Abstract：This paper introduces a new type of PEDF LED lighting system of Shanxi·Xiaohe New Town International Convention and Exhibition Center project in Shanxi Province. The system adopts radial topology

single‑pole connection mode,and has two voltage levels:DC 750 V and DC 220 V. In terms of system protection configuration,a series of new DC protection devices such as centralized protection and active monitoring & protection devices have been developed. In terms of capacity design,the photovoltaic system should be installed as enough as possible,and the energy storage capacity should be determined based on the load power and support time. At the same time,

the project has developed a system monitoring and management system,which provides system scheduling functions while monitoring the system’s operating status in real time. The operation results show that the project has high economic and social benefits.
