摘要
共振型低频振荡是电力系统较为常见的一种典型的系统振荡方式,尽早地发现扰动源就能够及时切除故障,这对于系统安全稳定运行至关重要。文中对两种实用的共振型低频振荡溯源方法进行研究,在综述其溯源原理的基础上,总结了它们的特点,并且讨论了在实际应用中可能遇到的一些问题,分析了其实现的可能性。目的是为进一步发展基于广域测量技术的共振型低频振荡溯源打下基础。
Low frequency oscillation of resonance mechanism is a common typical power system oscillation type. It is of utmost importance tbr the seeurity and stability of power system to identify disturbance source and remove it as early as possible. This paper, based on studying the literatures of tracing the source of the low frequency oscillation of resonance mechanism and their theory, summarizes the characteristics of two practical methods, and analyzes the problems and possibility of their application in practice. This study mainly aims at establishing a strong basis for future research on locating the source of the low frequency oscillation of resonance mechanism based on WAMS.
