发电机组涉网保护与限制配合的自动校核

Automatic check of coordination between grid-related unit protection and limiter

在研究涉网保护动作特性的基础上,针对实际电厂中涉网保护定值参数整定不合理以及保护与限制之间配合不合理的问题,探讨了实际应用中涉网保护与限制之间的配合原则,提出了大规模电网涉网保护与限制配合关系自动校核的方法。基于PSD-FDS,采用分层模块化思想,开发了涉网保护与限制自动校核软件,该软件实现了大规模电网中涉网保护与限制之间配合关系的自动校核。

The operating characteristics of grid-related unit protection are studied,the improper setting of its parameters and the improper coordination between grid-related unit protection and limiter in actual power plants revealed,the relevant coordination principles discussed and the method to automatically check the coordination relationship between them proposed for the large-scale power grid. The hierarchical modularization concept is adopted in the development of related automatic checking software based on PSD-FDS.
