SSSC to control Power flow in the Line

FACTS controller is the Power Electronics based static controller which enhance power transfer capability and increase controllability of the power system network. Static Synchronous Series Compensator (SSSC) is VSC based controller which is used in transmission network with the aim of utilization of existing line upto its fullest extent. This paper demonstrates transmission line power flow control with the help of SSSC. A control scheme of SSSC is presented to control active power flow in the line. Increase in the power flow in the line is realized with SSSC operation in capacitive mode of operation and decrease in the power flow is realized with SSSC operated in inductive mode of operation. MATLAB simulation studies are demonstrated to validate the SSSC operation.

DISTRIBUTED STATIC SERIES COMPENSATOR (DSSC) APPLICATION TO POWER SYSTEM- A REVIEW

This paper is showcasing review of distributed static series compensator ( DSSC) & explains the effect of insertion of DSSC in transmission line power flow control. FACTS ( Flexible AC Transmission System) technology the aspect of Power Electronics offers High speed & reliability of switching & thus the value of electric energy is enhance. Along with merits there are certain problems offered by FACTS technology which leads to complexity in operation & overall cost investment becomes large. The solution to this is DFACTS technology i.e Distributed FACTS devices can be used in distributed position and DSSC belongs to DFACTS family.

Application of the interphase power controller technology for transmission line power flow control

This paper presents an application of the interphase power controller (IPC) technology for controlling power flows while maintaining the natural synchronizing capacity of transmission lines. The benefits for transmission systems are a substantial increase in steady-state transmission capability, lower losses and voltage support. An example based on the 500 kV Mead-Phoenix Project demonstrates the effectiveness of the IPC solution: the addition of a 370 MVAr capacitor in parallel with the two 500 kV phase-shifting transformers increases their maximum capability from 1300 to 1910 MW. The concepts presented are the results of the first phase of work leading to the development of an IPC using power electronics.
