Analysis of excitation system of No.6 unit of Tianshengqiao hydropower station

The No. 6 generating unit of Tianshengqiao No.2 hydropower station is quipped with a computerized shunt excitation silicon controlled rectification and excitation system. This system is supplied by Austria's ELIN Company and has tow sets of computerized excitation regulators, one is used for operation, another is kept in reserve. This system also has a 4-branch parallel fully-controlled rectification circuit. These excitation regulators have tow operating modes: manual and automatic operations. This paper presents in detail the composition, advantages and applicability of the excitation system. The system is characterized by its complete functions, flexible operation, stable and reliable performance, and minimum maintenance amount.
