Analysis and Improvement of Power System Security by Placing Series FACTS Device

Authors(3) :-Nahid Khan, Ishraque Ahmad, Mohsina Anjum

Stressed power system, either due to increased loading or due to severe contingencies, it will lead to situation where system no longer remains in the secure operating region. Under these situations, it is primary objective of the operator to apply control action to bring the power system again into the secure region. Any delay or unavailability of suitable control leads to the unstable system. In fact, contingencies results into voltage limit violations and leads to overloading of lines. The system overloading can be recover by two alternatives firstly by restructuring the power system and secondly by controlling the line parameters. The Power system restructuring requires expanding unused potentials of transmission systems but environmental, right-of-way, and cost problems are major hurdles for power transmission network expansion. Nowadays, FACTS devices are used as an alternative to reduce the flows in heavily loaded lines, it will results in an increased loading, low system loss, improved stability of the network, reduced cost of production. In this paper, first contingency conditions are analyzed after that according to severity of contingency a real power flow performance index (PI) sensitivity based approach and the line outage distribution factor has been used to decide optimal location of series FACTS device, Thyristor controlled phase angle regulator(TCPAR) to restabilize the system. The effectiveness of the proposed controller has been tested on modified IEEE 14 bus system using Power world simulator 12.0 software.
