基于慢同调的自适应主动解列控制(三):实用方案设计

Adaptive Islanding Control Based on Slow Coherency—Part Ⅲ:Design of the Practical Scheme

介绍一种利用广域测量系统(wide area measurement system,WAMS)量测信号,基于慢同调理论的自适应主动解列控制实用化技术方案,包括基于量测类噪声信号进行系统慢同调区域划分的流程;基于"角半径"和量测暂态轨迹信号的分层分区暂态稳定判别和失稳模式识别方法;解列控制策略以及孤岛功率辅助控制策略的生成方法。此方案不依赖于系统数学模型,是一种无模型化的方案。在IEEE-118节点测试系统上验证了所提方案的有效性。

This Paper proposed a practical scheme for the adaptive islanding control based on slow coherency theory utilizing the measured signals by WAMS. The scheme includes： slow coherency based area partition based on measured ambient data; transient stability discrimination and the instability pattern identification in hieratical way based on the measured transient trajectory curves; generation of the islanding strategy and the auxiliary control strategy for the formed islands. The scheme does not depend on the mathematical model of the system, i.e., it is a model-free scheme. The scheme was verified on the IEEE-118 buses test system.
