【摘要】：隨著海上風(fēng)場的大規(guī)�；l(fā)展,如何經(jīng)濟有效地將分散在海上各處風(fēng)場所發(fā)電能匯聚并傳輸至岸上成為一個亟待解決的問題。對比傳統(tǒng)海上風(fēng)電場的交流匯聚、直流傳輸,全直流風(fēng)場以其體積小、容量大、效率高等優(yōu)勢,引起學(xué)界廣泛關(guān)注。作為全直流風(fēng)場中的關(guān)鍵設(shè)備,多端口直流變電站起著重要的匯聚與傳輸風(fēng)能的作用。該文基于模塊化多電平結(jié)構(gòu),針對可能應(yīng)用于全直流風(fēng)場中的幾種多端口直流變電站拓撲,從變比、故障隔離、容量等幾方面展開詳細分析與對比,并就在不同場合下應(yīng)選擇何種拓撲作出建議。并提出應(yīng)用于海上直流風(fēng)場中的多端口直流變電站最優(yōu)拓撲。
[Abstract]:With the large-scale development of offshore wind field, it is an urgent problem to solve the problem of how to gather and transmit the power generation energy scattered around the sea wind field to shore economically and effectively. Compared with the conventional offshore wind farms, such as AC converging, DC transmission, full DC wind field has attracted wide attention due to its advantages of small volume, large capacity, high efficiency and so on. As the key equipment in the whole DC wind field, multi-port DC substation plays an important role in converging and transmitting wind energy. Based on the modularized multilevel structure, this paper presents a detailed analysis and comparison of several multi-port DC substation topologies that may be used in the full DC wind field from the aspects of variable ratio, fault isolation, capacity, etc. Suggestions are made on what topology should be chosen in different situations. The optimal topology of multi-port DC substation applied to offshore DC wind field is presented.
