PJM provided members a glimpse last week of the new visualization tools that will soon be available to transmission operators as a result of the deployment of synchrophasors.

The Real Time Dynamics Monitoring System will provide wide area situational awareness data to help analyze system performance & events. It will include several measures of grid dynamics, including phase angle differences (grid stress); small signal stability (oscillations & damping); frequency instability; generation-load imbalance; power-angle sensitivity and power-voltage sensitivity.

TOs will be offered training on the tool Feb. 28.

PJM officials said they will consider in the System Operations Subcommittee whether generator owners, which are being required to installed synchrophasors, should also have access to the system.
