Real-time synchronous data visualization for wide area power systems

With the construction of global energy interconnection, plenty of fluctuating renewable energy access the distribution network, power system dynamic behavior is more complex. The wide-area measurement system light (WAMS Light) records the actual variation of the grid in the distribution network with high accuracy. Exploring the value of high-density, large-scale synchronous data and comprehensive visualization can efficiently reflect the behavior of the system. An open and interactive WAMS Light data visualization platform (WAMSLVP) is built with three-tier structure. WAMSLVP is designed by analysing the function requirements in multi-information fusion, multi-angle analysis, multi-layer integration, program flexible access based on the characteristics of distribution network. And WAMSLVP integrates the frequency, voltage magnitude, angle phase and other power information with the non-power information as multiple layers to compositive display based on geographic information system (GIS), facilitating the dispatchers simultaneously capture multiple information from different analysis just by a glance.
