In order to meet the needs of emergency communication for major emergency disaster rescue, a wireless emergency communication relay system based on tethered UAV platform is studied. From the perspective of practical application, the characteristics and network coverage of the emergency communication system are analyzed. The mooring UAV platform is equipped with various communication loads such as MESH(wireless grid network communication), 4G-LTE( Long term evolution fourth generation mobile communication) base station, AIS (Automatic Identification System) and so on, which are kept on the communication support ship. When the communication support ship enters the scene of maritime emergencies, the tethered UAV platform lifts off ,stays for a long time and realizes the relay communication service of various carriers within a radius of tens of kilometers through its various communication payloads, which provides key communication support for the Marine emergency communication network. The actual field test of the prototype system shows that the data transmission is stable and reliable, and the short message transmission is normal, which can meet the emergency communication demand of disaster rescue.

Secured Communication

In an electrical distribution network, Logic Selectivity significantly reduces both the number and duration of outages. Generic Object-Oriented Substation Events (GOOSE) have a key role in the decision-making process of substation protection devices using GOOSE-based Logic Selectivity. GOOSE messages are exchanged between remote protection devices over the communication network. Secured communication with low latency and high reliability is therefore required in order to ensure reliable operation as well as meeting real-time requirement of the Logic Selectivity application. There is thus a need to evaluate feasibility of the selected communication network technology for Logic Selectivity use cases. This paper analyzes reliability of cellular 4G/LTE Internet for GOOSE communication in a Logic Selectivity application. For this purpose, experimental lab set-ups are introduced for different configurations: ordinary GOOSE communication, secured GOOSE communication by IPsec in Transport mode, and redundant GOOSE communication using the IEC 62439-3 Parallel Redundancy Protocol. In each configuration, the GOOSE retransmissions are recorded for a period of three days and the average GOOSE transmission time is measured. Furthermore, the measured data is classified into histograms and a probability value for communication reliability, based on the transmission time, is calculated. The statistical analysis shows that 4G Internet satisfies the real-time and reliability requirements for secure and highly available GOOSE-based Logic Selectivity.
