摘要
随着火电机组汽轮机电液调节系统的大量应用,增强了汽轮机的可控性,提高了机组的安全性和热效率,其优越性日益表现出来。对于大容量火电机组CCS及DEH系统均设计有一次调频功能,尽管不同机组的CCS主控系统原理有所不同,但其一次调频原理相同。本文以山西古交电厂Ⅰ期工程2×300 MW机组为例,并根据火电机组汽轮机电液调节系统的特点,分析了一次调频的实质内容、实现策略和对机组的影响。
With a large number of applications of the electric hydraulic control system of the thermal power turbine,strengthen the controllability of the turbine,improve the safety and thermal efficiency of the unit.For CCS and DEH system of large capacity thermal power units are designed primary frequency modulation function,despite the principle of the CCS master control system of different units is different,but the principle of primary frequency modulation is the same.In this paper takes phaseⅠ2 × 300 MW units in Shanxi Gujiao power plant as an example,based on thermal power turbine electric-hydraulic control system features,analyses the he essential contents of primary frequency modulation,implementation strategy and the impact on the unit.
