Long interruptions cause no compensable problems to the power systems and decrease the reliability
of the system significantly. One of new technologies that decrease the fault time is Static Transfer Switch (STS)
with alternative power supply. In this study an industrial plant with motor loads has been studied with and
without use of STS in front of a voltage fault. The simulations have been done to demonstrate the speed of the
motors during the faults. As the interruption duration is an important factor in reliability analyzing, some faults
with various durations have been applied to the system to study the reliability of the system with and without
STS. The results are given to verify the STS efficiency in increasing the system reliability by restoring the
motors’ speed drop in least time.
Key words: Industrial power system, long interruption, motor load, power system reliability, static transfer switch, ,
