Delayed-Input Power System Stabilizer using Supplementary Remote Signals

Mode selective damping of power system electromechanical oscillations for large power systems using supplementary remote signals

“…The generators are represented by their fifth-order models. Moreover, for all simulation studies as well as for the PSS design, the structure of the ith-generator together with an n th ci -order PSS controller in a multi-machine power system given in [12] is considered.…”

“…After augmenting the controller in the multi-machine power system, the overall extended system equations for the system can be rewritten in a compact form as follows [12]:…”

“…This paper deals with the design of local decentralized PSS controllers using remote signals as supplementary inputs, for a better damping of inter-area oscillations in a large-scale power system, in a manner that each decentralized PSS controller is designed separately for each of the inter-area modes of interest. The basic architecture [11,12] used in this work is shown in Fig. 1.…”

Mode Selective Damping of Electromechanical Oscillations in Power Systems Considering Time Delay Uncertainty of Input Signals

“…After augmenting the controller in the multi-machine power system, the overall extended system equations for the system can be rewritten in a compact form as follows [8]:…”

“…3. PSS inputs are formed by measured variables coming from the whole system, i. e., also from remote generators [8]. Thus, each PSS receives more complete measurement information about the inter-area oscillations to be damped.…”
