Design and realization of turbine steam unit vibration condition monitoring system

By monitoring a 600MW steam turbine generator unit, its structure is analyzed to acquire the parameters which are used for keeping the safety of steam turbine generator unit and their value ranges. We constructed the functional diagram of condition monitoring and fault diagnosing system for steam turbine generator unit, which functions are described in detail as follows. By applying various kinds of time domain and frequency domain methods to analyze the acquired vibration data, many figures information are obtained. Through the information, the status of the steam turbine generator unit can be better mastered. At last, with the data acquisition system and software LabVIEW of National Instrument Company (NI), some functions of this system, such as data acquisition, data analysis, status monitoring and so on, are verified on rotor test equipment. The verification proves the feasibility and effectiveness of the condition monitoring and fault diagnosing system for turbine steam unit.
