Siemens contracted to improve Vietnamese power grid

Siemens has received an order to improve the performance of the Vietnamese
power transmission grid.

The work is in line with Vietnam's drive to develop a more reliable national
power supply.

Siemens' client is the state-run energy company, Electricity of Vietnam
National Load Dispatch Centre (EVN NLDC) and the company will supply and
install products and systems for detecting and evaluating failure situations
in the grid, for ensuring grid quality and for detecting and monitoring
dynamic grid states.

The equipment will be installed in substations distributed throughout the
country and in the grid control centers, where it will help increase the
grid's failure tolerance, improve its transmission capacity and optimize the
expansion of new primary plants.

The goal is to make better use of the existing grid infrastructure and to be
able to connect additional loads as well as prevent outages that could
result from overloading. The substations and control centers are expected to
be equipped with the new technology and go into operation by mid-2018.

Fault recorders from the Siprotec 5 7KE85 series, combined with the Sicam
PQS evaluation software, will be used in 73 Vietnamese substations, and the
Siguard PDP wide-area monitoring system will be employed in three regional
and one national grid control center. These fault recorders work with an
integrated function for measuring synchrophasors to monitor grid dynamics
and measure grid quality.

The Siguard PDP (Phasor Data Processor) wide-area monitoring system in the
one national and three regional control centers will also help ensure that
the transmission grid in Vietnam operates reliably. It uses synchrophasors
in real time, making it easier to quickly assess the current condition of
the grid. For example, power swings and fluctuations are immediately
displayed to help the control center personnel determine the cause of the
problem and immediately take corrective action.
