摘要
为降低汽轮机调节阀节流损失,根据调节阀流量特性试验,对机组配汽方式进行优化。配汽方式优化后,会部分削弱机组一次调频和自动发电控制(AGC)响应能力,为提高机组对电网一次调频和AGC的响应速度,提出一种凝结水参与机组一次调频和AGC的技术,在一定程度上提高机组升降负荷的能力,从而缓解电网考核对机组节能运行的制约,进一步降低调节阀节流损失,实现节能的运行目标。
To reduce steam turbine control valve throttle loss,steam distribution method was improved according to control valve flow characteristic test. After improvement,unit primary frequency modulation and automation generation control( AGC)responsiveness was weakened. To improve unit primary frequency modulation and AGC responsiveness,a technology that bring condensate water into primary frequency modulation and AGC was introduced. Unit capability of capacity variation was enhanced,and reduced control valve throttle loss. Energy saving operation was realized.
