| Abstract: | Combined with different operation states of the 600 MW turbine-generator unit in a power plant,significant torsional fatigue life loss will occur owing to the permanent single-phase failure and unsuccessful automatic reclosing occurring on the transmission line terminal close to the power plant bus bar.Calculation & analysis have been made based on a large amount of cases by using the multiple run component of PSCAD/EMTDC in the electric system repeatedly to carry out simulation automatically.Results show t... |
