| Abstract: | This paper presents diagnosing rules and models for 7 kinds of common faults on turbine control system.It describes charateristic signals,fault symptoms and diagnosing rules for the following faults:over speed of turbine rotor,shaking of governing system,incapability of maintaining turbine generator set runing on governing system,abrasion of main oil pump,abrasion of governing oil pump,downdrop of fractured control valve system,and fragmentation of control valve case.Fault diagnosis models based on the theory of reliability are illustrated as well as the calculating formulas of the above faults probability and some applications.
