“…While the effectiveness of a DTA index has already been verified [8][9][10][11][12][13][14][15][16][17][18], in this section, eigenvalue calculations are used to demonstrate the effectiveness of the proposed stabiliser-tuning strategy.…”

“…Then, the delivered damping torque is rendered from a specified oscillation mode by multiplying the eigenvalue sensitivity of the corresponding generator. DTA indices for a power system stabiliser (PSS), flexible AC transmission system (FACTS)-based stabiliser, static synchronous compensator (STATCOM)-based stabiliser and energy storage system (ESS)-based stabiliser are obtained in [11][12][13][14][15][16] according to the PhillipsHeffron model. They can be used to choose location [17], evaluate contribution [9], adjust parameter [18] and set the feedback signals of the stabilisers [8].…”

“…However, when the DTA is extended to the more general case of a multimachine power system, it becomes significantly complicated, even in a simple case that a power oscillation along a particular transmission line, such as tie line, is studied by using the extended DTA. This is because based on the concept of damping torque, contributions to every generator have to be taken into account such that the DTA applied in the multi-machine power system involves large number of generators [5]. This might be the reason why when multi-machine power system oscillation is investigated, often modal analysis (eigensolution-based methods) is the more favoured method than the DTA.…”

SUMMARYDamping torque analysis (DTA) is a well-developed technique for understanding and studying power system oscillations. It is established on the basis of physical explanation of damping torque contribution of power system control to the rotor motion of generator. Hence when it is applied in a multimachine power system, the DTA becomes complicated due to the involvement of large number of generators. In this paper, a graphical explanation of the DTA method is presented by using the small-signal equal-area criterion of power system stability analysis. The graphical explanation presented turns out to be completely independent of the physical concept of damping torque, indicating the significant potential to develop the graphical explanation into a general and simple approach for understanding and studying multi-machine power system oscillations. In the paper, an example of a multi-machine power system installed with a STATCOM (static synchronous compensator) is given to demonstrate how the potential of applying graphical explanation can be explored. Based on the conclusion drawn from the graphical explanation, it is shown why the STATCOM voltage control contributes little damping to power system oscillations and a simple method of designing a STATCOM stabilizer is proposed. Confirmation from simulation results of an example four-machine power system is presented in the paper.

This paper introduces a localized phase compensation method for the design of power system stabilizers (PSSs) to suppress the oscillation occurred in a single-machine infinite-bus (SMIB) power system. The proposed method is used to design stabilizers to suppress power system oscillations and only requires the available generator and transformer parameters thus eliminating the need to receive and verify entire power system parameters. This paper establishes the extended linear Phillips-Heffron model for a SMIB system with a PSS installed in the generator and demonstrates application of the model to determine damping and thus preserve power system oscillation stability. The paper also presents several examples where the proposed method has been used with two models to design PSSs with comparative results presented in a case study.
