基于扩展潮流的输电断面最大传输能力
The total transfer capability of cross-section of transmission line based on expanded power flow
摘要
Abstract
A novel idea based on expended power flow model is proposed for calculating the total transfer capability (TTC) of system transmission cross-section. In expended power flow model, the influence of speed governor, excitation system and other dynamic devices on system transmission capacity is considered, thus breaking the assumption of constant terminal voltage of generators in the traditional TTC calulation, which makes the results more realistic. In this paper, a mathematical model based on expended power flow is established for the calculation of TTC. The model is solved by linear programming method. During the process of solving, the overall step adjustment based on trust region method and the single step adjustment based on curvature are combined. At last, the feasibility and effectiveness of the model and the method are testified by New England 39-nodes system.This work is supported by National Natural Science Foundation of China (NSFC) (No. 5037702 land No. 50677036).关键词
