【摘要】 水轮机调节系统参数整定一般常用绘制波德图或根轨迹图以配合现场调试。绘制上述图形虽可考察系统的稳定性和过程响应的特征值,但不能直观得到调节参数和动态的响应关系。 本文提供了按响应品质要求,通过计算机离线计算求取水轮机调节系统调节参数的辅助整定方法,能直观、准确地得到过程响应与调节参数之间的对应关系,为现场调试提供了有效的依据。更多还原

【Abstract】 Parameter presetting of a water turbine governor system is conventionally implemented by use of Bode-diagram or Root-locus plotting in conjun-ction with in-situ adjusting. Though the system stability and the characteristic value of response can be observed from the.plotting, yet it is impossible to find out directly the relations between regulated parameters and dynamic response. In order to obtain their real relation, this paper, according to the quality requirement of response, proposes a computer off-line computation method as an auxiliary means for presetting the regulated parameters of the water turbine governor system.更多还原
