【摘要】：為了合理選取適用于江蘇如東大規(guī)模集群式風(fēng)電工程的并網(wǎng)方案,首先分析比較了基于交流輸電方式和柔性直流輸電方式的海上風(fēng)電并網(wǎng)技術(shù)的優(yōu)缺點(diǎn)。然后給出了基于柔性直流輸電方式的海上風(fēng)電場并網(wǎng)的幾種典型拓?fù)?并對各種并網(wǎng)拓?fù)涞膬?yōu)缺點(diǎn)進(jìn)行分析。在此基礎(chǔ)上,對規(guī)劃建設(shè)中的江蘇如東大規(guī)模集群式風(fēng)電工程的并網(wǎng)拓?fù)湔归_研究,提出了全交流、交流和直流點(diǎn)對點(diǎn)、交流和直流環(huán)形、交流和直流星形4種典型的并網(wǎng)方案。最后,選擇經(jīng)濟(jì)性比較范圍,采用現(xiàn)金流折現(xiàn)模型,從設(shè)備成本、維護(hù)成本和損耗費(fèi)用3個(gè)方面計(jì)算了所提方案的總成本,進(jìn)行了經(jīng)濟(jì)性比較和分析。結(jié)果表明,該工程采用全交流方式時(shí)經(jīng)濟(jì)性最佳,其次分別為交流和直流點(diǎn)對點(diǎn)混合并網(wǎng)方式、交流和直流星形混合并網(wǎng)方式、交流和直流環(huán)形并網(wǎng)方式。
[Abstract]:In order to reasonably select the grid-connected scheme suitable for the large-scale cluster wind power project in Rudong Jiangsu Province the advantages and disadvantages of offshore wind power grid connection technology based on AC transmission mode and flexible direct current transmission mode are analyzed and compared. Then several typical topology of offshore wind farm based on flexible direct current transmission are given, and the advantages and disadvantages of each topology are analyzed. On this basis, the topology of grid connection of large scale cluster wind power project in Rudong, Jiangsu Province, is studied, and full AC, AC and DC point-to-point, AC and DC ring are proposed. Ac and DC star four typical grid-connected schemes. Finally, the total cost of the proposed scheme is calculated from the three aspects of equipment cost, maintenance cost and loss cost by using the cash flow discount model, and the economic comparison and analysis are carried out. The results show that the economy of the project is the best when adopting full AC mode, followed by AC and DC point-to-point hybrid grid-connected mode, AC and DC star hybrid grid-connected mode, AC and DC ring grid-connected mode.
