Control and simulation of static condenser

Abstract

A static condenser is an advanced Static VAR Compensator (SVC) using voltage source converters with capacitor connected on the DC side. It has several advantages over both rotating synchronous condensers and variable impedance type SVCs and is expected to make a major breakthrough in the reactive power control in electric utility systems. This paper presents the mathematical modelling and asalysis of static condenser. The control parameters are based on eigenvalue analysis and the performance evaluated from digital simulation. The results from a case study show the benefits of static condenser in improving system stability and thereby increasing the power transfer in the line.

“…The value of is 145 and is 1.0. Table XI shows the variation of for different locations of TCSC and STATCOM when there is a fault in line [8][9]. The value of is 160 and is 1.0.…”

“…Generally one of the generators with large inertia (say, the th one here) is considered as the reference, and the relative rotor angle of the th machine is found as - [10], [14]. The sensitivity of with respect to is computed as (8) However, individual speed deviation is considered here (and not relative speed deviation) because of the nonzero damping.…”
