On Design of Hydropower System Aided by Internet of Things Architecture with OPC-UA and MQTT

The application of Internet of Things (IoT) technology in hydropower is of great significance to further improve the automation level of hydropower network. In this paper, IoT is used to aided hydropower system to promote the standardization of hydropower network communication and realize the efficient transmission of data models. First, we design an architecture of the hydropower aided by loT, which can implement the messages exchanges among the cloud, the edge and the end. Second, we design the communication methods with Message Queuing Telemetry Transport (MQTT) and OPC unified Architecture (OPC-VA), where the cloud and edge communicate with MQTT and the edge and the end communicate with OPC-VA, Third, we build an experimental environment platform, Plug and play is taken as an example to verify the effectiveness. Experimental results reveal that the information interaction method of hydropower aided IoT based on MQTT and OPC-VA, can effectively improve real-time performance and reliable for message exchange.
