本文强调了水轮机调速系统零点的作用,介绍了综合主导极点的概念。在综合考虑系统零点和极点作用的条件下,给出了根平面上极点的一个区域,并对两类水轮机调速系统进行了相对稳定性分析,得到了比绝对稳定域小得多的相对稳定域。
This paper emphasizes the role of zero point in turbine governor system and introduces the concept of integrated dominant pole. Considering the system zero point and pole function, a region of poles in the root plane is given. The relative stability of two types of turbine governor system is analyzed. The stability is much lower than the absolute stable region area.
