Abstract

To research the influence of thermal control strategy on the energy consumption characteristics of coal-fired power plants in peak load regulation process, a model of 660 MW coal-fired supercritical power unit coupled with its control system was established. The key parameters of the unit and its characteristics of energy consumption in load regulation process were calculated and analyzed under water follow coal (WFC) and coal follow water (CFW) control strategies. The results showed that CFW control strategy has advantages over WFC in live steam pressure control, the cumulative deviation of live steam pressure with CFW is less than that with WFC; but CFW does not show superiority in live temperature control, and its cumulative deviation of live steam temperature is larger than that with WFC. The supercritical unit with CFW control strategy can make full use of its energy storage in load regulation process. A supercritical power unit with CFW control strategy has a higher energy conversion efficiency than WFC control strategy in transient loading variation process, and its average standard coal consumption variation rate is smaller with a maximum deviation of 0.69 g· kW^-1·h^-1 in our research.
