Abstract
Electric power systems throughout the world are considerable changes due to
the converging forces of degradation, technology revolution and evolving customer
expectations. Quantitative reliability evaluation plays an important role in the
development, design and operation of composite generation and transmission or bulk
power systems.
This thesis presents research conducted on the development and examination of
concepts, techniques and pertinent factors in the reliability evaluation of composite
power systems.
Analytical method is used in this research to assess composite system reliability.
The system reliability was measured through reliability indices output ofETAP software
on reliability test system RBT (6bus) and the effects of station related outages are
combined with the connected terminal failure parameters. RBTS was augmented with
different configurations of substations (Ring bus-double bus double breaker- one and one
half circuit breaker-one and one third circuit breaker) and reliability analysis was run for
each configuration.
This thesis presents two mam contributions. First, is determine the value of
switching time, that is the time in hours for isolating a fault occurred at the component,
on the calculation, which proved it’s influential in improving reliability indices.
Second, the sensitivity analysis was run and shows the reliability indices of the
RBTS with different configurations of substations. The failure parameters of the circuit
breakers and bus bars are varied in order to observe this effect on the composite systems
