摘要
一、问题的提出 设发电厂有n台凝汽式汽轮机组,采用中央集中供水,各机循环水量为W_i,总循环水量为W_0,则W_0=W_1+W_2+…+W_n,并设W_0为一常量。设n维向量W=(W_1,W_2,…,W_n),则W可表示n合机组间循环水量的分配状况。设各机组仅有循环水量W_i改变时,引起排汽压力P_(2i)相应变化,对应各机组功率增量为△N_i,总功率增量△N_∑=△N_1+△N_2+…+△N_n。当W变化时,引起△N_∑相应变化。
Following researches on optimum distribution of circulating water of power plants have been carried out in this paper. The steam turbine relationship of d(AN)/dW is derived. The condition of optimum distribution has been proved. The theoretical solution of Wu between two steam turbine sets or n sets has been presented, by which the distribution problems of circulating water of cogeneration plants can be solved on computer.
