Modeling of accurate nonlinear shunt reactor is basis of harmonic analysis of 1000 kV AC transmission system. Based on the electromagnetic relations of single-phase shunt reactor and the effect of iron core nonlinearity, a new model of single-phase shunt reactor used for harmonic analysis and computer simulation is presented. It presented shunt reactor by a simple equivalent circuit consisting of...
Against the background of 1000 kV AC Pilot Project from Jindongnan to Jingmen via Nanyang which has been completed in January 2009, based on accurate modeling of the nonlinear equipments such as autotransformer and shunt reactor in 1000 kV system, the harmonic characteristics of 1000 kV system are calculated and analyzed in PSCAD/EMTDC. Simulation results show that for the 1000 kV system, the total...
With the rapidly developing of electrified railways, the adverse effects on the public power grid brought by traction power-supply system have been increasingly taken into account by railway and electricity department. In order to analyze the harmonics influence caused by traction power-supply system, the models based on PSCAD/EMTDC of typical traction power-supply system and public power grid have...
