火电机组一次调频性能提升实践

Practice of Improving the Performance of Primary Frequency Regulation of Thermal Power Unit

发电机组一次调频功能是提高电网应对突发扰动能力、改善电网频率稳定性的重要手段。通过采取网厂信号同源、阀门流量修正及主汽压力校正等措施,对一次调频装置进行了改造,有效提高了火电机组一次调频能力。

The primary frequency regulation function of the generator unit is one of important means to improve the power grid＇s ability to respond to sudden disturbance and the frequency stability of power grid.In this paper,by adopting the measures such as signal homology,valve flow correction and main steam pressure correction,the primary frequency regulation device has been transformed to effectively improve the primary frequency regulation capability of thermal power units.
