The sudden short-circuit test is the gold standard for determining the equivalent diagram of wound-field synchronous machines (WFSMs). Only a single measurement is needed while the machine is in saturated mode. However, this destructive test can sign

The flexible generation of electrical energy is heavily dependent on hydropower. Advanced control systems may offer an enhanced operational security. During power system disturbances, a generator may need to operate beyond its limits to maintain a st

This paper presents a new 21-bus power system model developed using the simulation software ‘DIgSILENT PowerFactory’ representing the reduced Norwegian power transmission network. The network includes a 132 kV regional network and a 420 kV transm

Parameter optimization plays a vital role in fitting a mathematical model with experimental data. In the prior model development, some of the parameters are either chosen based on an educated guess or hit and trial method or even at random. This caus

In this paper, we extend a previous study on a totally enclosed thermal model of a synchronous generator, with temperature state estimation using experimental data. The extension includes a new formulation of the system model, with four different mod

This paper explores the effects of the ongoing energy transition on the classical bulk power generation. The rapid increase in renewable penetration changes the role of grid-connected generators significantly. Large machines have been historically op

Arc fault tests of medium voltage switchgear have been performed with reduced volume and arc energy. This has been done in order to investigate if small scale experiments can be used to predict the pressure build-up during full scale arc fault test.
