摘要/Abstract

摘要：

在低频交流输电系统中,海上风电场和陆上交流系统之间因频率解耦和信号传输延迟,导致海上风电场无法及时响应陆上电网频率变化.为此,结合系统惯量分析,提出一种提升海上风电场主动频率支撑能力的控制策略.在频率信号传递方面,基于模块化多电平矩阵变换器(M³C)低频侧构网V/f控制策略,结合系统惯量设计附加频率下垂控制器,建立M³C网侧与低频侧的频率耦合关系,从而实现两侧频率信息的实时传递.在频率支撑方面,当系统发生扰动产生频率偏差时,海上风电机组通过附加下垂控制可调整功率指令值,进而为系统提供频率支撑.最后,在MATLAB/Simulink平台中,通过负荷变化和三相交流短路故障的仿真,验证了所提协同控制策略的有效性.

Abstract:

In low frequency alternating current (AC) transmission systems, offshore wind farm is unable to respond to changes in onshore grid frequency in a timely manner due to frequency decoupling and signal transmission delays between the offshore wind power system and the onshore AC system. To address this issue, a control strategy is proposed to improve the active frequency support capability of offshore wind farms by combining the system inertia. In terms of frequency signaling, an additional frequency sag controller is designed based on the V/f control strategy of the low-frequency-side structure network of modular multilevel matrix converter (M³C), combining with the system inertia. The frequency coupling link between the M³C net side and the low-frequency side is established to realize the real-time transmission of frequency information between the two sides. In terms of frequency support, when the system is disturbed to generate frequency deviation, the offshore wind turbine can adjust the power command value through additional droop control, thereby providing frequency support for the system. Finally, the effectiveness of the proposed coordinated control strategy is verified in MATLAB/Simulink by the simulation of load change and three-phase AC short circuit fault.

Key words: low frequency alternating current (LFAC) transmission system, frequency coupling, collaborative control strategy, frequency support
