Study On Quasi-synchronization Parallel In 1000MW Hydro-generator

1000MW hydro-generator has many advantages such as giant unit capacity, higher operation efficiency. By the research and development, 1000MW hydro-generator is got much attention. At present, 1000MW hydro-generator is currently under development. There is no precedent of 1000MW hydro-generator operated before in the world. The research and analysis of 1000MW hydro-generator by using the quasi-synchronizaton parallel in are got.The mathematical model of 1000MW hydro-generator which connected with the infinite system is established. By the analysis of the transient process of the hydro-generator by using the quasi-synchronization parallel in, the current and torque equation of this process are got. To be a theoretical basis for the admissible conditions of 1000MW hydro-generator by using the quasi-synchronizaton, this analysis is necessary.The current of 1000MW hydro-generator by using the quasi-synchronization parallel in should not exceed a half of the current by using the non-synchronous parallel in, the torque should not exceed the torque of the non-synchronous parallel in. Under the analysis of 1000MW hydro-generator by using non-synchronous parallel in, the admissible conditions of the current and torque of 1000MW hydro-generator by using quasi-synchronization parallel in are got.There are different influences of 1000MW hydro-generator, when the voltage amplitude difference, the phase difference, the frenquecy difference by quasi-synchronization parallel in existed. Firstly, the influences on 1000MW hydro-generator by the voltage amplitude difference, the frenquecy difference, the phase angle difference independly existing are analyzed. Then by the simulation analysis of all the possible the differences, the pulsant voltage's critical conditions of the largest impact on 1000MW hydro-generator by using quasi-synchronization parallel in are got.Through the analysis of by using quasi-synchronization parallel in, not only does provide enidence for the rational design and reliable operation of 1000MW hydro-generator, but also it is significant that other connected devices, electrical protection equipment are selected and used.
