摘要
辅机故障快速减负荷(RB)功能的可靠性对于防止机组非正常停机、提高电网稳定性具有重要意义。在众多RB试验项目中,一次风机RB是其中难度最大一项,对于无脱硫旁路挡板的机组,一次风机RB试验极易失败。通过采取各种改进措施,使一次风机RB各项指标均有较大安全余量。
The reliability of Running Back （RB） is meaningful for preventing disorderly closedown of plant and improving stability of power grid. The RB of primary air fan is the most difficult test .The K8 of the primary air fan is easy to fail in the plant without bypass of desulphurization system. After some improvements, the RB of the primary air fan have more safety margin.
