Research on Optimization Method of Mixed-Voltage Tree-shaped Collector Line for Onshore Wind Farms
摘要
Abstract
The optimization of the collector system is an important issue that needs to be addressed after the layout and site selection of wind turbines within a wind farm.Collector systems typically adopt structures such as chain,ring,tree or hybrid configurations,and their topological optimization is classified as an NP-hard problem.This paper takes the design of the collector line of a wind farm in Fuyang,Anhui Province as an example to carry out the research on the optimization method of the collector line of onshore wind farms.Firstly,based on the layout position of the wind turbine units and the installation requirements of electrical equipment,a Gaussian mixture model is adopted to cluster the wind turbine units and determine the collector lines connected to each wind turbine unit.Secondly,with various factors taken into account,such as the cable cost and power loss of the collector line with a tree topology structure,a cost function of the collector line is established;combined with the line topology structure,terrain environment and local policy requirements,an optimization model of the collector line is developed,which provides a model basis for generating the most economical collector line scheme.Then,the minimum spanning tree algorithm for solving the optimization model of the collector line is designed to obtain the optimal or near-optimal tree-shaped collector line schemes respectively.Finally,according to the requirements of the 35 kV and 66 kV voltage levels of the Fuyang Wind Farm,different-structured collector line schemes are generated.Through comparative analysis are illustrated the application prospects of the 66 kV collector line scheme in onshore wind farms.关键词
