Σύνοψη

Planning the operation, improvement and expansion of power
system requires studies of the stability of the system and
protection against lightning and switching surges and
against short circuits.
Interconnection of systems increases the amount of current
which flows when a short circuit occurs on a system and
breakers are required, able to interrupt large current. The
disturbance caused by a short circuit on one system may
spread to interconnected systems and instability results to
all of the system unless proper relays and circuit breakers
are provided at the point of interconnection.
The main purpose of this work lS to conduct transient
stability studies on VAX computer to determine the
appropriate minimum relay operation times under fault
conditions on the E.A.C. transmission system. By
controlling the switching operation and the sequence of
fault, swing curves of machines were plotted on common axis
and conclusions were drawn, on the stability of E .A. C.
transmission system. The examination was carried out under
1.00 sec time period study and during this time it was
obvious when the system was stable or unstable.
