This paper addresses the uses of the Dispatcher Training Simulator (DT
S) at PECO Energy. The primary applications of the simulator are discu
ssed from a users point of view rather than the technical details that
describe its internal workings. Topics addressed are dispatcher train
ing, engineering studies, Root Cause analysis investigations (why unde
sirable things happened) and the use of the DTS as a public relations
and confidence building tool. A discussion of the DTS training environ
ment and general training philosophy is included along with a step by
step progression through the development of a typical training exercis
e. A section is included that recommends changes in the implementation
of the DTS along with a ''Lessons Learned'' discussion. A sample DTS
lesson plan is included.
