Power System Stability projects


One of our readers, Nico sent us an article about a very interesting and essential topic; Power system stability. Happy reading and don’t forget to share your thoughts in the comments :)

Hello fellows,

Stay in constant synchronization of multiple elements in a Power System has become an extremely important task in the operation of Power Systems; this result is due to the expansion of the electric power systems that increased the interconnection of generating stations and the various load centers.

When a surge arises in case of lighting strike or a switching impulse, which could be the cause for insulation deterioration and at the end dielectric breakdown. This is a severe process, that depends on several factors, such as the frequency at which the transformer is exposed, the configuration of the system, the application of the component etc.

electrical power surge

Motors and distribution transformers are constantly exposed to fast surges, when they are switched by circuit breakers. Reigniting occurs during the switching of motors and transformers with vacuum circuit breakers, because of their ability to interrupt high-frequency currents.

This article presents the analysis of the measured and calculated voltages along the high-voltage winding of the transformer.

In this article you will read about the technical and economic analysis for the optimal location of installation of 2 autotransformers with voltage ratio of 400/110 kV, which are equipped with automatic load regulation.

This article is a feedback from an electrical project. It was written and sent to us by your fellow electrical engineer Mile from Macedonia :) Let’s begin!
