摘要/Abstract

摘要： 随着风能利用规模的发展，风电渗透率不断提高，局部地区已达到50%以上.由于风电变流器的隔离作用，风电机组的转子运动和系统频率解耦，使得风电机组对于电力系统的惯量几乎没有贡献，降低了系统等效惯量，严重影响系统的频率稳定性.大型风电机组的惯量控制技术旨在利用机组转子动能赋予风电机组主动惯量响应和抑制电网频率跌落的能力，本文综述目前大型风电机组实现惯量控制的主要技术路线，从稳定性分析、控制系统优化、性能分析与评估等方面，介绍惯量控制在双馈风电机组以及全功率风电机组的研究与工程现状，并展望亟待解决的问题与技术需求.

Abstract: With the rapid development of wind power, wind power penetration is continually increasing and has reached over 50% in certain areas. However, rotor motions of wind turbines are decoupled from system frequency owing to the isolation effects of wind power converters, which makes wind turbines provide no inertia support for power system，lowers system equivalent inertia and even has serious influences on system frequency stability. Inertia control technology of large scale wind turbines aims to enable active inertia response and frequency damping ability for wind turbines by using kinetic energy of wind turbine rotors. This paper summarizes the main technical routes of inertia control in large scale wind turbine system, introduces engineering and research status of inertia control in DFIG and PMSM wind turbine system concerning stability analysis, improvement of control system, performance analysis and evaluation, and finally looks ahead to the urgent problems and technical requirements which remain to be solved.

Key words: wind power penetration, large scale wind turbine system, inertia control, frequency response
