摘要
提出了一种新的利用Agent实现的电网后备保护系统。它优于由传统第Ⅲ段保护构成的后_ 备保护系统,动作更快而且更具有选择性,其自检和纠错能力能减少保护的不正确动作。阐述了Agent的基本思想,分析了Agent保护通信特点,提出了基于Agent的电网后备保护系统原理结构、算法和IP通信实现,利用电力和通信系统同步仿真平台EPOCHS在一简单电力系统上对所提出的保护系统进行了仿真实现,证明了所提出的方法的有效性。
This paper proposes a novel backup protection system for the electric power grid that makes use of Agents. Faster and allowing for more selective protection, the new relays are significantly better than their traditional counterparts. Maloperation is reduced by the Agent＇s self-checking and self-correcting ability. This paper presents the basic conception of Agents and analyzes the communication networks for relay Agents. The principle structure, protection strategies and IP-based communication methods of the Agent-based backup protection are proposed. Simulations run in a typical power system using the EPOCHS platform illustrate the effectiveness of the proposed method.
