摘要
对于机组容量为1000 MW火电工程,当吸风机与脱硫增压风机合并,大容量辅机电动机的采用将导致高压厂用变压器阻抗选择困难。文章以汉川电厂三期扩建工程为例,通过对电厂负荷和接线的研究,提出了高压厂用电系统电压和接线推荐方案。
It is difficult to choose the auxiliary system transformer of 1 000 MW thermal power project,because of the combination of suction fan and desulphurizing fan, and adoption of large auxiliary motor. In this paper, authors take the case of third expansion project of Hanchuan thermal power plant, study the load and electric connection, finally confirm the voltage level and connection mode of electrical auxiliary system.
