【摘要】：针对利用统一潮流控制器(UPFC)的潮流控制能力来改善输电断面潮流分布、解决关键输电线路过载问题的应用场景,基于电网络理论推导了UPFC串联侧装置所需安装容量与关键输电线路潮流转移需求、UPFC安装位置、网架结构参数之间的关系,提出了UPFC串联侧装置安装容量的计算方法。在此基础上,分析了影响UPFC装置安装容量的主要因素,并针对两种典型的网架结构,研究了转移单位潮流所需的UPFC串联侧装置安装容量受UPFC安装位置、网架结构参数的影响情况。进一步,提出了一套简单实用的UPFC安装位置和容量的优化方法。案例分析结果验证了所提出的UPFC串联侧装置安装容量计算方法和关键影响因素分析的有效性,同时验证了所提出的UPFC安装位置和容量优化方法的可行性。
[Abstract]:Aiming at improving the power flow distribution of transmission section by using the power flow control ability of UPFC (Unified Power flow Controller) and solving the overload problem of key transmission lines, Based on the theory of electrical network, the relationship between the installation capacity of UPFC series side device and the power flow transfer demand of key transmission line and the structure parameters of UPFC is deduced, and the calculation method of installation capacity of UPFC series side device is put forward. On this basis, the main factors affecting the installation capacity of UPFC device are analyzed, and for two typical grid structures, the installation position of UPFC series-side device required to transfer unit power flow by UPFC is studied. The influence of the structure parameters of the grid. Furthermore, a simple and practical method for optimizing the location and capacity of UPFC installation is proposed. The results of the case study verify the effectiveness of the proposed method for calculating the installation capacity of UPFC series side devices and the analysis of key influencing factors. At the same time, the feasibility of the proposed UPFC installation location and capacity optimization method is verified.
