What is a Load Flow Study in Power Engineering

1 week ago | electrical-engineering-portal.com | Edvard Csanyi

Load flow and simulation of operating conditionsLoad flow, sometimes known as power flow, are phrases that may be used interchangeably in power engineering. This term refers to a network solution that forecasts steady-state currents, voltages, and both real and reactive power flows across each branch and bus within the system.
Behind upgrading the 50+ years old 132/11 kV substation

2 weeks ago | electrical-engineering-portal.com | Edvard Csanyi

Refurbishing an Old SubstationLet’s look at the 50+ years old 132/11 kV substation that needs refurbishing and uprating as an illustration of the complicated mix of concerns that need to be considered.
Why do power grid crashes and total blackouts happen?

3 weeks ago | electrical-engineering-portal.com | Edvard Csanyi

Technical Approach to the Grid BlackoutMinimizing the likelihood of blackouts is of the highest importance due to the significant effects that would result from partial or total blackouts in highly industrialized nations. Additional difficulties have been and will be posed by the growing use of renewable energy sources and the system’s geographic expansion through its integration of neighboring nations.
Thermal conditions of electrical equipment and temperature monitoring

1 month ago | electrical-engineering-portal.com | Edvard Csanyi

Electrical Equipment MonitoringLoose connections or worn out contact surfaces are the root causes of electrical system conduction troubles. They cause a local temperature increase, which worsens the contact quality even further as the current increases. This causes thermal runaway, which damages the insulating material at high enough temperatures. Advanced thermal monitoring of electrical equipment is actually the topic of this technical article.
Best practices in earthing of metallic fences in HV outdoor substations

1 month ago | electrical-engineering-portal.com | Edvard Csanyi

Substation fence earthingIt is recommended that all substations have a perimeter fence surrounding the area where the electrical equipment is housed. As far as security measures go, it is the first line of defense. For the extra layer of protection, competent workers working in the yard can rely on internal fences. To further restrict vehicle access to the substation, fences can be used. For an extra layer of protection, you might utilize many levels of fencing.
The intricacy of medium-voltage circuit breaker ratings

2 months ago | electrical-engineering-portal.com | Edvard Csanyi

Medium Voltage Circuit BreakersWhen you look at the IEC 62271-100 for MV breaker ratings, you will likely find a bunch of rated-something ratings. It could be hard for young engineers to catch up with all ratings, especially since several ratings are similar in wording but crucially different. This technical article will shed some light on the most important of these ratings of a medium-voltage circuit breaker.
Alarms Coming From the Shunt Reactor| EEP

The Art of Shunt Reactor MonitoringNowadays, monitoring of transformers and shunt reactors is pretty much common. However, the difference is in the nuances. There are dozens of parameters that can be monitored and the the overall cost is not negligible at all. There are many benefits of monitoring the reactor operation, and the moist important is to prevent damage that could end shunt reactor life.
Seven steps to improve visual impact of a power substation

2 months ago | electrical-engineering-portal.com | Edvard Csanyi

Substation’s visual impactThe aesthetics of the substation should be of greatest significance to the community. To ensure environmental compatibility and community acceptance, it is vital to involve the community in the early stages of a project. It is possible that environmental impact assessments were not conducted during the initial installation of several of the current substations, which date back tens of years.
What is Time Grading in Relay Protection

Mar 7, 2025 | electrical-engineering-portal.com | Edvard Csanyi

Grading operating times of the relaysWhat are time grading and relay coordination in protection philosophy? Let’s try to figure out how to grade (or rank) the relays’ operation times so that the one nearest the problem operates first. In Radial Distribution Systems, time-graded protection works well. Systems that begin with an electrical source at the top and end with a load at the bottom are known as radial distribution.
Turnkey Substation Project

Mar 3, 2025 | electrical-engineering-portal.com | Edvard Csanyi

Turnkey Substation ProjectBehind the successful execution of a turnkey substation project is always successful project management. Young engineers working on the execution of substation projects often repeat the same mistakes that often lead to unforeseen project costs. Generally speaking, management of turnkey projects can be described as monitoring and checking of various items and activities in a turnkey project based on the contract document and specification.
