy resource data.
[0055] JPEG2025524269000008.jpg45170
[0056] Step S4026: Compare each of the annual effective wind power density, the annual cumulative number of hours of wind speed, and the annual average wind speed in the wind energy resource data with a preset threshold value to determine the wind power density level index value.
[0057] Specifically, when the annual effective wind power density is greater than 200 W / m 3 (watts per cubic meter), the annual cumulative number of hours of wind speed of 3 to 20 m / s (meters per second) is greater than 5000 h (hours), and the annual average wind speed is greater than 6 m / s, the current wind power generation area in the wind energy resource is an area rich in wind energy resources, and the wind power density level index value is 4.
[0058] Optionally, when the annual effective wind power density is 200 - 150 W / m 3 and the annual cumulative number of hours of wind speed of 3 to 20 m / s is 5000 h - 4000 h, and the annual average wind speed is about 5.5 m / s, the current wind power generation area in the wind energy resource is a second-class area rich in wind energy resources, and the wind power density level index value is 3.
[0059] As an option, the annual effective wind power density is 150 - 100 W / m 3 and the annual cumulative number of hours with wind speeds of 3 - 20 m / s is 4000 h - 2000 h. When the annual average wind speed is about 5 m / s, the current wind power generation areas in wind energy resources are areas where wind energy resources are available, and the wind power density level index numerical value is 2.
[0060] As an option, the annual effective wind power density is less than 100 W / m 3 and the annual cumulative number of hours with wind speeds of 3 - 20 m / s is less than 2000 h. When the annual average wind speed is 4.5 m / s, the current wind power generation areas in wind energy resources are areas with poor wind energy resources, and the wind power density level index numerical value is 1.
[0061] Step S4027: Match each of the hub height average wind speed index numerical value, average wind power density index numerical value, effective wind hour index numerical value, wind shear index numerical value, turbulence intensity index numerical value, and wind power density level index numerical value with the scoring rule database to generate a quantitative index score including the hub height average wind speed index score, average wind power density index score, effective wind hour index score, wind shear index score, turbulence intensity index score, and wind power density level index score.
[0062] Specifically, based on the above - mentioned each quantitative index numerical value, quantitative scoring is performed on a scale of 0 - 10 to obtain a quantitative index score.
[0063] The wind energy resource evaluation method according to the present application realizes a rationality evaluation of wind energy resources by performing a quantitative index evaluation on wind energy resource data, and provides a basis for project decision - making.
[0064] Step S403: Obtain the quantitative index weights, and determine the total score of the wind energy resources based on the qualitative index confidence, the quantitative index scores, and the quantitative index weights. For details, refer to Step S303 of the embodiment shown in FIG. 3, and the description here is omitted.
[0065] The following describes the process of the wind energy resource evaluation method through a specific embodiment.
[0066] Embodiment 1: The full life cycle evaluation process of a wind power project mainly includes the evaluation of the project's pre-approval documents, the feasibility study report evaluation, the preliminary design report evaluation, the EPC tender purchase evaluation, the equipment quality evaluation, and the operation evaluation of the project after production starts.

[0073] (2) Qualitative indicators: Confidence levels are assigned based on qualitative indicators. Here, for resource stability, stability judgments are mainly made based on long-sequence resource characteristic data, monthly and quarterly resource data. The reliability of the evaluation results is mainly determined by the data quality, algorithms, key parameters, etc. used in the resource measurement process. By summarizing the resource stability and the reliability of the evaluation conclusions, reliability parameters are given. According to the influence of the indicators of each part on the overall investment return of the project's overall decision-making, weight ratios are set. (Confidence level * Σ(score * weight)) is the final score result corresponding to the evaluation content of this part.
[0074] The sum of the weights of each part is 100%, and the total score is on a scale of 0 to 10. The default total score of the system is that 60 points (inclusive) or less is "poor", indicating that the evaluation of this part fails; 60 to 85 points (inclusive) is "good", indicating that the evaluation of this part conditionally passes after modification and optimization; 85 points or more is "excellent", indicating that this part passes the evaluation.
