In view of the current distributed photovoltaic grid-connected access system,which af-fects the overall operation efficiency of the system,the key technology of wireless communica-tion in the system is studied.Based on the actual requirements and attention,design communica-tion wireless private network;apply the anti-island device,calculate the total load impedance and impedance angle,provide the anti-island protection of the distributed photovoltaic grid-connect-ed access system;complete the topological adaptive island detection in the system operation to re-alize wireless communication.The examples prove that the application of new key wireless com-munication technologies can effectively improve the communication bandwidth and promote the overall operation efficiency of the system.
