Vietnam Power Relay Protection Team

Vietnam's power relay protection is supported by specialized teams and companies ensuring reliable, safe, and modernized electrical systems.Key Organizations and Service ProvidersENPOWER (Power Engineering Systems JSC) is a leading Vietnamese company providing complete Easergy MiCOM protection relay solutions for substations, transmission lines, control centers, and power plants. Founded in 2009, ENPOWER offers engineering, procurement, and construction (EPC) services, focusing on precision, innovation, and professional expertise to meet demanding customer requirements in the energy sector . Carelabs Vietnam specializes in Relay Coordination Studies, optimizing power system reliability by providing customized solutions for rapid fault clearing and safety. Their services help ensure that relays operate correctly under fault conditions, minimizing downtime and protecting equipment . Vietnam Electricity (EVN) has modernized substations using Schweitzer Engineering Laboratories (SEL) devices, which comply with IEC 61850 standards and are designed to withstand Vietnam's harsh environmental conditions. These devices enhance grid automation, fault detection, and public safety by quickly de-energizing faulty lines . ABB Vietnam provides advanced power protection and control solutions, including medium and low voltage products, distributed control systems, and measurement and analytics tools. ABB's offerings support safe, reliable, and efficient operation of industrial and utility power systems .Regulatory and Technical StandardsVietnam's relay protection teams operate under evolving regulatory standards for interconnection and fault management. With the increasing integration of inverter-based resources (IBRs), traditional protection schemes are challenged, requiring sensitive fault detection and updated relay settings. Technical support and modeling are provided by initiatives like the Pacific Northwest National Laboratory (PNNL) in collaboration with EVN's National Load Dispatch Center .Functions of the Power Relay Protection TeamFault detection and clearing: Ensuring rapid isolation of faults to protect equipment and maintain grid stability.Relay coordination: Setting and testing relays to operate in the correct sequence during faults.Substation automation: Implementing digital relays and IEC 61850-compliant devices for monitoring and control.Safety and reliability: Mitigating arc flash hazards, protecting personnel, and ensuring continuous power supply.System optimization: Conducting studies and simulations to improve efficiency and prevent unnecessary outages. Vietnam's power relay protection teams combine engineering expertise, modern relay technologies, and adherence to international standards to maintain a reliable and safe electrical grid, supporting both industrial and residential power needs.
