摘要
An analysis method of coal consumption of the thermal power unit during peak shaving transients includes measuring and recording the coal-feeding rate under different steady-state loads, and then establishing the relationship between the coal-feeding rate and the load, wherein the coal consumption index of the unit during transients can be directly presented by the difference between the real-time coal-feeding rate and a steady-state corresponding value; the total coal increment can be obtained by integrating the real-time coal-feeding rate increment with time; for different loads, the coal consumption increment due to the unit's thermal storage variation can be defined as the thermal storage coal consumption increment; the thermal storage deviation of the unit during transients causes the additional coal consumption, which is defined as the process control coal consumption increment. This work can provide the clear guidance for the fuel control of the thermal power unit during peak shaving processes.
