In a long transmission line the use of static series synchronous compensation (SSSC) with fixed series capacitor enables fast control of power flow. There is a potential risk of subsynchronous resonance (SSR) due to the series capacitor. In this paper, we propose to use the Kalman filter (KF) for state estimation of subsynchronous components present in series compensated line and the mitigation of SSR. This novel KF based SSR damping controller is referred to as KF-damping controller. The design of KF-damping controller is based on the magnitude of damping torque in the range of torsional mode frequencies. We apply the genetic algorithm to optimize the controller parameters. The proposed KF-damping controller is highly frequency selective and effectively suppresses subsynchronous components of line current in the presence of close frequency oscillations. Analytical and simulation results at various system operating conditions demonstrate the effectiveness and robustness of the proposed KF-damping controller in mitigating SSR. © 1969-2012 IEEE.

Kalman Filter Based Detection and Mitigation of Subsynchronous Resonance with SSSC

IEEE Transactions on Power Systems

This paper presents, the SSR characteristic analysis of the system with combined active and passive series compensation methods to increase secure loading, stability and fast control of power in the transmission line. The hybrid compensation is done by considering SSSC (an active FACTS device) and fixed series capacitor (passive compensation) method. Also, the Flower Pollination Algorithm is adopted in designing of the SSSC with Type-1 controller based on the damping torque analysis. The SSR analysis is carried out using damping torque, eigenvalue and transient simulation methods which show the effectiveness of SSSC in the elimination of torsional interaction at the operating point. The SSSC with Type-1 controller shows better performance in reducing the network resonant frequency along with improved power transfer capability of line. © 2019 IEEE.

Analysis of SSR with SSSC using FPA based Voltage Controller

Hybrid series compensation using static synchronous series compensator (SSSC) and passive series capacitor can improve the stability of the system, increases the power transfer capability and is useful for the fast control of power flow. This paper analyzes the subsynchronous resonance (SSR) characteristics of the hybrid series compensated power system in detail and proposes a simple method for the extraction of subsynchronous components of line current using filter. The extracted subsynchronous frequency component of line current is used to inject a proportional subsynchronous voltage in series with the transmission line which suppresses subsynchronous current in the transmission network. This novel technique is termed as subsynchronous current suppressor. The design of subsynchronous current suppressor is based on damping torque analysis and using genetic algorithm. A novel graphical representation of series resonance condition when SSSC is incorporated in the system is presented. The detailed study of SSR is carried out based on eigenvalue analysis, transient simulation and damping torque analysis. The results of the case study on a system adapted from IEEE First Benchmark Model demonstrates the effectiveness and robust performance of subsynchronous current suppressor in damping of SSR under various system operating conditions. © 2012 IEEE.
