135MW机组一次调频功能优化

介绍云浮发电厂#4机组一次调频功能的基本原理。通过试验,发现一次调频功能存在问题,经过分析,对控制逻辑和参数进行修改,解决了存在问题,并使DCS侧的一次调频功能与DEH侧的功能很好地配合,在不影响机组稳定运行下完全有能力参与一次调频。

135MW unit primary frequency modulation.to be optimizated

This paper introduces a basic principle of primary frequency modulation of function of Yunfu Power Plant.Through the experiments,We found some problems of the primary frequency modulation function.But through analysis,we solve these problems by modifying control logic and parameters,and make the primary frequency functions whicn of the DCS side and the DEH side to be cooperated well.It is fully capable of participation in primary pfequency modulation,without affecting the stable operation of units.
