Beschreibung:
Low-voltage distribution networks lack monitoring, have a large maintenance workload, and have poor interoperability. Based on IEC 61850, the standardization of the information model and the information exchange method of Intelligent Electronic Devices (IED) are realized. Subsequently, the interconnection, interoperability, and plug-and-play of devices are realized. The article analyzes the communication scenarios between the power distribution Internet of Things (IoT) cloud master and the edge devices. It investigates the communication service requirements and the Abstract Communication Service Interface (ASCI) mapping implementation method of IEC 61850 based on Message Queue Telemetry Transport (MQTT) communication protocol. A testing platform is built, and the feasibility of the mapping method is verified by functional and performance experiments
