During the design and construction of Lijiaxia Unit 5,a large number of innovative technologies were adopted. Fiber optic temperature monitoring was used in key areas such as the stator winding and iron core of the unit,achieving an upgrade from"electrical temperature measurement"to"optical temperature measurement"in the stator area of the hydro-generator.In particular,the stator winding all adopted a new replaceable temperature measurement structure,which was still the first time in the industry.This paper reports the technical scheme and construction process of fiber optic tempera-ture monitoring for Unit 5 of Lijiaxia,and su mmarizes the key points to be paid attention to during the debugging process of fiber optic temperature monitoring system for large water turbine generator units.It can provide valuable reference for subsequent projects to adopt such technology.
