摘要: 针对具有高阻抗阶梯型输电通道电网在使用传统失步解列装置时难以取得良好解列效果的问题,提出基于慢同调理伦的高阻梯级通道解列策略。首先,基于慢同调理论对节点电气连接分类,据此分析高阻梯级通道解列特点,并指出该类通道存在边缘节点易使解列装置动作后同调划分混乱的问题。其次,针对高阻梯级通道链式阻抗结构,结合自然断点法提出一种适用于高阻梯级通道的慢同调解列策略。最后,采用IEEE 39节点标准算例系统与我国西部某省级电网对所提解列策略进行仿真验证。仿真结果表明,所提慢同调解列策略能够有效搜索最优解列断面,对含高阻梯级通道形式电网具有良好适应性与有效性。

Abstract: Large-scale high-impedance cascaded transmission corridors have been built in some regions of China, where traditional out-of-step islanding devices often underperform.This paper proposes ahigh-impedance cascaded corridorsislanding strategy based on slow coherency theory. firstly, based on slow coherency theory, the electrical connections of nodes are classified. Characteristics of high resistance cascade channel splitting are analyzed accordingly, and indicate that this type of channel has the problem of confusion in islanding division after the splitting device is activated due to edge nodes. Secondly, for the chain impedance structure of high impedance cascade channels, a slow coherency and islanding strategy suitable for high impedance cascade channels is proposed by combining natural breaking point method.finally, the IEEE 39 node standard calculation system is used to simulate and verify the proposed strategy with a provincial power grid in western China.Simulation results show that the proposed strategy can effectively search for the optimal solution section, and has good adaptability and effectiveness for power grids with high resistance cascade channels.

Key words: slow coherency theory, high-impedance cascaded corridors, natural breaking point method, islanding strategy
