Electric arc furnace (EAF) acts as a source of sub-synchronous frequencies (SSFs) in the electrical network. If these SSFs lead to resonance, respective matched torsional modes of turbine-generator (T-G) shaft are excited causing torsional oscillating torques (TOTs) amplification. This may lead to gear damage, shaft fatigue lifetime reduction, severe damages to T-G shaft. This paper presents an assessment...
Steel mills in Bangladesh are concentrated in the Chittagong region. Some of these steel mills are installing electric arc furnace (EAF). EAFs generate sub-synchronous frequencies (SSFs) which may pose threat to nearby turbine-generator shaft by causing torsional resonance (TR). This paper presents an investigation into TR due to EAF operation in the Chittagong region of Bangladesh Power System (BPS)...
