    摘 要:由于長距離海底電纜的充電功率大量盈余,無法實現(xiàn)無功就地平衡,同時海纜過電壓及沿線電流需滿足海上風電接入相關標準,從海纜沿線的過電壓及電流出發(fā),基于海上風電接入相關標準,制定海上風電無功補償方案配置流程。以實際工程為例,基于 PSCAD 和 PSS/E 軟件搭建海上風電場交流送出仿真模型,研究無功補償配置方案,為海上風電交流送出工程的無功補償配置方案提供了理論支撐,
提升了工程經(jīng)濟性。

    Abstract: The large surplus of charge power from long-distance submarine cables is impossible to achieve reactive power local balance,and the submarine cable overvoltage and current along them have to meet the relevant standards of offshore wind power access. Therefore,the paper starts from the overvoltage and current of submarine cables to make the configuration process of offshore wind power reactive power compensation scheme based on the relevant standards of offshore wind power access. The paper, taking a practical project as an example,designs a reactive power compensation configuration scheme based on the simulation model of offshore wind farm AC transmission built in PSCAD and PSS/E. It provides theoretical support for the reactive power compensation configuration scheme of offshore wind power AC transmission project and improves the engineering economy.
    Key words: offshore wind power; AC transmission; reactive power compensation; electromagnetic transient; electromechanical transient
