Coincident with high-speed development of power grids in Anhui province, characteristics of power grids keep changing, and new requirements are put forward on the grid-related management of excitation system. This paper offers an overview of the characteristics of excitation system equipments and their operation in power grids of Anhui province. Based on field experiences, current management status are summarized, developments of the features of power grid and power source coordination related to excitation system are analysed. Considering from equipment security, the whole process management,dynamic stability of the grids, phase and voltage adjustment ability of generators, there is a need for enhancing the grids related management of generator excitation system, and the recommendations for improving devices reliability, ameliorating grid-related parameters management, damping strengthening of grids are presented.
