This paper presents the results of a thorough analysis of failure of TSC modules in a steel mill plant. The TSCs are used to reduce the flicker level caused by the arc furnace loads used in the plant. The plant is modeled and Harmonic analysis is carried out. Statistical analysis is performed and the results are compared with IEEE 18 standard limits. The system is analyzed and the resonance modes are extracted. Site measurements are carried out, and the results, which verify those obtained by the simulations are also presented.
