基于慢同调的自适应主动解列控制(二):实用慢同调区域划分方法

Adaptive Islanding Control Based on Slow Coherency—Part Ⅱ: Practical Area Partition Method

首先引入广义特征分析技术,针对含负荷节点的电力系统设计慢同调分群算法。在对发电机和负荷进行慢同调分群的基础上,提出考虑系统拓扑信息和功率平衡约束的电力系统慢同调区域划分方法。在IEEE-118节点系统上进行了算例测试,测试结果表明,所提方法的慢同调区域划分结果是合理的,能够满足自适应主动解列控制实用化的需要。

This paper firstly designed a slow coherency based grouping method which can deals with the load buses in system by introducing the generalized eigenvalue analysis technique. Based on the grouping result of generator and load buses, a slow coherency based area partition method was proposed considering the topology information and power balance constraint. The methods proposed was tested on the IEEE-118 system, the result of slow coherency area partition is reasonable and can meet the needs of the practical adaptive islanding control.
