摘要: 针对海上油田群电网接入海上风电引发的频率稳定问题,提出了分散式风储一体化系统(distributed wind-storage integrated system,DWSIS)的解决方案。首先,基于某实际油田群电网,构建了DWSIS及其接入电网的模型;然后,提出了DWSIS改善电网频率稳定性的原理及分析方法;最后,通过各典型故障下的电磁暂态仿真,验证了DWSIS的有效性和实用性。所提出的解决方案有望提升高风电渗透率下海上油田群电网的频率稳定性,进一步推动海上平台生产的低碳化发展。

Abstract: Aiming at the frequency stability problem of the offshore oilfield power systems (OOPSs) caused by the integration of offshore wind power, this paper proposes a solution based on the distributed wind-storage integrated system (DWSIS). Firstly, based on a real OOPS, the model of DWSIS is constructed as well as the grid it integrated into. Then, the principle and analysis method are proposed of DWSIS to improve the frequency stability of the grid. Finally, the effectiveness of the DWSIS is verified via electromagnetic transient simulation. The DWSIS proposed can be expected to improve the frequency stability of the OOPSs with high penetration of wind power and promote the low-carbon development of offshore platform production.
