<p>PROBLEM TO BE SOLVED: To provide a method for determining one or more weak buses in an electrical power system.SOLUTION: The method includes computing voltage stability indices (VSIs) corresponding to a plurality of buses in the electrical power system as a function of phasor values associated with the plurality of buses and a reference phase angle corresponding to one of the plurality of buses. The phasor values include either (a) a voltage magnitude (V) and a phase angle (δ), both corresponding to each bus, or (b) change or a rate of change of the voltage magnitude (ΔV), and change or a rate of change of the phase angle (Δδ), both corresponding to each bus. The method further includes identifying one or more weak buses from the plurality of buses in the electrical power system on the basis of the computed VSIs.</p> |
