摘要
为了横向对比目前主流风电机组虚拟惯量控制的性能与效果,首先形成了评价指标体系,然后基于实时数字仿真器(real-time digital simulator,RTDS)和气动分析软件GH Bladed构建了2 MW双馈风电机组数字镜像系统,进而详细分析了各种惯量控制方式在电网频率阻尼、弱网运行稳定性、电网频率二次跌落和机组载荷影响等方面的优缺点。研究结果表明:不同的虚拟惯量控制方式在频率阻尼方面的效果类似;惯性同步控制(inertial synchronization control,ISynC)以及虚拟同步控制(virtual synchronous generator control,VSG)能显著提高机组弱网稳定运行的能力;此外,虚拟同步控制在降低电网频率二次跌落以及减小塔架疲劳载荷方面效果明显,可为今后的研究提供横向对比的实验支撑。
In order to comprehensively compare the performance and effects among different virtual inertia control methods,a comprehensive evaluation index system is proposed in this paper,and a 2 MW double fed wind turbine generator(WTG)digital mirroring system is designed based on real time digital simulator(RTDS)and pneumatic analysis software Garrad Hassan Bladed(GH Bladed),and then,detailed analysis is carried out among different virtual inertia control schemes in terms of inertia response performance,weak grid operation stability,secondary frequency drop and wind tower load analysis.The research results reveal that different control schemes are similar in inertia response,virtual synchronous generator control(VSG)and inertial synchronization control(ISynC)can improve weak grid operation stability,while VSG strategy is effective in reducing the secondary drop of frequency and fatigue load of wind tower,which can provide experimental supports for future research.
