Damping for the Northwest - Southwest Tieline Oscillations - An Analog Study

Enhancement of Power System Dynamic Stability by Designing a New Model of the Power System

“…It has been observed in the tie-line connecting the large Pacific Southwest and the Pacific Northwest in the United States. It has also been observed on the tie-line connecting the northern Midwest and Canada [3,4].…”

“…(10)(11)(12) should be interred in Eqs. (1)(2)(3)(4) and then are linearized around a certain operating point. Hence, linearization of these equations around a certain operating point results in constants 1 1 2 2 3 3 4 , , , , , ,…”

Study on Oscillation Damping Effects of Power System Stabilizer with Eigenvalue Analysis Method

“…Power system oscillations were first reported in northern American power network in 1964 during a trial interconnection of the Northwest Power Pool and the Southwest Power Pool (Schleif et al, 1966). Up to now, generally speaking, power oscillations could be divided into three kinds of types, that is, local mode, inter-area mode, and global mode.…”

Effects of system nonlinearities on synchronous machine control

“…Park's equations (96,97), is the use of analog computers and provides a more detailed representation of the synchronous machine (2,3,10,13,79,87,109,110,115,116,118,119).…”

“…The "induced" damping is usually not enough to combat the problems of stability and control of a power system. An evidence of this is the existence of extensive literature on how to best produce "forced" damping (14,34,44,57,59,77,91,(111)(112)(113)(114)(115)(116)136).…”
