Abstract:

According to the monitoring need of photovoltaic power station, this paper designed a set of monitoring system scheme for photovoltaic power station, and introduced the architecture of the scheme and the implementation of each function. The scheme's structure is divided into three layers from top to bottom: monitoring background, communication management unit and intelligent sub-station. the communication between monitoring background and intelligent sub-station is through communication manager, in which the real time operation data and state is sent to monitoring background, meanwhile, receives and executes the remote control command form monitoring background, thus can achieve the monitoring needs of entire photovoltaic power station. The practical use results show that this scheme can satisfy the requirement of real-time, stability and reliability of the system.

Key words: photovoltaic power generation, monitoring system, monitoring background, communication manager, intelligent sub-station
