Reactive Power Configuration Influence on Output Cable Loss of Offshore Wind Farm

doi:10.3969/j.issn.1000-7229.2015.06.019

Abstract

Abstract:

Based on the transmission system model and submarine cable parameters of offshore wind farm, the reactive power compensation configuration mode of offshore wind farm and the calculation method of submarine cable loss were analyzed. A simplified model of offshore wind power transmission system was established; and the output cable loss under two different compensation schemes: both ends compensation and single-end compensation on land, were calculated for offshore wind farms with different scales and transmission distances; the power loss-wind farm output curves of submarine cable were obtained. Both ends compensation will have a lower cable power loss when the wind farm is in the low output level or with long distance transmission, while single-end compensation will have a little lower cable power loss when the wind farm is in the high output level or with short distance transmission.

Key words: submarine cable, offshore wind power, reactive power compensation, loss
