Abstract:
In order to solve the problems of inaccurate measurement of transmission line impedance parameters , a measurement method of transmission line impedance parameters based on big data is proposed.The parameter model of the traditional untransposed wire is analyzed , and the relationship of the physical quantities in the π-type equivalent network is explained.The predicted physical quantities of transmission line parameters and the estimated model are analyzed.The power flow calculation model of the three-phase line is analyzed , and the big data transmission line parameter prediction method using SCADA as the measurement system is explained.A quasi-steady state estimation method is proposed for load fluctuations.Finally , a simulation analysis is carried out using a simulation model, which demonstrates the effectiveness of the method proposed in this paper.
