【摘要】：為了結(jié)合海底電纜壽命周期特點、制定適用于近海風(fēng)電場高壓海底電纜的選型標準,以海纜傳輸容量大于風(fēng)電場設(shè)計向外傳輸容量為約束條件,構(gòu)建了包括購置、敷設(shè)、損耗、故障損失、運行維護以及回收凈投資成本的海纜全壽命周期成本(LCC)模型,并以LCC等額年值最小作為選型標準。以國內(nèi)某海上風(fēng)電場海底電纜選型為案例進行計算分析。結(jié)果表明,購置、損耗、故障損失成本與自身LCC占比較重,最高分別達到26.4%、30.8%、62.0%;所有方案前期投資與自身LCC占比≤40%。當電壓等級相同時,單芯海纜方案損耗成本至少比三芯海纜方案高出4.68×103萬元;而當線芯數(shù)相同時,高電壓等級故障損失成本至少比低電壓等級海纜方案高出8.8×103萬元;2回110 k V 3×500 mm2高壓XLPE絕緣鋼絲鎧裝海纜方案LCC等額年值(3.08×103萬元/a)最小,該方案最優(yōu)。
[Abstract]:In order to combine the characteristics of submarine cable life cycle, the selection standard of high voltage submarine cable suitable for offshore wind farm is established. Taking the transmission capacity of submarine cable larger than the design outward transmission capacity of wind farm as the constraint condition, the paper constructs the design including purchase, laying, loss, etc. The (LCC) model of the whole life cycle cost of submarine cable with fault loss, operation maintenance and net investment cost recovery is used as the model selection standard. The minimum annual equivalent value of LCC is taken as the model selection standard. Taking the submarine cable selection of a domestic offshore wind farm as a case, the calculation and analysis are carried out. The results show that the cost of purchase, loss and fault loss is heavy with their own LCC, and the highest is 26.4and 30.880 / 62.0, respectively, and the proportion of pre-investment and LCC of all schemes is 鈮，
