Power Transmission Company No. 3 (PTC 3) has just provided technical support to Ia Pet Dak Doa Wind Power Joint Stock Companies No. 1 and No. 2 in implementing successfully acceptance and energization of Pleiku 3 500kV substation (Pleiku city, Gia Lai province).


Pleiku 3 500kV substation was energized at 22:14 on 11 September 2021

The Pleiku 3 500kV substation (O So village, Ia Kenh commune, Pleiku city, Gia Lai province) is an outdoor, permanently manned-type substation. The substation features a high-tech integrated control and protection system. The substation is designed with three voltage levels of 500kV, 220kV and 35kV, the last voltage level being used by auxiliary equipment. In the first phase of installation, one 500/220/35kV-900MW transformer was installed.

During the project implementation, the investor was supported by PTC 3 to check and comment on documents and drawings of secondary circuits; to assist in compiling equipment operating procedures; creating best conditions and safety monitoring for construction crews to install, wire and connect equipment at Pleiku 500kV substation to ensure safety in the condition that surrounding equipment is still operating.

When the construction and installation of equipment are completed, PTC 3 has coordinated with the investor to test and accept the connection points and provided technical support to the investor in the testing and acceptance of the overall protection relay circuit at Pleiku, Pleiku 2 and Pleiku 3 500kV substations; supported energizing test of the work.

After putting phase 1 of the project into operation, PTC 3 continues to support operation management.

Pleiku 3 500kV substation has been successfully energized, ready to receive power from two wind power plants of Ia Pet Dak Doa 1 (100MW) and Ia Pet Dak Doa 2 (100MW), adding a clean energy source to the local power system to meet the power demand of the power system in general and in Gia Lai province in particular.

The Pleiku 3 500kV substation is the fourth 500kV substation that PTC 3 has provided technical support to the investors. The other substations were Thuan Nam and EaNam 500kV substations of Trung Nam Group, and EaSup 500kV substation of Xuan Thien Group.
