“…Thus, to utilize its controllability in an economic fashion, a hybrid or dual form of compensation is recommended in [8,11] which employs series capacitor banks in conjunction with the SSSC. The SSSC model used for studies in this paper was originally proposed in [12] and has been used by other researchers for power flow control studies in [13][14]. The introduction of an external damping controller around the SSSC based on this scheme was presented in [15] to only damp the low frequency inertial mode of oscillation in a power system.…”

This paper investigates the effectiveness of a supplementary damping controller around a Static Synchronous Series Compensator (SSSC) in mitigating the torsional oscillations due to interaction of series compensated transmission line with the nearby turbine-generator shafts. The main objective of the controller is to suppress the unstable torsional oscillations with frequencies coinciding with the turbine-generator shaft torsional modes, through modulation of the reactance provided by the SSSC. Detailed simulation studies are done in Power System Computer Aided Design (PSCAD) using a single machine infinite bus (SMIB) power system adopted from the IEEE first benchmark model (FBM) for subsynchronous resonance analysis. The results show that this supplementary damping controller can provide positive damping to the unstable torsional oscillations due to presence of conventional series capacitors in the line or an SSSC or a combination of both the SSSC and conventional series capacitor banks.

“…In [9], small signal performance of the power system has been shown to be improved by controlling the damping characteristic of power system by controlling the operation mode and response time of FACTS controller. Hence, taking this advantage of FACTS controller, their capability to influence SSR mitigation has been assessed in [10]. This paper investigates the capability of SSSC to mitigate SSR.…”

Series compensation in transmission line with fixed series capacitor may cause Subsynchronous Resonance (SSR) at certain compensation level. This paper presents the application of static synchronous series compensator (SSSC) to mitigate impact of SSR. For analysis of SSR, IEEE first benchmark model is used and SSSC is located in transmission line at generator end. The linearized state space equation of SMIB system without and with SSSC has been developed to carry out eigenvalue analysis to identify potential modes for SSR. The AVR and PSS in the generator control loop coordinated with SSSC can successfully mitigate SSR. Time domain simulation is also carried out to confirm the results obtained with eigenvalue analysis.

“…The generators which could be adversely affected by interaction with a series compensated network, are to be determined and modelled in detail for digital simulation studies [5,6]. Wide range of investigations has been carried out for SSR countermeasures resulting in various methods to eliminate or mitigate the problem [7][8][9][10].…”
