Computational and experimental test of self starting regimes for the in-house needs of the PGU-450 steam-gas unit at the Kaliningrad TÉTs-2 Heating and Power Plant during supply disruptions

The major stages of a computational test of the self starting regimes for the in-house needs of unit No. 1 of the 450 MW steam-gas unit at the Kaliningrad TéTs-2 Heating and Electric Power Plant during supply disruptions are described. The results of an experimental test of five regimes are described and compared with the computational data. The results are analyzed. Recommendations are made for changes in the automatic reserve switching algorithms for the 6-kV sections, which, when realized, will ensure easier self startup for the mechanisms providing for in-house needs during supply disruptions. __________ Translated from élektricheskie Stantsii, No. 4, April 2008, pp. 46–55.
