Syncro-phasor based voltage and var management

The growing complexity of interconnected electric grids is creating operational challenges for electric utilities and the nation's infrastructure as a whole. Events in remote areas can cause major system disturbances as evident with the catastrophic blackouts that occurred in the Northeastern United States and Canada on August 14, 2003 and on the West Coast in August 1996. The increasing threat of these large-scale system disturbances makes using wide-area measurement systems to monitor large grids more urgent than ever before. Phasor Measurement technology is proving to be a promising new tool that enables real-time system monitoring and reduces the probability of major disturbances
