Title Research of photovoltaic power station monitoring system based on fiber ring network
Abstract
Solar photovoltaic power generation is making full use of solar energy, which is one of the most convenient ways. In recent years, it has received a widespread attention in the world. The existing photovoltaic power stations are mostly in the remote areas, which will take a lot of manpower and material resources to manage. Therefore, it is very significant for the photovoltaic power station to adopt centralized monitoring and management. Concerning a PV power generation project, a whole technology scheme of the Photovoltaic grid-monitoring system is proposed in this paper.
Firstly, the research status of photovoltaic power station monitoring technology, solar photovoltaic (PV) grid power generation principle and the classification are introduced. Secondly, the monitoring system adopts the self-healing type optical fiber ring Ethernet as the backbone network of the communication system. And we analyze the characteristics of the network structure of self-healing type optical fiber ring Ethernet. Finally,we also analyzed the function structure of monitoring system. The station communication is fulfilled with Modbus communication protocol, and the database of the monitoring system is also set up.
By testing the data processing, the monitoring system designed in this paper can run reliably and steadily, and meets the requirement of photovoltaic power station.
Keywords：Photovoltaic power generation, self-healing type, fiber ring network, monitoring system
