摘要

失步振荡是电力系统中一种破坏性很强的物理现象,可直接导致大停电,并伴随着严重的社会经济影响。失步分裂控制是保护系统免受失步振荡重大冲击的一种不可或缺的手段。经过多年的发展,它已经取得了一定的研究成果。现有的方法能否满足步外分裂的要求?还需要做哪些改进?在此背景下,我们撰写了这篇综述。它梳理了台阶外分裂控制技术的发展脉络,分析了不同方法的技术路线和特点。文章指出,快速与优化之间的矛盾是最大的技术问题,无论是基于局部测量的传统步外分裂保护,还是基于广域信息的步外分裂保护,都存在这一问题。报告进一步指出,可以将这两种保护方式的优势与台阶外中心独特的物理特性相结合,形成更具优势的分路策略。此外,面对近年来可再生能源大规模接入电网的事实,本综述还分析了其带来的挑战,并提出了一些相应的建议。希望能为后续的研究工作提供一些指导。

Review of the development of power system out-of-step splitting control and some thoughts on the impact of large-scale access of renewable energy

Out-of-step oscillation is a very destructive physical phenomenon in power system, which could directly cause big blackout accompanied by serious sociology-economic impacts. Out-of-step splitting control is an indispensable means, which could protect the system from major shocks of out-of-step oscillation. After years of development, it has achieved certain amount of research results. Have the existing methods been able to meet the requirements of out-of-step splitting? What improvements are needed? Under this background, this review is written. It combs the development of out-of-step splitting control technologies and analyzes the technical routes and characteristics of different methods. It points out the contradiction between rapidity and optimality is the biggest technical problem, existing in both the traditional local measurement based out-of-step splitting protection and the wide-area information based out-of-step splitting protection. It further points out that the advantages of the two types of protections can be combined with the unique physical characteristics of the out-of-step center to form a more advantageous splitting strategy. Besides, facing the fact of large-scale renewable energy access to power grid in recent years, this review also analyzes the challenges brought by it and provides some corresponding suggestions. It is hoped to provide some guidance for the subsequent research work.
