- Discussion of several analytical approaches and tools about subsynchronous resonance
几种次同步振荡分析方法和工具的阐述 - This thesis focuses on analysis and control of low - frequency electromechanical oscillations in power systems based on prony ' s method . the main work is as follows : 1
本文以基于prony法的电力系统低频振荡分析与控制为研究内容，主要做了以下工作： 1 - Applying normal form method , conventional eigenvalue calculation and prony analysis , small signal stability and time domain simulation can be combined efficiently . the proposed method can get nonlinear information which never obtained by past techniques , so it shows a new way for analyze oscillation problems in interconnected power systems
通过正规形方法、小信号稳定特征值计算技术、时域仿真、 prony分析的有机结合，达到小扰动和大扰动后低频振荡稳定性分析的统一，为互联系统低频振荡分析开辟了新的思路。 - Digital simulations reveal many valuable characteristics of the power system low frequency oscillation . the limit of conventional analysis and the appearance of new technique such as wams together with the advance of the nonlinear theory , require a new method for oscillation research of power grid , which can combine small and large disturbances analysis effectively
论文指出，由于传统小信号稳定分析方法的局限性，及动态监测设备和非线性理论等新技术与理论的迅速发展，有必要研究新的振荡分析方法，以更加有效地揭示互联系统小扰动、大扰动后的振荡机理，并研究相应的控制策略。 - All these changes , which are of importance to subsynchronous oscillation analysis , cannot be described with the quasi steady state ( qss ) model any more . therefore , the deficiency of qss - model - based eigenvalue method is pointed out and a novel method named complex torque coefficient - test signal method is adopted to analyze the subsynchronous oscillation caused by hvdc or facts devices
基于此，指出了采用准稳态模型进行hvdc系统次同步振荡分析的局限性，并引入了分析hvdc或含有facts装置的系统次同步振荡问题的方法：复转矩系数- - - -测试信号法。
