摘要
提高火电机组一次调频响应性能对电网稳定具有重要意义。1000 MW二次再热机组以滑压方式运行,为确保经济性,汽机超高调开度较大,加上机组带有较大的供热,机组的调频能力进一步受限。提出一种基于凝结水节流调频的控制策略,通过凝结水节流调节释放机组蓄热,从而增加额外的负荷,提高一次调频性能。
Improving the performance of primary frequency response of thermal power units is very important. 1000 MW double reheat units operate by sliding pressure,to ensure the economy,the opening of superhigh pressure cylinder regulating valve of the turbine is very large,the capacity of the primary frequency is further limited with heating supply systems. A frequency control strategy based on condensate throttling is presented in this paper, through condensate throttling release the accumulation of heat, thereby increasing additional load, improveing the performance of primary frequency modulation.
