Description
TYPE OF INDUSTRY – Chlorate Plant (Chemical Plant) at Dhaka, Bangladesh YEAR OF IMPLEMENTATION – 2014 PROBLEMS - Due to Electrolysis Process in the plant , It was not possible to operate Plant at Full load on Captive Plant (Gas Generators), Frequent Electrical breakdowns. OBSERVATIONS After conducting Power Quality Audit in the plant, following observations are made: Total Harmonic Distortion (THD) current is 15.90%, THD Voltage is 11.80%, Power Factor is 0.77, The 2nd (Even) Harmonics current is very high, which result to high voltage Harmonic Distortion on Generator. Due to this the Generators are hunting during operation and not able to operate plant at full load. SOLUTION - Digitally controlled Active Harmonic Filter Bank to control THDI & THDV and specially tuned for 2nd even Harmonics.
