Operations Applications
Blackstart and Restoration Procedure
assessment and review
System Operator Response Training
These are two very distinct applications
even though both are related to system
restoration

NERC System Restoration Guidelines
Consideration should be given to connecting shunt reactor devices to
help stabilize generating units being brought on line.
Transmission corridors for supplying start-up power should be
identified and switching procedures determined, taking extra care to
isolate damaged facilities.
Units without blackstart capability should be prepared to begin the
start-up process when start-up power becomes available.
Transmission system corridors to support the start-up process should
be established but not energized until needed.
As units with blackstart capability come on line, energize appropriate
transmission system corridors supplying start-up power for units that
are ready to return to service.

PowerWorld Simulator
Simulator is run in the Simulation mode
providing for chronological progression of
load flows as actions are taken on the
system
Lines are monitored for overloads
Contouring is used to monitor voltage levels

System Reconstruction
As the system is reconstructed, the island
swing bus will pick up load.
Other generation must be dispatched to
keep the swing bus from exceeding its
capacity.
Load must be added in small steps to
prevent collapse of the system

System Operator Response Training
Scenarios are created for which no specific
restoration procedure exists.
There are typically several right and wrong ways
to restore the system
Operators use NERC and company guidelines to
re-establish load and generation and resynchronize
where necessary
Additional system events are thrown at the
operators in the course of re-establishing the
system

PowerWorld Simulator as a Power System Simulator
EMS simulators can be in high demand. PowerWorld
Simulator can serve as a second simulator for certain
scenarios.
As the use of Retriever in the control room becomes more
widespread, Simulator becomes more valuable in training
operators and engineers in the use of PowerWorld graphics
in real time. Simulator can be used to develop displays,
voltage contouring and line monitoring for Retriever.
Simulator can be used to identify early warning graphical
signatures for potentially damaging events so that these
events can be avoided.
