Abstract
To achieve the carbon peaking and carbon neutrality goals,China is accelerating the development of renewable energy power generation projects.As a critical form of renewable energy infrastructure,the cost optimization of photovoltaic(PV power station construction has become a key industry focus.This study takes the 90 MW mountain photovoltaic power station in Xiangzhou County,Laibin City,Guangxi,as a case study.Using Caiyun Design Software,the differences in cable costs under four distinct layout schemes for inverters and box-type step-up transformers are analyzed.The results indicate that:1 The comprehensive cost of 35 kV medium-voltage cables accounts for only 20%to 30%of total integrated expenses,exerting minimal impact on overall costs,whereas DC cables and low-voltage AC cables emerge as the primary cost drivers;2 Optimizing equipment layouts,particularly the scheme with centralized box-type transformers and inverters positioned nearby,significantly reduces cable investment costs;3 Prioritizing inverter proximity to box-type transformers is recommended under terrain constraints.This research provides scientific references for feasibility assessments and preliminary designs of similar mountain PV projects,offering practical guidance for the industry.关键词
