چکیده انگلیسی
According to the characteristics of utility-type generator set in variable load sliding-pressure operation, the paper comprehensively analyzes the features of feed-water system, in which variable-speed main feed-water and power frequency booster-pump connect first in series and then in parallel. It puts emphasis on fitting characteristics equation of feed-water pump under different operations, determining characteristics of feed-water pipeline under sliding-pressure operation, corresponding resistance coefficient, and finally deducing the equation of lift, efficiency and rotating speed when different loads and different sliding-pressures are adapted only by main feed-water pump variable speed adjusting. It takes one power plant 600MW supercritical unit for example to compare the energy consumption of different operation modes, and thus puts forward a more suitable operation mode under different loads, providing theoretical basis for the practical application of project.
