“…The adopted six-pulse SVC (see Figure 2) comprises a thyristor controlled reactor (TCR) and a passive inductor (L) and capacitor (C) filter tuned for the fifth harmonics. Unlike previously reported work [4][5][6][7][8][9][10][11] where SVC was installed at generator terminals, here it is connected to the high-voltage (500 kV) side of the plant through a step-up transformer. Reasons for this include (i) the enclosed bus bar linking the generators and the main transformer is not allowed to open for the insertion of an SVC to avoid deterioration of reliability, (ii) preliminary comparative studies indicated that the position of SVC does not affect the damping effect significantly, and (iii) one or two large SVCs connected to the common bus, instead of four smaller ones at generator terminals, will save cost, room, and operational maintenance.…”

“…The first experience of SSR occurred at the Mohave station in the early 1970s. To prevent recurrences of similar incidents, various measures have been proposed, such as the excitation controller [2,3], the blocking filter [2] and various FACTS controllers reported recently, including static var compensator (SVC) [4][5][6][7][8][9][10][11][12], thyristor controlled series capacitor (TCSC) [13], STATCOM [14], and static synchronous series compensator (SSSC) [15]. The dynamic stabilizer proposed by Ramey et al [4] was the first application of SVC to the SSR problem.…”

SUMMARY An optimal subsynchronous damping control (SSDC) of static var compensator (SVC) is designed using genetic algorithm and simulated annealing, to mitigate the multimodal subsynchronous resonance of a practical multi‐machine series‐compensated transmission system. The SSDC comprises independent modal control paths, each with separate feedback gains and phase shifts, to damp various torsional modes. The control‐design task of simultaneously tuning all the control parameters for robust stabilization of multiple torsional modes under various system conditions is formulated into a constrained optimization problem, which, by using the proposed genetic algorithm and simulated annealing, is efficiently solved and the SVC‐SSDC optimized. Eigenvalue analyses on the basis of the electromagnetic system model as well as real‐time digital simulation using the DSP‐implemented controllers have been conducted on the test system to validate the proposed approach and the designed hardware SVC‐SSDC.

This paper briefly introduces the first project in China using a Static Var Compensator (SVC) to damp Sub-Synchronous Oscillations (SSO) excited by fixed series compensation. Since the SVC function of this project is to damp SSO, it is necessary to study its side-effects on the ac system when damping SSO. A real time digital simulator (RTDS) model for this project is developed and a closed-loop test platform is established, which is comprised of an RTDS and a physical SVC controller. Based on the platform, this paper studies the side-effects of the SVC including transformer overload, ac system transient stability and relay malfunction. Simulation and theoretical results show that all these sideeffects are acceptable and will not effect the operation of the ac system.
