A monitoring system for leading phase of generator based on Beidou satellite system is produced, which includes Beidou satellite system module, power angle calculation module, parameter identification module, interface change module, display module, and so on. On the method of generator power angle calculation considering flux saturation and parameter identification based on Thevenin equivalence, the monitoring system of the power plants and stations for leading phase operation of generator is formed. The relatively accuracy is high for on-line identification system parameter with saturation. The system which is proposed in the paper can be conveniently embedded into the existed generator monitoring system, especially for the power angle calculation module and parameter identification module by software programming.
