Use with the SEL communications processors, or the SEL-3530 RTAC, to change nonlinear state estimation into linear state estimation. If all necessary lines include synchrophasor measurements then state estimation is no longer necessary. The system state is directly measured. 10 Minutes 1 Second Figure 9 Synchrophasor Measurements Turn State Estimation into State Measurement Figure 10 Visualization of Phase Angle Measurements Across a Power System Improve Situational Awareness Provide improved information to system operators. Advanced synchrophasor-based tools provide a real-time view of system...
