The project involved reactive power compensation and harmonic filtering for a modern integrated steel plant environment where arc furnaces and rolling and finishing mills generate harmonics and consume reactive power. The plant facilities included production capacity of 600,000 TPA of hot rolled steel coils and strips and 350,000 TPA of CRGP, based on steelmaking by UHP furnace followed by continuous casting, hot rolling and cold rolling. The plant was commissioned in 1994.

The requirement focused on improving power quality by compensating reactive power demand and filtering harmonics generated by major nonlinear loads, ensuring more stable electrical performance for high-capacity industrial operations.

TCE's Scope

TCE’s scope covered design, procurement and installation of combined reactive power compensators and harmonic filters to compensate reactive power and filter harmonics generated by arc furnaces and roughing mills. TCE also proposed dynamic reactive power compensation for arc furnaces using thyristor-controlled reactors.

Impact

The solution improved power quality and electrical stability in a high harmonic, high reactive power environment by reducing harmonic distortion and supporting reactive power balance. This enhanced reliability of plant electrical systems and supported stable operation of large industrial loads connected to the grid.
