Advanced Modeling of Electromagnetic Transients in Power Systems
Simulation of fast and slow dynamic behavior of electrical power systems is needed for many industrial applications. The results influence the development of electrical and mechanical components and the design of control elements in power systems. Examples are Mechanical stresses on network elements Control systems of turbines and generators Settings of protective relays Transient stability of ...
متن کاملPanel Session on Data for Modeling System Transients Determination of Rotating Machine Parameters for Transients Simulations
A rotating machine is a very complex device that involves electrical, mechanical and control systems. Therefore, the whole representation of a machine requires the specification of electrical and mechanical parameters, as well as control system data. The representation of the mechanical part and the control systems are only needed for low frequency transients [1]. An accurate representation of ...
متن کاملAccurate Average Value Modeling of Synchronous Machine-Rectifier System Considering Stator Resistance
An accurate average value model of synchronous machine-rectifier system considering the effect of stator resistance is derived in this paper. A proper voltage-behind-reactance synchronous machine model without any approximations is used for the generator that allows effective calculation of commutation displacement angle. All rectification modes of the rectifier are studied. A detailed switchin...

متن کاملNumerical Oscillations in Electromagnetic Transients Programs
The Electromagnetic transients progr am and its variants all use the “trapezoidal rule” numerical integration method. The trapezoidal rule is a second order numerical integration technique that is simple to implement. However, it is also susceptible to numerical oscillations when differentiat ing step changes in voltage and current. The program user should be aware of the potential for these os...
