System Parameters
The bus voltage, transformer tap setting, line and transformer data, real and reactive power for load
and generation are specified in actual unit unless stated in per unit which are derived based on 100
MVA and corresponding voltage level.
System Performance
System performance such as bus voltage magnitude, generator/transformer/line loadings, losses etc. will be
affected by contingency event or network changes in power system such as:
a) Generators tripping or not available or different setting.
b) Shunts capacitors tripping or taken out for maintenance.
c) Transformers tripping or taken out for maintenance or change in tap setting.
d) Lines tripping or not in service or change in size or length.
e) Others or any combination of above.
Contingency Scenario
The contingency scenario occurs as follows:
1. Generators at REDBUD69 and CEDAR69 are still under long outage.
2. The 2nd 138/69kV transformer at the PEACH substation is under maintenance and taken out of
service.
3. After one hour later the 69kV transmission line between OLIVE69 and CHERRY69 tripped on
a permanent fault.
Task
During the contingency scenario, discuss the system performance in terms of bus voltage magnitude,
generator/transformer/line loadings, losses etc. Explore the possible actions to be taken in order to bring back
the system to normal operating condition. Support your remedy actions with PowerWorld Simulator 19 GSO
simulations results.
