Integrated system architecture and technology roadmap toward WAMPAC

With the advancement of sensor, communication and information technologies, Wide Area Monitoring, Protection and Control (WAMPAC) systems have been identified as the new generation of solutions to improve power system planning, operation and protection. There are a number of Southern California Edison (SCE) advanced initiatives that are related to the WAMPAC systems. Despite differences among various WAM/WAC/WAP systems and capabilities, their similarities favor an integrated WAMPAC system architecture design. This paper reviews existing relevant smart grid initiatives at SCE and proposes an integrated WAMPAC system architecture designed to support SCE´s future smart grid and WAMPAC vision. It recommends a technology migration roadmap that considers technology maturity, practical deployment constraints, standardization, and a phased approach to ensure an effective and feasible WAMPAC system under the overall smart grid framework.
