摘　　要：通过对含多个失步断面彼此相邻的复杂电网研究发现,如若整定不当,基于就地量的传统解列装置存在无序解列的潜在风险。文中分析了传统协调配合方法的欠缺,指出传统方法难以兼顾解列装置的快速性和选择性,而利用系统通信的协调配合方法,需要更多的系统信息的配合,依赖于快速可靠的系统通信。在对传统判据和协调配合方法研究的基础上,提出了解列装置定值两级配置方案,实现传统基于就地量失步解列装置可靠性、选择性和快速性的协调统一,有效解决了电网内部有多个失步断面彼此相邻或电气距离较近时,失步解列装置如何协调配置的问题。According to the simulation analysis on the complex power system with some out-of-step interface borders between different areas, it is found that the risk of misoperation of multi-interfaces separation is existent. The reason lies in the uncoordinated islanding scheme of out-of-step devices. The traditional coordinating scheme is difficult to compromise between selectivity and celerity simultaneously. Furthermore, the coordinating methods between different out-of-step devices by communication also need more system information comes from a far place, which highly depends on the reliability and rapidness of communication. A two-level setting scheme for out-of-step device is proposed. With this new setting scheme, out-of-step device can be provided with credibility, selectivity and celerity simultaneously, and it can be used to deal with the problem of configuring out-of-step device in a complex power grid with multi-interface borders.
