摘要: 云南与南方电网主网异步联网后,云南电网频率稳定风险增大,直流频率限制控制(FLC)可实现直流功率大范围快速调节,是电网频率稳定控制的重要措施。基于云南电网实际运行情况,全面分析了直流FLC应用于省级区域电网频率控制的相关问题,包括FLC功能配置原则、调节范围及死区设置、调节量需求及直流过负荷能力等,并结合实际案例分析了FLC动作特性,提出现场实施方案。直流FLC在云南异步联网应用的成功经验,可为后续工程应用提供借鉴指导作用。

Abstract: Asynchronous interconnection between Yunnan province power grid and China southern main grid increases system frequency stability risk. The Frequency limit control (FLC) of HVDC realizes quick and large range power modulation, and is very helpful to maintain system frequency stability. Based on actual operating conditions in Yunnan, some problems of FLC application in provincial area power grid are analyzed comprehensively, including principle of function configuration, regulation range, dead band configuration, HVDC overload. FLC dynamic response characteristics are analyzed with case study. A field implementation plan is also proposed. The successful experience of FLC application in Yunnan provincial grid provides valuable reference and guidance for follow-up project.

Key words: HVDC, Frequency limit control, Asynchronously Interconnected, area power grid
