ABSTRACT
The equivalent circuit parameters of many power system components are described in other sections of
this handbook. The interconnection of the different elements allows development of an overall power
system model. The system model provides the basis for computational simulation of the system
performance under a wide variety of projected operating conditions. Additionally, ‘‘post mortem’’
studies, performed after system disturbances or equipment failures, often provide valuable insight
into contributing system conditions. This chapter discusses one such computational simulation, the
power flow problem.
