A Technical Scheme of Microgrid System with Micro Turbines

This paper researches microgrid technology scheme with micro turbines.First,the cold and electric supply systems are introduced.Then,the technical issues of micro turbine grouping,grid structure,operation mode,protection coordination and settings are researched.The alternative technical schemes are analyzed and compared with respect to their technical advancement,feasibility,economics and reliability,and the final scheme is put forward.Finally,some advices about system protection configuration and settings are given,and the operating mode of the recommendatory scheme is introduced in detail.The research results show that the recommended design scheme can meet the requirements of the microgrid and is easy to be implemented.By the proposed scheme,power supply reliability of the whole system can be improved.
