Generator phase advance tests and data analysis for Xinjiang main grids

The characteristics of generator phase advance operation adopted by Xinjiang main grids in recent years are summarized through phase advance tests.Taking the data on phase advance tests for water turbine generators of Jilintai Hydropower Station and steam turbine generators of Manasi Power Plant as examples,the method of curve fitting was used to obtain the P-Q curve for generator phase advance operation and the fitting curve and fitting formulation for stator end temperature rise.The fitting effect was judged by the data on fitting errors.
