Design Of Distributed Generation For Intelligent Green Building

While construction shelters human beings from the rain and wind, it’s also the colony of a great consumption of energy resources. Starting from Distributed Generator applied in the intelligent green building, this thesis devises a effective solution for the Distributed Generator application into the building by utilizing the Distributed Generator for the building combined with Micro-grid technology on the basis of intelligent supply of power for the intelligent building, and proposes the concept of Micro-grid in Building in which there is a working mode that controls a kind of Distributed Generator to cooperate each other.The thesis first introduces features of the intelligent building, green building. Then we introduces functions and features of photovoltaic power generation, wind power generation, fuel cell generation, storage battery and micro gas turbine power generation. And the introduction of those paves the way for the design of the Distributed Generator applied in the intelligent green building.The article makes a choice on the kinds of the suitable Distributed Generator in building. Attention is concentrated on the use of Photovoltaic power generation. Based on the Building Integrated Photovoltaics (BIPV), kinds of the Distributed generations in building are designed, which provide buildings with green power energy; Through the analysis of intelligent building systems, distributed power generation systems are integrated in Building Automation System (BAS), which realizes monitoring and controlling on the kinds of Distributed Generator in building.Finally, we propose and design a control system of Micro-grid in Building based on Programmable Logic Controller. We apply network communication system in intelligent building to form the basic framework of control system of Micro-grid in Building. Then the study works on introducing the hardware design of the control system, containing the selection of the hardware, the identification of the PLC hardware connection between upper and lower system and the identification for the protocol of the network communication system in each layer. Finally, we do further on the function of the control system of Micro-grid in Building, which includes designing on the procedure flow chart of the upper control system, on the procedure flow chart of photovoltaic energy generation system, and on the procedure flow chart of fault spare miniature gas turbine power generation batch startup program.In short, we devise Distributed Generator applied in the intelligent green building to realize the coordination patterns in different environment by the technology of Micro-grid. It improves the utilization of renewable energy and attempts to save energy resources, besides protecting our environment.
