3-D Design for Electrical Substations

Exploring 3-D design techniques for electrical substations BY MIKE MINELLI, & HAROLD HARKONEN, Nordmin Engineering Since the 1970s, engineering consulting firms typically have been designing substations using two-dimensional computer aided design software (CAD). This common technique produces...

New York's Path to 8.5 GW of Grid Flexibility by 2040

New York State's transition to a clean, zero-emissions energy grid could include up to 8.5 gigawatts (GW) of grid flexibility by 2040, according to a new report from the Brattle Group. This projection, while contingent on achieving ambitious decarbonization goals, illustrates how the state could...

Transient Analysis of Power Transformers Using Finite Element Method

A transformer relies on electromagnetic induction through coils to transfer electric energy between two or more circuits. Varying current in the transformer’s primary winding creates varying magnetic flux in the core, which produces varying electromotive force (EMF) or voltage in the...

Managing Fleets with GPS Integration

Integrating GPS tracking software to improve business operations BY JENNY MALCOLM, GPS Insight Software integration, the process of combining individual computing systems into a unified whole is important to electric and utility companies because it provides the full picture into all fleet...

Computer Simulation of Grounding Applications

Computer simulation of grounding applications are important for power generation and distribution. INTEGRATED’s proprietary Boundary Element Method (BEM) solver simulates various types of grounding scenarios very efficiently, especially in the HVDC domain of power/energy industries and in applications involving open regions for electromagnetic field computations.

Below is a case, where INTEGRATED’s COULOMB has been used to simulate a HVDC grounding system. The model consists of 648 volumes, which have been assigned specific conductivities....
