摘　　要：在发电机的并列方面有准同期并列与自同期并列两种方式,各有优缺点,从方便使用、实现自动化方面来看,自同期并列的优点要多些,但并列过程中仍存在一定的冲击电流。本文提出了一种基于开关变压器技术在水轮发电机自同期并列上的控制方案。该方案可有效减小自同期并列过程中的冲击电流,降低并列风险提升电网稳定性,电网长期高效稳定的运行。Proposed based on self-switching transformer in generator control scheme on the random synchronizing concatenation.In the generator has random synchronizing and quasi-synchronization in two ways from the same period,advantages and disadvantages.From the easy to use,automated ways,random synchronizing concatenation has more advantages,but there is still the process of the impact of current.The program can effectively reduce the impact during the same period of the current parallel,reduce the risk of random synchronizing concatenation to enhance grid stability,highly efficient and stable long-term operation of power grid
