摘　　要：根据先分析后综合的思想,本文提出了由基于数学模型的动态过程参数辨识检测各环节特性参数,系统仿真技术作整体综合的调速系统性能诊断方法。文中概要地介绍了调速系统性能诊断装置的系统激励、信号检测、参数辨识等硬软件结构与原理。Based on the principle of analyses first and synthesis second, this paper presents a perfor- mance diagnostic method for turbine governing system, which uses the mathematical model-based parametric identification of dynamic process to determine the characteristic parameters of each links and then to make the integral synthesis by systematic simulation. The structure and principle of the diagnosing device for turbine governing system are briefly described, such as systematic excitation, signal detection, parametric identification, etc.
