A data exchange method of WAMS based on IEC61970

With large-scale implementation of smart grid, wide area measurement system (WAMS) based on PMU will become the basic platform to provide the online power system analysis, real-time monitoring and control. According to the extended CIM guidelines, a WAMS data model was established in this paper to realize data exchange and sharing between WAMS system and other systems. Combined with IEC 61970-404-speed data (HSDA) standard, a scheme of WAMS data exchange including data exchange framework, overall design of data exchange and data subscriptions was described in the paper. This scheme integrates WAMS system with other systems more effectively and makes other applications access WAMS data more easily.
