一个良好的水轮机调节系统,除要求调节过渡过程快速收敛和运行稳定外,尚须有良好的静态质量。所谓水轮机调节系统的静态质量是指在调节过渡过程终了之后,调速器测量元件(飞摆或电液转换器)的频率变化f与接力器活塞行程S_p之间的关系S_p=f(f),及调节系统的不灵敏区ε_p。由于工业发展对电能质量的要求愈来愈高,一般电力系统频率要保持在50±(0.1～0.2)赫芝,因此就要求水轮机调节系统能准确地工作,也就是要求S_p=f(f)呈线性关系和不灵敏区ε_p≤±0.1赫芝。为了满足这些要求,在设计、安装与维护时,必须对水
A good turbine regulation system requires a good static quality in addition to the fast convergence and stable operation required to regulate the transition. The so-called static quality of the turbine governing system refers to the relationship between the frequency change f of the governor measuring element (flying pendulum or electro-hydraulic converter) and the piston stroke S_p of the relay after the transition process is completed. S_p = f (f) , And adjust the system insensitive area ε_p. As the industrial development demands higher and higher power quality, the frequency of the power system should be maintained at 50 ± (0.1 ~ 0.2) Hz. Therefore, it is required that the turbine governing system can work accurately, that is, S_p = f (f) Linear relationship and insensitive area ε_p≤ ± 0.1 Heizhi. In order to meet these requirements, water must be designed, installed and maintained
