Use of Thyristor Controlled Series Capacitors (TCSCs) to enhance power system transient stability and their possible application on the South African Grid

This research report is submitted as a partial fulfilment of the requirements for a
Master of Science degree in Electrical Engineering (Power). / Thyristor Controlled Series Capacitors (TCSCs) are FACTS devices which
incorporate power-electronic-based and other static controllers to enhance
controllability and increase power transfer capability. This research investigated the
possibility of applying TCSCs on the South African transmission network, in
particular application on long transmission lines connecting bulk thermal generators
in the northern part of South Africa to load centres located hundreds of kilometres
elsewhere in the country. The investigation, conducted using PSS/E (a power
system analysis software) demonstrated that application of TCSCs on this part of
South African transmission network results in improved transient stability margins.
The resulting improvement in transient stability is comparable to other transient
stability enhancement options like addition of transmission lines, thus the use of
TCSCs can be considered as an alternative. Further studies would be vital to
understand the interaction between Power System Stabilizers (PSSs) and TCSCs in
order to ensure proper tuning and interaction amongst the devices. / MT2017
