Power Factor and Current Unbalance Correction in an Automotive plant that shared an electrical substation.

Company dedicated to the manufacture of engine heads for automobiles located in Saltillo Coahuila. This international company has 4 branches in Mexico and branches in the United States.

Its main problem was the non-compliance with two of the parameters of the Grid Code:

• Power Factor: Because they did not have enough reactive compensation equipment to reach a satisfactory value.
• Current unbalance: Due to the load's own unbalance as they had certain types of furnaces, which caused variability in the unbalance.

They faced the following challenges:

• Limited available area: The area for the installation of the equipment was complicated, so it was necessary to carry out a creative civil and electromechanical engineering to not only accommodate the equipment, but also to adapt it aesthetically.
• Parameter Compliance: Comply with Grid Code requirements in Power Factor and Unbalance parameters.
• Double requirements: The company was adjacent to a larger company in the same industry with which it shared a substation, which complicated the execution of the project due to safety issues. Therefore, we had to comply with the safety, electrical installation and civil works criteria of both companies during the project.

Distance between the main power supply and the main equipment: It was very long, which complicated the installation both in terms of power and control.
