| Abstract: | By means of analyzing a unit trip incident of Shuibuya Hydropower Plant,the low oil pressure accident signal caused by PT primary fuse failure and over-excitation protection action signal of unit is illustrated in detail from governor system and excitation system. The governor system,the excitation systems and the unit exit PT are improved and upgraded after tripping incident,which has reference and guidance for secure and stable operation of hydropower plant. |
