This paper proposes an adaptive dynamic Mho distance relay based on a phase comparator scheme for protecting interconnected transmission networks compensated with Thyristor Controlled Series Capacitor (TCSC). The proposed uses impedance index factor to initiate the fault detection subroutine. RMS of positive sequence current faulted loop and TCSC terminal are compared zone identification. A gro...

This paper presents a systematic procedure for modelling and simulation of a power system installed with a power system stabilizer (PSS) and a flexible ac transmission system (FACTS)-based controller. For the design purpose, the model of example power system which is a single-machine infinite-bus power system installed with the proposed controllers is developed in MATLAB/SIMULINK. In the develo...

Improving of ATC is an important issue in the current de-regulated environment of power systems. The Available Transfer Capability (ATC) of a transmission network is the unutilized transfer capabilities of a transmission network for the transfer of power for further commercial activity, over and above already committed usage. Power transactions between a specific seller bus/area and a buyer bus...

This paper proposes a hybrid controller scheme for enhancement of steady state stability in the presence of uncertainties in power systems. The procedure employs a robust TCSC assisted by a Fuzzy PSS designed with the uncertain model of power system. The resulting controller provides excellent damping of oscillations at low frequencies for a SMIB system. The Simulation results show the great en...

Power system engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. This is where the Flexible AC Transmission Systems (FACTS) technology comes into effect. With relatively low investment, compared to new transmission or generation facilities, the FACTS technology allows the industries to better utilize the existing transmission an...
