摘要
发电机组一次调频功能是保证电网频率稳定的一项有效措施。本文结合河南省一次调频考核开始后对火电机组一次调频治理情况,从信号采集、逻辑控制、执行系统和信号传输4个环节对影响火电机组一次调频合格率的问题进行了归纳、分析和总结。实践证明,通过对这些问题的系统排查和治理,可以有效提高机组一次调频合格率,在满足电网要求的前提下,赢得更多的发电机会。
The factors influencing the passing raie of primary frequency regulation of thernlal power units are categorized and analyzed from four aspects of signal acquisition, logical control, actuator system and signal transmission. After these factors are detected and tackh,d in the running units, the passing rate of primary frequency regulation is effectively improved. When meeting the requirements of the power grid. the units will be able to gain more generation opportunities.
