集中式光伏电站中压电缆敷设交叉施工的影响因素及施工部署研究OA

In order to ensure the smooth implementation of cross construction of medium voltage cable laying in large centralized PV power stations,this paper first analyzes the problems existing in such cross construction of cable laying.Secondly,the key influencing factors in cross construction are identified and the hierarchical topological relationships between each influencing factor are sorted out through the DEMATEL-ISM method.Finally,a circle interference model is proposed to guide the deployment of cable laying cross construction,and a detailed construction schedule and theoretical resource allocation are provided using a centralized PV power station as an example.The research results show that:1)The number of construction personnel is an essential element of cable laying cross construction,and personnel allocation needs to be highly valued in construction deployment.According to DEMATEL's calculation results,the centrality values of the three influencing factors located in the first quadrant,namely cable laying length,construction mechanical quantity,and safety management,are relatively high,indicating that they have the greatest impact on the cable laying cross construction system.2)For a centralized PV power station,a circle interference model is adopted to effectively guide the overall deployment of cable laying cross construction for 28 circuits of the booster station section in the western area of the PV power station The starting positions and operation sequences of each operation team are determined.The deployment of construction resources is reasonable and can meet the on-site construction schedule,ensuring the construction period.
