Abstract: Introduction was made to the power transmission system electromagnetism transient model of offshore wind farm adopting long-distance high-voltage submarine cable. The simulation software EMTP/EMTPE was adopted to analyze the frequency overvoltage of high-voltage submarine cable and overhead line. On the basis of this, the capacity of high-voltage shunt reactors and lowvoltage reactive compensators was studied to obtain the reactive compensation configuration plan of offshore wind farm. Taking certain coastal offshore wind farm for example, this paper carried out comprehensive analysis and calculation to the frequency overvoltage and reactive power compensation, which verifies the feasibility of the proposed plan.
Key words: offshore wind farm; submarine cable; mixed line; frequency over-voltage; reactive power compensation
