Abstract

This paper introduces a virtual consensus-based wide area differential protection method through cooperative control concepts and graph theory. Using multi-agent systems eliminates the need for a direct telecommunication connection between the protective relays to implement the proposed differential protection. In addition, applying telecommunication subgraphs facilitates the establishment of numerous differential protection areas. Collaboration between protected areas is facilitated by common agents, establishing a wide-area cooperative protection network. The capability of the network operator to define various protection areas and the collaboration between these areas ensure the versatility of the proposed method for various protection purposes. The present paper primarily represents the application of the proposed protection system as a wide-area supervisor protection for distance relays. Performance evaluations on an IEEE 39-bus test system illustrate the method's effectiveness in various scenarios. The results show enhanced power system stability and resilience, particularly when traditional methods struggle to detect power swings with high impedance variation rates.

基于虚拟共识的新型广域差分保护
本文通过合作控制概念和图论介绍了一种基于虚拟共识的广域差动保护方法。通过使用多代理系统,无需在保护继电器之间建立直接的电信连接,即可实现所提出的差动保护。此外,应用远程通信子图有助于建立众多的差动保护区域。保护区域之间的协作可通过共同代理实现,从而建立起一个广域合作保护网络。网络运营商定义各种保护区域的能力以及这些区域之间的协作确保了所建议的方法在各种保护目的中的通用性。本文主要介绍了建议的保护系统作为距离继电器的广域监督保护的应用。在 IEEE 39 总线测试系统上进行的性能评估说明了该方法在各种情况下的有效性。结果表明,该方法增强了电力系统的稳定性和恢复能力,尤其是当传统方法难以检测到阻抗变化率较高的电力波动时。

期刊介绍: IET Generation, Transmission & Distribution is intended as a forum for the publication and discussion of current practice and future developments in electric power generation, transmission and distribution. Practical papers in which examples of good present practice can be described and disseminated are particularly sought. Papers of high technical merit relying on mathematical arguments and computation will be considered, but authors are asked to relegate, as far as possible, the details of analysis to an appendix. The scope of IET Generation, Transmission & Distribution includes the following: Design of transmission and distribution systems Operation and control of power generation Power system management, planning and economics Power system operation, protection and control Power system measurement and modelling Computer applications and computational intelligence in power flexible AC or DC transmission systems Special Issues.
