Transmission & Distribution Technology
Tree Springs. Western Power will ultimately purchase the 70 km line as a part of the Mid West Energy Project. Te transmission line that runs between Eneabba, Tree Springs and then out to the Karara mine is already providing a power supply for the mine. In US news, ITC Great Plains, in conjunction
with Western Farmers Electric Cooperative (WFEC), has placed its Hugo-Valliant high-voltage electric transmission line and substation project into service in south-eastern Oklahoma. Te 18 mile, 345 kV line and 345 kV/138 kV sub station were implemented to reduce system congestion, provide more efficient and cost-effective transmission of energy and increase access to a broader range of generation resources. Te sub station, near WFEC’s Hugo power plant, provides a link to the WFEC 138 kV transmission system. ITC’s investment in a new high-voltage
infrastructure in the Southwest Power Pool region is founded upon open access to the grid and collaboration with key energy stakeholders. Te partnership with WFEC was crucial to the successful development of the Hugo-Valliant project. “Completion of the ITC 345 kV project should
reduce transmission congestion, improve reliability and reinforce long-term economics of the Hugo Plant,” said Gary Roulet, ceo of WFEC. “Access to regional generation resources should positively benefit consumer electric bills.” Meanwhile General Electric has signed an equipment supply contract worth US$16.5m (€13m) with Power Transmission Company No. 4 to double Vietnam’s existing power capacity through upgrading of the country’s national backbone transmission system. GE’s series capacitor banks will be installed as
part of the upgrade of the 500 kV Pleiku–Phu Lam transmission line to increase power capacity from 1000-2000A.
“Te 500 kV Pleiku-Phu Lam transmission line, which is 500 km in length, is the backbone of Vietnam’s north-to-south power transmission. Increasing the capacity of the line to transmit power across the country more efficiently will enable EVN to mobilise generation sources to more effectively meet power demand, which varies from region to region. When it comes into operation in 2013, the project is expected to supply approximately 800 MW to the southern area,” said Dang Phan Tuong, chairman of the board of management of NPT. Under the terms of the contract, GE will supply
six series capacitor banks to NPT and provide on-site supervision for installation testing and commissioning. Te project uses GE’s latest fuseless technology to enable a 100 per cent increase in the current capacity of the existing transmission line and installed infrastructure. GE will partner for the first time with a local corporation, 3C Co, to provide local content for the project. Tis is the second time GE has signed a contract directly with NPT. Te first involved a similar capacitor banks installation in the 500 kV Da nang-Ha Tinh transmission line. ●
