Wind Farm Road Optimization Design Method Based on Multiple Linear Programming Model

在风电场道路自动选线设计中,为了满足相关技术规范,确保车辆行驶安全,减少施工工程量,本文提出一种基于多元线性规划(LP)模型的道路优化设计方法,实现了在三维GIS环境下顾及风电工程建设成本及道路线形设计规范的平面道路快速构建。以辽宁省杨树湾及陕西省定边两个风电场道路设计为例,结果表明该方法在选线基础上平均道路总长降低22%,平均道路挖填方量降低19%,最终获得建设成本最优及规范化修正的线路设计方案。实验表明该方法明显提升了道路设计自动化水平与能力,为道路要素自动提取和批量标准化出图奠定了基础,具有良好的实用性和有效性。

In the automatic route selection of wind power roads,in order to meet the relevant technical specifications,guarantee the safety of the vehicle and reduce the amount of engineering,this paper proposes a road optimization design method based on multivariate linear programming model.This method realizes the rapid construction of flat roads considering wind power engineering construction cost and road line design specification in 3D GIS environment.Taking the road design of two wind farms in Yangshuwan in Liaoning Province and Ding bian of Shanxi Province as an example,the results show that the average road length of the method is reduced by 22%on the basis of roads selection,and the average road excavation volume is reduced by 19%,and finally the construction cost is optimized.The experiments show that this method significantly improves the road design automation level,and lays a foundation for automatic extraction of road elements and batch standardization,and has good practicability and effectiveness.
