Vietnam Electricity (EVN), a state-owned enterprise, is the largest power distributor, and holds a monopoly on transmission and distribution in the country. EVN runs its own large-scale hydropower and thermal power station with a total installed capacity of 76.620 MW, which contribute up to 50% of the national power generation system. The enterprise also controls three power generation corporations (GENCOs 1,2,3), one power transmission corporation (EVNNPT), and five regional power distribution corporations (for the North, Central, South and the two cities of Hanoi and Ho Chi Minh).

Mun Hean Vietnam Co. Ltd. (MH Vietnam), is proud to be a Power Quality solutions provider to EVN. MH Vietnam has provided solutions to compensate the grid’s reactive power and balance the grid’s three phases. This is through the installation of 50kvar and 100kvar Sinexcel Static Var Generators (SVG), totalling 160 sets. The installation pans across the different regional power distribution corporations across Vietnam.

MH Vietnam’s PQ team also works closely with EVN to provide a robust power quality monitoring system for its regional power distribution corporations. The cooperation started with a subsidiary Power Company, where its out-going feeder power monitor system was installed with Janitza UMG 604 power analyzers to detect and measure the amplitude of abnormal voltage sags. The other power distribution corporations under EVN followed suit; and have adopted the UMG 604 power analyzers in their respective systems for various purposes to meet their requirement in power quality assessment. EVN can also install PQ analyser to continuous monitor output of solar farm and important out-going feeders.

With the Janitza analyzers installed in EVN’s regional power distribution network, Mun Hean Vietnam’s next step is to expand EVN’s power monitoring capabilities to include remote monitoring, control switching, alert management and reporting. This is especially important to manage the growing solar farms and other important out-going feeders to the grid.
