Abstract: In accordance with one embodiment, a method for determining one or more weak buses (102, 104, 106, 108, 110, 304, 306) in an electrical power system (100) is provided. The method includes computing voltage stability indices (VSIs) corresponding to a plurality of buses (102, 104, 106, 108, 110, 304, 306) in the electrical power system (100) as a function of phasor values associated with the plurality of buses (102, 104, 106, 108, 110, 304, 306) and a reference phase angle corresponding to one of the plurality of buses (102, 104, 106, 108, 110, 304, 306). The phasor values include either (a) voltage magnitude (V m) and phase angle (.delta.m), both corresponding to the respective bus, or (b) change or a rate of change of the voltage magnitude (.DELTA.V m), and change or a rate of change of the phase angle (.DELTA..delta.m), both corresponding to the respective bus. The method further includes identifying one or more weak buses (102, 104, 106, 108, 110, 304, 306) from the plurality of buses (102, 104, 106, 108, 110, 304, 306) in the electrical power system (100) based on the computed VSIs.

Abstract: A phase identification system (70) includes a power distribution station (12) and a phase detection device (140). The power distribution station (12) includes a phase distortion device (72) for generating voltage distortions of a known harmonic frequency in at least one of three phase voltage signals of the power distribution station (12). The phase detection is configured to receive at least one of distorted three phase voltage signals and to identify a phase of the received voltage signal. The phase detection device (140) includes a delay circuit (144) to generate a phase shifted voltage signal of the received voltage signal and a transformation module (142) to transform the received voltage signal and the phase shifted voltage signal into d-q domain voltage signals of a known harmonic frequency reference frame. A phase determination module (154) in the phase detection device (140) determine the phase of the received voltage signal by comparing an amplitude of a harmonic of the known harmonic frequency in the received voltage signal with a threshold value.
