摘要
电网同期存在差频并网和同频并网操作两种形式，针对这两种并网形式不同的自动化解决方案，分析了现行同期装置在解决该问题方面存在的不足，提出了改进措施。
Synchronization of power network can be performed by either differential - frequency paralleling or identical - frequency paralleling. For different automation solutions of the two types of paralleling, this paper analyzes current synchronizing devices for their deficiencies in this regard, and puts forward improvement measures.
