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...

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...

The paper reviews modeling of thyristor–controlled series capacitors (TCSC) which are highly nonlinear systems with continuous and discontinuous states, and proposes three nonlinear controllers for it: (1) An approximate feedback linearization control (FLC) (2) A sliding surface–like design (3) Control in transformed coordinates. Detailed (switched) time– domain simulations are used to verify t...

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...

The problem regarding the optimal placement and sizing of different FACTS (flexible alternating current transmission systems) in electrical distribution networks is addressed this research by applying a master–slave optimization approach. analyzed correspond to unified power flow controller (UPFC), thyristor-controlled shunt compensator (TCSC, also known as thyristor switched capacitor, or TSC)...
