The SpaceTime Insight Transmission and Distribution Intelligence solution helps Entergy operations personnel monitor the real-time state of the grid and receive early warning on developing oscillation and voltage instability patterns and events. The system visualizes real-time data from high speed synchrophasor sensors, deployed throughout the grid, that sample data thirty times per second. Analyzing over 75 billion records per month, the software informs operators of disturbances on the grid in real-time, giving them precious seconds to respond to potential crises.
