零能耗小屋的光储微网与智能控制系统设计

Design of photovoltaic/battery micro-grid and intelligent control system of zero energy consumption house

结合光伏并网发电与节能控制的优势,设计了一种基于可编程逻辑控制器(PLC)的光储微网和智能控制系统。采用分布式结构,通过工业以太网实现了下位机PLC与上位机触摸屏和Groov服务器的通信及远程发布的功能,完成了基于网络的实时远程监控。通过智能控制,实现了在维持室内恒温和光照温和与空气优良的前提下,降低系统的能耗,并且实现了光伏并网发电量与系统耗电量的平衡。

Combining advantages of photovoltaic（ PV） grid-generation and energy-saving control,an intelligent control system is completed,which is based on programmable logic controller（ PLC）. A distributed structure is used,industrial Ethernet is used to achieve the communication of PLC of lower PC and touch screen of upper PC and Groov server and remote publishing,real time remote monitor based on network is achieved. By intelligent control,energy consumption of this system is reduced and the objective that there are an appropriate illumination and air quality and constant temperature in the house is accomplished,and balance between grid-generation capacity of PV system and power consumption of system.
