Research on Synchronous Generator Automatic Quasi-synchronizing Device

摘要：

The generator synchronizing is an important and frequent operation in the power system.A new-style generator quasisynchronizing device based on AT89S52 SCM and CPLD is studied in this paper.In order to avoid great impact current,the voltage magnitude,frequency and phase difference between two sides of the breaker must be permitted,otherwise the frequency and the voltage of the generator will be adjusted.The AT89S52 and CPLD act as the core in the hardware design and the hardware includes eight modules.The configuration program idea is adopted in the software design which includes main program and many subprograms.The structure of the device is simple,the reliability is high and the maintenance is easy.The measures of the frequency,voltage and phase are automatically finished and the intelligent frequency and voltage adjustments are realized in the new synchronizing device.The simple interface makes parameters setup simply and neatly.The functions of the sample are steady and dependable after running for several months.
