摘要
随着风电机组对传统同步机组的替代,电力系统的风力发电渗透率不断提高,使得系统的总惯量降低、频率稳定性被削弱.风电机组的转子动能控制技术可以实现机组转子旋转动能和电能的灵活转化,以提高系统频率支撑能力.为此,介绍并分析了包括虚拟惯性控制、下垂控制和综合惯性控制在内的传统风电机组转子动能控制策略,并对转子动能控制技术的发展方向做出展望.
Abstract
The emerge of wind turbine generators(WTGs)which gradually replace conventional synchronous generators,results in rising permeability of wind power generation in power system,but also lowered inertia and weakened frequency stability.The rotor kinetic energy control technology for wind turbines can realize flexible conversion between rotors'rota-tional kinetic energy and electric power,facilitate improvement of frequency stability of the system.This paper introduces and analyzes the conventional rotor kinetic energy control strategies for WTGs,including virtual inertia control,droop control and integrated inertia control,and gives prospective outlook on future development of this technology.
