“…At any given machine, proper AVR and PSS designs in appropriate frequency ranges to achieve the limits of transient stability and oscillation stability require minimum adverse interaction between AVR and PSS devices. This also accords with industrial experience of PSS tuning, where a limit on the lower frequency gain of the stabilizer is necessary during changes in power set point at the price of reduced stabilizer performance [8].…”

“…It is observed in (8) and (10) that, compared to the previous AVR designs used in design C, the gains of and are increased at low frequency, but reduced at higher frequencies by the additional lag-lead network. By means of the PSS/AVR tradeoff, this allows improved PSS design with higher gain in the vicinity of 5 rad/s, the frequency of the interarea mode.…”

A step-by-step coordinated design procedure for power system stabilisers (PSSs) and automatic voltage regulators (AVRs) in a strongly coupled system is described in this paper. It is shown that it is possible to separate the design of individual PSSs and separate the design of individual AVRs. Thereby, the designs of AVR and PSS devices at a given machine can be coordinated to achieve near-optimal overall power system stability performance, including oscillation stability performance and transient stability performance. The proposed coordinated PSS/AVR design procedure is established within a frequency-domain framework and serves as a most useful small-signal complement to established large-signal transient simulation studies.Index Terms-Multimachine systems, oscillation mode stabilization, power system stabiliser (PSS) and automatic voltage regulator (AVR) design, transient stability.

Absfracf-This paper describes the characteristics of a new power system stabilizer, the Multi-Band PSS. Its model, IEEE PSS4B. is presented to explain its basic principles and functions. This Delta-Omega PSS makes use of three distinct working hands to process the whole spectrum of oscillating modes present in power systems. To illustrate the PSS performance, a simple setting technique, specifically developed for this PSS, is presented and used to validate the closed-loop performance of the MB-PSS either in stability simulations or field testing conditions. Presented results are for Hydrc+QuChec LGZ power plant.
