National Load Dispatch Centre of Vietnam Orders National Power Transmission Management System

Open Systems International, Inc. has been selected by the National Load Dispatch Centre of Vietnam, to supply a multi-level new Hierarchical SCADA/EMS for Vietnam’s national transmission grid. This large-scale project encompasses the replacement of four existing control systems; for NLDC and each of the three Regional Load Dispatch Centers.

Established in 1994, NLDC is the wholly owned subsidiary of Electricity Vietnam, a state-owned utility and the largest power company in Vietnam. NLDC is responsible for performing load dispatching, power market trading and other electricity activities throughout Vietnam.

The purpose of this project is to implement a Hierarchical SCADA/EMS, comprising a set of tightly integrated, geographically distributed and redundant Supervisory and Control Systems to support NLDC’s operation of the entire Vietnam bulk Interconnected Electric Power System. The four system sites include the National Load Dispatch Centre in Hanoi; the Northern Regional Load Dispatch Center in Hanoi; the Central Regional Load Dispatch Center in Da Nang; and the Southern Regional Load Dispatch Center in Ho Chi Minh City. Financing for this project is being provided by the World Bank.

The new HSEMS system is based on OSI’s monarch architecture and will include OSI’s next-generation Graphical User Interface and Situational Awareness System; Advanced Alarm Management System; Real-time and Historical Trending; Supervisory Control and Data Acquisition; Communications Front-end Processor; Historical Information System and Data Archiving; Inter-control Center Communications Protocol; Load Shed and Restoration; Automatic Generation Control and Dispatch; Short-Term Load Forecasting; Market Operations Interfaces; Network Security Analysis; Dynamic Security Assessment and Voltage Stability Analysis; Transient Stability Analysis; Operator Training Simulator; Common Information Model Interfaces; and Switching Order Management software products.

“The U.S. Government recognizes the importance of this project to improving system security and reliability, and power quality in Vietnam. We are delighted to see OSI, a U.S. company that has been successfully providing utility automation and smart grid solutions worldwide, playing a key role in Vietnam’s energy sector developments,” said Sarah Kemp, commercial counselor at the U.S. Embassy in Hanoi.

Based in Hanoi, Vietnam, EVN is a state-owned utility and the largest power company in Vietnam, engaged in the generation, transmission and distribution of electricity for the whole Vietnamese territory. EVN owns and operates four Power Transmission Companies and the National Load Dispatch Centre. EVN has an installed generation capacity of 13,934 MW and an electric network of 27,046 kilometers (16,806 mi). EVN also provides consulting services, including the design of master plans for the power sector’s development; planning for the development of the regional network; as well as the survey, investigation, design and construction supervision for various power projects, including hydro, thermal, gas-turbine, diesel and power lines.
