Research and application of collector line sizing in wind power field area

Abstract

Wind power generation has significant advantages such as huge reserves, energy and environmental protection, and thus is increasingly being emphasized by countries around the world, with rapid development momentum; in the design of wind farms, the selection of collector lines is not only a necessary guarantee for the safe and stable operation of wind farm lines, but also a powerful embodiment of the economics of project planning and construction; this paper presents a comprehensive analysis and detailed study of the selection basis of collector lines from the technical fields such as voltage level, laying form and so on of the collector lines of wind farms, combined with the necessary economic requirements of the project construction. This paper starts from the wind farm collector line voltage level, laying form and other technical fields, combined with the necessary economic requirements of engineering construction, the collector line selection basis for comprehensive analysis and detailed study, based on the economic factors affecting the collector line selection calculation basis, and the applicability of the selection results for demonstration. This study provides an in-depth discussion on the selection of collector lines for a certain plateau wind farm, and systematically evaluates the advantages and disadvantages of different collector line scenarios by means of a comprehensive technical and economic analysis. The results of the study show that in this particular scenario, the direct-buried cable scheme exhibits significant advantages in terms of comprehensive economic indicators. This finding emphasizes the key role of rational and optimized collector line design in the construction of wind farms, which not only helps to reduce the initial investment cost, but also improves the economic efficiency of wind farms in long-term operation. Through scientific selection and design optimization, wind farms can achieve power transmission more efficiently and economically, thus enhancing the competitiveness of renewable energy in the context of the current energy transition.
