Study on Application of HVDC Frequency Limit Control (FLC) in Asynchronously Interconnected Yunnan Grid

doi:10.11930/j.issn.1004-9649.201701069

Abstract

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
