摘要

本文提出了一种利用基于模态特征值调整（MER）的方法提取单模反馈信号的新方法。选择包含相关模态相关信息的单模反馈信号，忽略最小参与状态。这些信号被用作同步发电机（SGs）的高压直流（HVDC）联络线变换器和励磁器的补充输入，旨在增强振荡的区域间模式（IAMs）的阻尼。该方法通过印度东部地区（ER） 25台机、105总线截断电力系统进行了全面的评估和验证，并通过实时硬件在环（HIL）仿真进一步验证。

A Novel Modal Eigenvalue Realignment-Based Design of Wide-Area Damping Controller for Inter-Area Oscillations in Modern Power System

This letter proposes a novel method to extract single-mode feedback signals using a modal eigenvalue realignment (MER) based approach. The single-mode feedback signals those contain information pertinent to the concerned modes are selected, while states with minimal participation are disregarded. These signals are utilized as supplementary inputs to high-voltage direct current (HVDC) tie-line converter and exciters of synchronous generators (SGs) aiming to enhance the damping of inter-area modes (IAMs) of oscillation. The proposed method is thoroughly evaluated and validated using a 25-machine, 105-bus Eastern Regional (ER) truncated power system of India, and further verified through real-time hardware-in-the-loop (HIL) simulation.

期刊介绍： The scope of IEEE Transactions on Power Systems covers the education, analysis, operation, planning, and economics of electric generation, transmission, and distribution systems for general industrial, commercial, public, and domestic consumption, including the interaction with multi-energy carriers. The focus of this transactions is the power system from a systems viewpoint instead of components of the system. It has five (5) key areas within its scope with several technical topics within each area. These areas are: (1) Power Engineering Education, (2) Power System Analysis, Computing, and Economics, (3) Power System Dynamic Performance, (4) Power System Operations, and (5) Power System Planning and Implementation.
