失步发电机组的再同步机理

文章介绍了中国电网在电力系统发生失步振荡时，通过适当调控措施实施发电机组再同步以保持系统完整性的经验，并经严格理论推导，详细阐述了失步发电机组的再同步机理和条件，随后结合实例说明了失步发电机组的再同步的过程。在此基础上本文提出了为实施再同步发电机组保护、控制的优化工作建议。

Mechanism of the Resynchronization of Out-of-Step Generator Sets

The experience of generator resynchronization in China is presented by some appropriate control measures to keep the integrity of power systems after the power system lost synchronism and is under the asynchronous oscillations. By the strict theoretical derivation, the mechanism and the necessary conditions to resynchronize the generators under asynchronous operation are also presented. Some examples are shown to illustrate the process of the resynchronization. Base on above mentioned the paper proposed a suggestion for optimizing the generator protection and control scheme to realizing the resynchronization.
