Energized AT2 transformer
The energizing and putting into
operation of the 220kV/250MVA AT2 transformer has contributed to evacuating
capacity from Hai Phong Thermal Power Plant to power system, overcoming the
power shortage, ensuring a secure, stable power supply to Hai Phong city and
North coastal area.
Before project implementation,
the 220kV/125MVA AT2 transformer at 220kV Vat Cach substation was overloaded
after a period of operation serving the increasing load demands in the area. In
that situation, EVNNPT assigned PTC1
to implement project “Upgrade capacity of 220kV Vat Cach substation” from 2x125
MVA to 125+250 MVA.
This is the energy project of
level 1, Group C, with total cost of over VND 61 billion invested by EVNNPT; PTC1 is on behalf of EVNNPT to manage and implement the project. Participating
in the project implementation includes of Power Engineering Consultation
Company No. 4 (PECC4), One-member limited liability Power construction
Surveying and Designing Company No. 4, Dong Anh Electrical Equipment
Corporation, Joint venture marine highway transportation Company, Song Da
Construction and Services Company, EDH Technology Techniques Development
Joint Stock Company, Hoan Thien Technical and Commercial Development
Limited Liability Company, Hanoi Power Telecommunication Company, and some
subsidiaries of PTC1 such as Testing Division, Equipment Repair Division,
Mechanical transportation Division, North Eastern Power Transmission No. 2.
Despite the short duration of
power cut-off for AT2 transformer replacement (from 22h00, September 16th 2016
to end of September 19th 2016), with inconvenient climate of heavy rains, the
surrounding equipment are still online and in operation, etc all the tasks have
been completed after 3 day implementation, with an absolute safety for human
resources and equipment./.
