Siemens and local power partner open new control centre for 21 provinces

Global engineering powerhouse Siemens and state-run energy company Electricity of Vietnam Southern Power Corporation have just opened a new main control centre in Ho Chi Minh City.

The SCADA/DMS system can be operated locally or remotely thanks to its web-based architecture

The Vietnamese energy provider (EVN SPC) had Siemens develop, design, and build the facilities in the main control centre in order to remotely monitor and control the medium- and low-voltage grids in 21 cities and provinces in the southern part of the country.

This project will significantly improve the availability and efficiency of the distribution grids in this region and reduce power outages, thus contributing to economic development.

“EVN’s new network control centre enables it to respond flexibly and cost-efficiently to current and future challenges to ensuring reliable network operation. For EVN, this means an improvement in both operational efficiency and quality of services,” said Thomas Zimmermann, CEO of Business Unit Digital Grid, Siemens’ Energy Management Division. “Equipped by Siemens’ most advanced power distribution technology, the centre will help us to remarkably improve the efficiency and reliability of the distribution network in 21 cities and provinces in the southern region of Vietnam.”

“We will be able to create sustainable values not only to the region but also to our company through higher productivity and significant cost savings,” said Nguyen Van Hop, president and CEO of EVN SPC.

The control centre technology is based on the Siemens Spectrum Power platform for network control centres, which will be used in Vietnam as a SCADA and distribution management system (DMS).

However, the control centre will not only be used for remote monitoring and to control distribution grids with capacities of 110 kilovolts (kV) and below, it can also work with the transmission grid (220 kV and above) in order to minimise losses and down times.

With the aid of Siemens grid control technology, the state-run energy company will also prepare 110 kV transformer substations for unmanned operation in the future.

SCADA (Supervisor Control and Data Acquisition) systems are used to operate and observe, control and monitor power grids, while the distribution management system with which they are combined optimises distribution grid management.

The Spectrum Power SCADA/DMS system from Siemens enables grid operators to control the grid management system and the energy flow. The system can be operated locally or remotely thanks to its web-based architecture. In addition, it helps to reduce grid maintenance costs and eliminate faults faster.
