Centralized Remedial Action Systems

Given the challenges of building new transmission lines, utilities must maximize the utilization of their existing assets without jeopardizing reliability. Implementing reliable and fast mitigation schemes can significantly reduce reserve margins while maintaining or even increasing reliability in some cases.

Traditional distributed remedial action schemes (RAS) that rely on complex device programming that interact in realtime across multiple substations can be challenging to develop, test, and maintain. It also increases cost and slows more widespread usage of wide-area RAS. Centralized RAS can lower the cost by providing a higher-level development environment with better simulation, testing, and management capabilities. This, in turn, enables more rapid and widespread implementation of RAS that can save utilities millions of dollars compared to other methods of RAS or adding capacity in existing transmission corridors.
