System operator National Grid
Corporation of the Philippines (NGCP) has completed several projects that had
been aimed at improving electricity transmission services in Luzon grid.
The company, in particular, has
noted that it was able to energize 10 capacitor banks that could then help
reinforce voltage regulation in the country’s major power grid.
NGCP specified that “a total of 10
capacitor banks with a combined capacity of 875 megavolt-ampere reactive power
(MVAR) were energized in six of its substations.”
In the operation of an electricity
system, voltage regulation is ideally set efficiently so electricity devices
can seamlessly function – but if there is fluctuation or drop to an unwarranted
scale, power failures could ensue. Therefore, it is critically needed that voltage
regulation be coherently addressed in the operation of a power system.
“Through the installation of these
capacitor banks, we are able to ensure the quality of power which is
transmitted through our lines, especially during the summer season,” NGCP has emphasized.
It qualified that the peak-demand
months of summer had been set as a reference because that is when “the peak
period of the Luzon grid for the year is usually recorded.”
Among the projects completed by the
system operator had been the 100 MVAR capacitor bank at the San Jose substation
in Bulacan; then another 50 MVAR capacitor bank at the Cabanatuan substation in
Nueva Ecija.
The other energized capacitor banks
had been at substations in Binan, Laguna; Mexico in Pampanga and Dasmarinas in
Cavite; as well as Tuguegarao substation in Cagayan Valley in North Luzon.
Beyond these completed facility
reinforcements, NGCP indicated that it will “upgrade two more capacitor banks
in its Mexico and Cabanatuan substations,” and these are due for completion and
energization this June.
