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...
Photovoltaic (PV) technology permits us to harness and transform solar radiation into electricity. However, PV power generators are still a marginal share in the global power generation capacity. One of the main reasons for it is that PV systems are greatly dependent on the atmospheric conditions affecting their operation. Furthermore, series connection of PV cells is prone to power losses when the...
This paper presents the development and validation of a generic synchronous machine model to be used in real time power plant training simulators. The model accurately simulates a wide range of training scenarios including normal operation, malfunctions, and specific equipment symptomatic tests. The model developed is based on IEEE's Model 2.2 (a sixth order model) with modifications added in order...
