摘要
综述了发电机组再同步的意义、控制策略和关键技术及其存在的问题。对发电机组再同步过程进行了简单的回顾,对国内外发电机组失步预测方法进行了概述和分析,指出了存在问题和发展方向,介绍了发电机组再同步控制手段(快控汽门和强励/强减励磁)的优点及不足之处,阐述了再同步协调综合控制的必要性。在发电机组再同步控制规律方面,介绍了单机系统的应用现状,并探讨了多机系统控制规律的重点研究课题。
This article gives an overview of the meaning, control scheme, key techniques and existing problems of genset resynchronization, briefs the process of resynchronization, analyzes the asynchronous prediction methods at home and abroad, indicates the developing trend and introduces the merit and deficiency of the resynchronous measurement, and expatiate upon the necessity of integration and coordination control. In the aspect of control rules, this article also gives the actuality of single unit control system, and discusses the key research task in multi-unit power systems.
