A Study Of Fishery Photovoltaic Hybrid Supply System In An Area Of Zhejiang

Nowadays,the photovoltaic generation increases in the proportion of power generation way with the advantages of highly efficient,cleanness and sustainable.With the mature of technology,the outlook of photovoltaic can be one of the issues of the power generation technology.With the speeding up of the power grid development,photovoltaic power generation also tends to be intelligent,automation.Under the support of policy and technology over the recent years,the photovoltaic industry in Zhejiang province develops rapidly and the interconnection capacity increases every year.At the same time,Zhejiang has developed water system and many ponds,so the fisheries development leads in the country.But simple fishery production mode can't satisfy the needs of modern fishery development.The farmers' income and light energy utilization rate is low only relying on fisheries development.Therefore,some scholars put forward to combine the advantages of both photovoltaic and fishery and dress lessons from the agriculture light complementary power generation engineering plan.Then,a new power generation mode namely fishing light complementary is suggested.This power mode doesn't occupy additional land resources,and combines fishery production and power generation cleverly.This mode not only satisfies the need of aquaculture,but also realizes the photoe lectric conversion,which created a new fishery production and operation mode.Through the construction of fishing light complementary project,an integrated and demonstrated project with rainwater,water-saving system,aquaculture,photovoltaic power generation is built,which will become a demonstrated area residents using new energy,green and circular economy.It will accelerate the construction of new countryside and carry on the beneficial exploration and practice.This article uses somewhere in Zhejiang province,and discusses the design of fishery-PV hybrid supply system.First of all,the region geology,hydrology,power system,air condition of the location of the fishery-PV hybrid supply system is analyzed.And the feasibility of the project is accounted for.The solar energy resources here is adequate,and the engineering geological conditions is stable,which means this place has enough condition to develop this project.Secondly,this paper designs the photovoltaic power plant,including photovoltaic system,the first side of system,the second side of system,and secondary wiring design.Then this paper describes this system from the choice of photovoltaic system components,the access to system design,short-circuit current,reactive power calculation,lighting protection design and the selection of relay protection device.Thirdly,this paper designs the project of fishery-PV system,including the first side and equipment list etc.,of electrical design,the selection of circuit conductor,gro und wire and cable etc.,and the communication scheme,the set of equipment and communication materials of communication engineering.Finally,this paper summarizes the content discussed in this article,and puts forward problems remained to be studied further in depth.
