Realization of monitoring the photovoltaic system based on configuration software

In order to improve the reliability and stability of photovoltaic system monitoring and decrease the workload, this paper sets up high-quality and highly efficient automatic data collection and analysis system by software configuration. The design of its functions, structure, interface, control strategy and system variables, protection, and so on are detailed. It use configuration software based on PC to exploit the operation interface in host computer, and adopt wide-plus intelligent instrument as the lower computer to data-acquisition. The host and lower computer are communicated by the field bus and RS-232. It monitors and controls photovoltaic system, acquires field data, deals with device faults in real-time.
