Research on Transmission Line Planning Method Considering Power Output Behavior
To solve the problems of large network loss power and poor planning effect that exist in traditional transmission line planning methods,the transmission line planning method considering power output behavior is designed.Firstly,the power output behavior constraints are established through nonlinear equation fitting.Then,the quantitative calculation of power output behavior is completed by calculating the grid current volume.Finally,according to the numerical level of the power output behavior,the numerical level of the static voltage sensitivity index is determined,and the modified expression of the planning coefficient is united to realize the design of the transmission line planning method.The results of comparative tests show that the proposed method can accurately calculate the power output behavior in 35 kV and 110 kV grid organizations,and is able to control the network loss power under the established numerical standards.The application of this method to plan power network transmission lines can effectively control the amount of network loss,realize the rational planning of the application of the power grid.The method can meet the practical application requirements.
