Abstract:
 In order to solve the problem that synchronous generator leading phase operation can enlarge the
power angle,which will impact system stability,firstly the type QFQS-200 large turbine generator leading phase
system simulation model is set up by MATLAB /Simulink software. Then with 100 %,80% and 60% load
conditions, the generator simulation model converts lagging to leading power factor state. And we can get the
characteristics of single generator leading phase operation. Compared with the simulation results,the data of the
same type generator unit under the same working condition,verify the accuracy of the proposed model. Afterwards,
the depth in phase simulation of the generator model with 60% load is carried out,and the results show that the
deeper generator in phase the more power angle oscillations is, the system stability will lose, too. Making sure
generator operation under the optimal phase depth is necessary. Finally,multi-generators leading phase system
simulation model is established,and the model is used to simulate the leading phase operation. It is concluded that
the multi-machine in-phase can avoid the single unit getting deep in leading phase,and have good stability.
