NOVEL TSI SYSTEM FOR MONITORING AND PROTECTION OF TURBINE GENERATOR SET AND INNOVATIVE OPTIMIZATION METHOD THEREOF

A novel TSI system for monitoring and protection of a turbine generator set and an innovative optimization method thereof are disclosed according to the present application, which belongs to a monitoring and protection device for important industrial equipment. Through innovative optimization of in-site primary detection elements for vibration, shaft displacement and the like in the TSI system, a device framework inside a TSI protection disk, a power supply, card and channel, a signal output relay and the like, effective dispersion and mutual redundancy of the above elements can be achieved as much as possible. In addition to the conventional method for realizing the protection logic with digital quantities, it is also possible to realize the protection logic criterion configuration mode of median-out-of-three selection of analog signals in DCS-ETS controller, and it is also possible to realize more redundant protection logic configuration determination mode with combination of digital and analog quantities in DCS, which makes the protection logic configuration mode of the TSI system more flexible and reliable, effectively eliminates the faults such as abnormalities or disappearance of important monitoring signals of the TSI system that often occur in the conventional technology, and especially solves the problem of refusal-to-operate or misoperation of the protection device of the important equipment that brings a lot trouble to the industry.
