The advantages and disadvantages of temperature measurement of unit resistance temperature detector for TGP power station are analyzed. The principle and characteristics of fiber temperature measurement are introduced. Through the installation of optical fiber temperature measurement device in the busbar assembly, the accuracy, stability and system functions of optical fiber temperature measurement are analyzed. The analysis results show that the optical fiber temperature acquisition accuracy, good stability, to meet the Three Gorges Hydropower Plant online monitoring system requirements. Through the test, the possible problems of installing the real machine were found, and the solutions were put forward. The conclusion was reached that the optical fiber temperature measurement could meet the temperature measurement requirements of the units of the Three Gorges Left Bank Power Station and could be installed in real machine.
