Design, Supply, and Installation Projects for Water Pumping Systems – Cooling Water System for Steel Melting & Casting Line
The calculation and design work for the pumping system of the melting, casting, and steel rolling line was initiated by Anh Minh from a technological survey and definition of demands for each water circuit (recirculating cooling, closed cooling, high-pressure water, recovery-treatment). Anh Minh’s engineers calculate flow, head, pipe losses, and NPSH to prevent cavitation. Based […]
Harmonic Filtering and Power Quality Stabilization Project – Supply & Installation of APF System
Anh Minh deployed an Active Power Filter (APF) solution at 400V voltage level, addressing typical issues of rolling lines such as high THD, cable/MCC overheating, control equipment interference, capacitor lifespan reduction, and risk of line stoppages. The system is configured at 1000A with 03 APF cabinets, accompanied by a measurement system (CT) and switchgear cabinet, […]
Harmonic Filtering and Power Quality Stabilization Project – Supply & Installation of Equipment for SVG Project – 04x32MVAR/22kV
Anh Minh participated in developing a dynamic reactive power compensation solution for the Induction Furnace cluster and non-linear loads, where low cosφ, voltage fluctuation/flicker, harmonics, and unbalance often occur on the 22kV busbar (110kV connection point). The proposed plan configures 50 Mvar for each operating cluster (comprising 30 Mvar SVG fast control and 20 Mvar […]
Harmonic Filtering and Power Quality Stabilization Project – Supply & Installation of Equipment for SVC Project – 30MVAR/22kV
Anh Minh conducted surveys and power quality measurements at the 110/22 kV substation, identifying phenomena of over/under voltage, harmonic distortion, flicker, and frequency deviation caused by Induction Furnace loads and rolling lines. From actual measured data and simulation, we designed a Medium Voltage SVC solution integrating a Thyristor-controlled branch and multi-stage filter branches to compensate […]
Harmonic Filtering and Power Quality Stabilization Project – Supply & Installation of Equipment for SVC Project – 26MVAR/22kV
Anh Minh performed a power quality assessment, recording typical issues of Electric Arc Furnaces (EAF) such as low cosφ, voltage fluctuation/flicker, harmonics, and phase unbalance, which increase failure risks and affect production line stability. From the operating data, we proposed an SVC system connected at the 13.8kV busbar, featuring a fast-control TCR configuration combined with […]
