基于深度学习模型识别风电场避让物的方法研究

RESEARCH ON METHOD OF IDENTIFYING WIND FARM AVOIDANCE OBJECTS BASED ON DEEP LEARNING MODELS

  • 摘要: 近年来,由于在新建风电场和需要进行技改的老旧风电场周边往往已建有风电场,因此风电场在新建或技改时除了需要避让生态保护红线、永久基本农田、自然保护区、风景名胜区等国家限建区域,以及需要考虑风电场内风电机组之间的尾流影响外,还需要重点关注周边风电场对新建或需要技改的老旧风电场的尾流影响。当针对尾流影响进行计算时,工程师采用当地遥感影像对周边已建风电场的风电机组逐个进行人工标记,但该方法容易造成风电机组机位统计缺漏,过失误差较大。提出一种基于深度学习模型识别风电场避让物的方法,利用深度学习模型对遥感影像中已建风电场的风电机组、民房等敏感因素进行识别标记,采用OpenWind软件对这些敏感因素进行避让,并快速进行风电机组布置。研究结果表明:利用计算机分析并标记避让物的结果准确、不易产生遗漏,可有效消除过失误差;同时,大幅降低了标记避让物的工作量,有效减少了大量的繁杂、低效、高重复性的工作,大幅提高了识别避让物的工作效率和结果精度。

     

    Abstract: In recent years,due to the fact that wind farms are often built around newly built wind farms and old wind farms that require technological upgrades,wind farms not only need to avoid national restricted construction areas such as ecological protection red lines,permanent basic farmland,nature reserves,scenic spots,etc.,meanwhile need to consider the wake effects between wind turbines on site,but also need to focus on the wake impact of surrounding wind farms on newly built or technological upgrade wind farms.When calculating the impact of wake flow,engineers using local remote sensing images to manually mark the surrounding wind turbines of the existing wind farms one by one can easily result in missing statistics of wind turbine positions and significant gross error. This paper proposes a method for identifying wind farm avoidance objects based on deep learning models. The deep learning model is used to identify and label sensitive factors such as built wind turbines in the wind farms and residential buildings in remote sensing images. OpenWind software is used to avoid these sensitive factors while quickly arranging wind turbines. The research results show that the use of computers to analyze and label avoidance objects is accurate,less prone to omissions,and can effectively eliminate errors caused by negligence. At the same time,it significantly reduces the workload of lable avoidance objects,effectively reducing a lot of complex,inefficient,and highly repetitive work,and greatly improving the working efficiency and accuracy of identifying avoidance objects.
