| Distributed power generation can effectively relieve the increasing environmental pressure.In the current situation of increasing environmental protection demand,it is necessary that the power generation industry must not only improve power generation efficiency,but also reduce its costs.Compared with traditional power generation methods,distributed power generation,which uses renewable and clean energy such as wind energy and solar energy to generate electricity,has the advantages of less pollution and less noise and has a significant improvement effect on air quality.The construction of 50MW distributed photovoltaic power generation system,mainly making use of solar energy resources,can effectively realize the optimization of energy structure and reduce coal consumption,which has an effective role in promoting sustainable economic development.At the same time,the construction of distributed power generation systems can also play a role in peak and valley filling in the operation of power grid systems,further enrich the power supply methods,and actively carry out distributed photovoltaic power stations and access to power generation research is of great significance.A construction plan for a 50MW distributed photovoltaic power generation system is proposed in this paper,which mainly focuses on three issues:analysis on the working principle of photovoltaic cells,a grid-connected model of photovoltaic power plants,a 50MW photovoltaic power generation access grid construction plan for the current distributed photovoltaic power generation grid access method,and related equipment selection methods.It is also concluded the analysis on the impact of distributed photovoltaic power generation grid access on the distribution network,including the impact on the distribution network power flow,the distribution network loss,the distribution network voltage,and discussion on the needs of relay protection configuration.The Jiaxian photovoltaic power generation project is taken as the engineering background,and the overall scheme of the photovoltaic system is designed,concluding its power generation and the secondary design of its access system.Finally,combined with the market status and manufacturer’s information,the 25-year economic benefit estimation analysis on the distributed photovoltaic power station is put into operation,and the influencing factors are discussed.50MW photovoltaic power generation access grid solution is proposed here The construction of the power station conforms to the national and local industrial policies and the sustainable development goals.The installed equivalent of the photovoltaic power station for many years is 1753 hours,which has a huge effect on reducing environmental pollution and protecting the ecological environment. |
