In this paper, a three-stage generator model is established based on Modelica/Dymola. Start from the mathematical model of the generator, the main generator (MG) and the main exciter (ME) are remodeled by using the Modelica language. Then, the generator control unit (GCU), the pre-exciter (PE) and the rotating rectifier model are built using components in standard library of Dymola. And Dymola is...
This paper presents a proposal for the mathematical modeling and computational analysis of special permanent magnetic excitation six-phase synchronous generators, as required by variable wind farm application. The strategy uses time domain techniques so as to highlight the transient, dynamic and steady state operational conditions. Having completed the representation and the computational implementation...
Mathematical models to describe the electromagnetic behavior of electric machines, like generators, and transformers are well developed. When these components are interconnected then the magnetic flux equations become coupled. Circuit simulators decouple these components by adding shunt resistors at the interface, increasing simulation time. This paper derives the coupled equations as a single state...
This paper introduces a modeling method of Three-stage Brushless Synchronous Machines. Three-stage Brushless Synchronous Machines' model is built by SimPowerSystems module and SIMULINK module in MATLAB. This model can be used to simulate both in electromotion-state and generating state. Compared with the common model, this model have the advantages of faster simulation speed and more intuitive.
This paper presents a design method of Hinfin controller of the synchronous generator used in aircraft power supply system. A linear system model of generator is provided, and an approach of solving Hinfin control was offered. In order to manifest the control effect of Hinfin controller, a generator with traditionary PSS excitation controller was offered. The simulation results show that the Hinfin...
