A Field Mathematical Model of a Turbine Generator Operating under No-Load Conditions Constructed in Phase Coordinates

摘要

A field mathematical model of a turbine generator in phase coordinates is considered. The model is constructed using the differential equations that describe the vector potential of a quasi-stationary electromagnetic field. The mathematical model enables the integral characteristics (currents and voltages) and also the spatial and time distributions of the main vectors of the electromagnetic field to be calculated simultaneously over the entire cross-section of a turbine generator operating under no-load conditions at a specified voltage applied to the field winding. The differential equations are quantized in space and in time using the finite difference method and the implicit method, respectively. Results of computer simulations are presented.
