Keynote Paper: Technical and operational issues involved in the two shifting of power plant - salient features of a recent study by ETD

摘要

The author (ETD) pointed out that although the review had concentrated on coal- and oil-fired steam plant, nowadays many of the older combined-cycle plants were required to two-shift at short notice. Hence, although the focus of the presentation would he on steam plants, it would also look forward to a forthcoming review by ETD on combined cycle systems.In a preamble, the author stated that energy conservation measures, such as apartment and industrial combined heat and power (CHP), contrary to expectations, would increase the need for cycling, since such units tended to produce the equivalent of base load power. Peaks in demand would be imported from the Grid. If there were swing back to nuclear power, this too would tend to take up the base load, although he understood that in France PWR plants were permitted to load follow to a much greater degree.
