Abstract
With the rapid development of the photovoltaic industry in recent years,the supervisory and control system in the photovoltaic power station is getting more and more attention. In view of its characteristics of numerous photovoltaic equipments,scattered distribution and use of serial communication,a centralized communication scheme based on virtual serial port is proposed.To save investment and improve maintenance efficiency,the serial server is used to establish the virtual serial port on the Ethernet.The centralized front directly communicates with the devices cancelling the distributed fronts.A mapping method of virtual serial port is put forward,with the communication efficiency and network load analyzed in the case of coexistence of a large number of virtual serial ports.The feasibility of the scheme is finally verified through a designed prototype in a 20 MW photovoltaic power station.关键词
