【摘要】：為滿足遠(yuǎn)距離清潔電力輸送及東部負(fù)荷發(fā)展的需要,特高壓技術(shù)正在我國得到大量應(yīng)用。多回直流集中饋入受端負(fù)荷中心將是未來我國電網(wǎng)發(fā)展所面臨的重要問題,而功率/電壓穩(wěn)定就是其中重點(diǎn)研究課題之一。以往最大傳輸功率研究成果主要關(guān)注單回直流最大傳輸功率以及多饋入系統(tǒng)情形下某個(gè)直流的最大傳輸功率。但是,對于區(qū)域合計(jì)所能實(shí)現(xiàn)的最大直流傳輸功率,還未見有報(bào)道。該文對以往多饋入直流輸電系統(tǒng)靜態(tài)功率模型進(jìn)行了拓展與深化,建立廣義的多饋入直流輸電系統(tǒng)靜態(tài)功率模型,揭示區(qū)域最大傳輸功率的含義,采用梯度法求解區(qū)域所能實(shí)現(xiàn)的最大傳輸功率,并通過矩陣變換化簡,在最大傳輸功率與傳統(tǒng)臨界多饋入短路比之間建立聯(lián)系。該文的研究成果為以往多饋入相關(guān)均衡性概念與結(jié)論提供了理論支持,對某一區(qū)域多饋入直流最大傳輸功率的分析及調(diào)整策略給出了新的方法,同時(shí)對規(guī)劃階段優(yōu)化直流布局起到指導(dǎo)作用。
[Abstract]:In order to meet the needs of long-distance clean power transmission and eastern load development, ultra-high voltage (UHV) technology is being widely used in China. The power / voltage stability is one of the most important problems in the future development of China's power grid, in which the multi-circuit DC centralized feed into the receiving load center will be an important problem in the future. Previous research on maximum transmission power mainly focused on the maximum transmission power of single circuit DC and the maximum transmission power of a DC in the case of multi-feed system. However, it has not been reported that the maximum DC transmission power can be achieved by the total area. This paper extends and deepens the static power model of multi-feed HVDC system, establishes a generalized static power model of multi-feed HVDC system, and reveals the meaning of the maximum transmission power in the region. The gradient method is used to solve the maximum transmission power which can be realized in the region, and the relation between the maximum transmission power and the traditional critical multi-feed short circuit ratio is established by matrix transformation. The research results of this paper provide theoretical support for the concept and conclusion of multi-feed correlation equilibrium, and give a new method to analyze and adjust the maximum transmission power of multi-feed DC in a certain region. At the same time, it plays a guiding role in the optimization of DC layout in the planning phase.
