同步发电机的过励磁限制对电力系统的电压稳定起着重要作用。实现过励磁能力的最大利用需要发电机控制和保护之间的充分协调。本文提供了同步发电机过励磁限制器（OEL）、励磁过流保护和自动电压调节器（AVR）之间协调的示例。然后使用电磁瞬态程序针对感兴趣的实际场景进行模型模拟来验证所实现的协调。提出了对 ST1A 型励磁机模型的建议修改，以代表 OEL 功能的完整功能。
The overexcitation limit of synchronous generator plays an important role in the voltage stability of power systems. Achieving maximum use of the overexcitation capability requires adequate coordination between generator control and protection. This paper provides an example of coordination between overexcitation limiter (OEL), field overcurrent protection and automatic voltage regulator (AVR) for a synchronous generator. The coordination achieved is then verified by a model simulation using an electromagnetic transient program for practical scenarios of interest. Suggested modifications to the ST1A type exciter model are presented to represent the complete functionality of the OEL function.
