Framework and applications of WAMS light communication system

The dynamic response of distribution network is becoming more and more complicated, as the rapid development of renewable energy. Wide Area Measurement System light (WAMS Light) can monitor the distribution network synchronously. The communication of real-time and high-speed data has been put on the research agenda. Firstly, analyzes the existing communication network of distribution network, and proposes to use Long Term Evolution (LTE, 4G) for WAMS Light. Secondly, discusses the IEC 60870-5-101 and the IEEE C37.118.2 protocol, and puts forward suggestions for the WAMS Light protocol. Thirdly, studies the communication security, and suggests using DES and RSA algorithm based on Key Distribution Center (KDC) in WAMS Light. Finally, the main station has received the PMU Light data smoothly through a platform containing PMUs Light and simulated PMUs Light. This means 4G, WAMS Light communication protocol, DES and RSA based KDC can be used in the communication of WAMS Light.
