A block diagram of the controller and TSSC models is shown in Fig. 8. The controller utilizes only locally measured quantities measured at the TSSC location. Generally, a fault in the system first leads to a risk of transient instability, which initiates the transient controller. When this controller has performed its sequence, there is commonly a power oscillation in the system, which is detected by an RLS algorithm [20]. The RLS algorithm is based on the assumption that the line power is composed of a zero frequency component (the average value) and a component, which has a known frequency range (the dominant power oscillation frequency). The algorithm utilizes an expected oscillation frequency when no oscillations are at hand. At any event that causes power oscillations, the frequency parameter is adapted to the actual oscillation frequency by a PI-controller. The algorithm gives a real-time estimation of the average line power , oscillation amplitude , frequency , and phase . The RLS algorithm is necessary in order to determine the input and timing for the damping controller and the parameter estimator. The bandwidth of the RLS algorithm is determined by the demands of the controller, which state that it is necessary to gain information of the oscillation phase and amplitude as well as the average value of the line power within one half of a power oscillation cycle after a step in the TSSC reactance. A higher bandwidth naturally means faster response but also a larger sensitivity to noise. The RLS estimator used here has been tested with a noise level of 1% of the input signal with good results
