Ensuring Uptime of WAMS Network with the Help of Common IT Tools - Case Studies

摘要

India started implementing Synchrophasor technology or Wide Area Monitoring System (WAMS) with the installation of four PMUs and one PDC in Northern Region in year 2010. Gradually more projects were implemented and finally all were integrated to a central PDC creating a Nationwide WAMS network. Since than, the WAMS, in India, is helping grid operators in monitoring the pulse of Indian grid at national as well as all regional control centres. Data and visualization from WAMS have now become an essential tool for real-time grid operation for Power System Operation Corporation in India. Hence, round the clock availability of WAMS network is highly critical for the control room operators. Since, the WAMS projects were implemented on the pilot basis, the redundancies of components were not envisaged in the projects. This posed the big challenge in maintaining high availability of the network. Furthermore, non-availability of WAMS specific diagnosing tools posed further challenge in diagnosing and trouble shooting the WAMS network. Power System Operation Corporation utilised commonly available IT network tools and could ensured maintaining the availability of the WAMS network in India. This paper presents real-life case studies of various WAMS network related issues faced during last many years of its operation and how these could be resolved with the help of Wireshark and PRTG Network Monitor and other IT tools.
