Abstract:The construction of smart power plant has gradually become the goal and trend of the new era. Based on the current development of smart power plant,the three layer architecture of smart power plant,that is,ntelligent perception,intelligent control and smart management and control,is programmed and interpreted. A method of two - dimensional and three - dimensional linkage monitoring for smart plant is proposed. Besides that,according to national development strategy of " Internet plus" for wisdom energy,coordinated supply and cascade utilization of multi - energy flow are the key points. The architecture of multi - energy flow management and control system is studied,which is firstly applied and implemented in engineering project. The characteristics of engineering design are analyzed and summarized,and the possessed functions are described.
