同期装置定值整定分析

Analysis of Setting Value of Synchronizing Device

文章介绍了某电厂同期系统的构成及其工作原理,通过对两起发电机并网时发生进相运行事件的分析,判断出同期装置定值整定与系统一次运行方式不匹配是造成事件的直接原因,给出了同期装置定值整定的正确方法及并网过程中减少无功冲击的建议。

The composition and working principle of the synchronous system of a power plant were introduced.Through the analysis of two events of leading phase operation when the generator was connected to the grid,it was judged that the mismatch between the setting value of the synchronous device and the primary operation mode of the system was the direct cause of the event.The correct method of setting the setting value of the synchronous device and the suggestion of reducing the reactive power impact in the process of connecting to the grid were given.
