Design And Implementation Of The Photovoltaic And Energy-Saving Monitoring Systems For A Zero Energy House

With the rapid expansion of building scale and the increased comfort requirements for residential buildings, energy consumption issues become increasingly prominent. New energy acquisition and intelligent energy saving control are effective technological applications to reduce building energy consumption. The thesis demonstrates the zero-energy consumption of Sunny Inside in Solar Decathlon China2013. As a technical team leader of Xiamen University, the author designed the photovoltaic system, energy monitoring system, intelligent control system and distribution system of Sunny Inside. The practical operating data and performance of the systems mentioned above are discussed.The main research works are as follows:Photovoltaic system:Photovoltaic system was designed by photovoltaic division and architecture division with the meteorological data from Datong city, Shanxi province and the help of simulation software for the energy balance analysis.Energy monitoring system:Use CC-Link fieldbus network and Ethernet combining with real-time energy monitoring equipment from device layer, PLC and energy saving server from control layer, remote PC and mobile terminal from information layer as an energy monitoring system. And design the hardware, software and communication for this system.Intelligent control system:Combining the energy monitoring system and intelligent control system by a Q PLC, and build a communications network that compatible with standard Modbus protocol, no protocol and Ethernet protocol; An energy saving solution to control central air conditioning and active phase change material system was advanced; Hardware, software, communication and man-machine interface for this system were designed.The performance curves of photovoltaic power generation system, the performance curves of energy-saving monitoring system and the energy balance statistics are given on the basis of the operating data of the Sunny Inside during competition. We will do more zero energy house energy saving research based on this platform in the future.
