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 […]

Approval of the Restructuring Plan for Vietnam Electricity (EVN)
The Prime Minister has recently approved the “Master Plan for the arrangement and restructuring of enterprises under Vietnam Electricity (EVN) for the 2017–2020 period.” The objective of the Plan is to develop EVN into a powerful economic group with modern technology, management practices, and high specialization. It aims to improve labor productivity, operational efficiency, and […]
Readying Solutions for Power Supply Assurance: Part 2
Mr. Ngo Son Hai, Vice President of Vietnam Electricity (EVN), stated that due to power source development being heavily dependent on geographical conditions and primary energy resources, power plants are unevenly distributed across the country. Furthermore, electricity demand varies significantly between regions. Consequently, in recent years, the Central and Southern power systems have frequently relied […]
Readying Solutions for Power Supply Assurance: Part 1
Vietnam Electricity (EVN) reports that the national power system is entering a challenging operational phase during the peak dry season months. The peak of the dry season has always been the most stressful operational period for the national power grid. The national load forecast for the second quarter is approximately 53.2 billion kWh, representing an […]
Electricity Consumption Records Continue to Be Shattered
Vietnam Electricity (EVN) reports that electricity consumption figures for the national power system, the Northern power grid, and Hanoi have continuously hit new record highs. According to EVN, power capacity and output reached an all-time high on June 1, only for those records to be broken again on June 2. To date, the national peak […]
