PROJECT DESCRIPTION and SITE SPECS<\/strong><\/div>\n

[\/vc_column_text][vc_column_text]<\/p>\n

Lake Tekapo in New Zealand is the main water supply source for the whole power scheme: Tekapo “A” and “B”<\/strong>.
\nLake is dammed by the Lake Tekapo Control Structure<\/em>, a structure located behind the eponymous river that also forms the connecting bridge to local\u00a0Highway 8<\/em>.
\nBegun in 1938 and interrupted in the middle of the next decade, construction of the Plant was then fully completed in 1951.<\/p>\n

Tekapo “A” generates electrical energy through streams of water transported by a pipeline of approximately 1.4 km long suction.
\nIn 1970 an artificial channel was built along over 25 km that could intercept water backflows from the twin Plants.<\/p>\n

Commissioned in 1977, Tekapo “B” is the only power plant in New Zealand completely surrounded by water. Perched on the basin of Lake Pukaki, essentially as a sort of island, Tekapo “B” is connected to the mainland by a bridge 74 meters long and boasts an exceptional view to the mountains of Aoraki \/ Mount Cook.
\nBuilt on massive foundations in concrete raft, Tekapo “B” counts a total of 46 meters height. However, almost two-thirds of the center remains below the waterline.
\nWater supply is secured\u00a0by inflows from Lake Pukaki and from inside that basin.[\/vc_column_text][vc_separator color=”custom” style=”dotted” accent_color=”#888888″][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”10px”][vc_empty_space height=”20px”][vc_column_text css=”.vc_custom_1490968754563{padding-left: 5px !important;background-image: url(http:\/\/www.dea.mi.it\/site\/wp-content\/uploads\/2015\/11\/GIHQn.jpg?id=2493) !important;}”]<\/p>\n

IMPLEMENTED TECHNOLOGIES by D.E.A. TEAM<\/strong><\/p>\n<\/div>\n

[\/vc_column_text][vc_column_text]<\/p>\n

D.E.A., in a close partnership with ABB, worked on the revamping of 2 Francis<\/em> turbines of Hydroelectric Power Station Tekapo control system “B” and a turbine unit Koplan<\/em>\u00a0in Tekapo “A” structure.<\/strong><\/p>\n

D.E.A.\u00a0followed study and development of the turbine management adjustment while proposing customer-oriented solutions thus obtaining a measured improvement in performance for the entire control loop response time, in compliance with stringent specificications of customer.<\/p>\n

The developed adjustment system is able to steer the\u00a0enginner machine in a manner bumpless switching between modes of speed control, load control according\u00a0with local regulations.<\/p>\n

Because of the peculiarity and complexity of the process, it has also been developed a software simulation that would guarantee a response to the adjustment to reality most likely to allow the customer, during the FAT, directly test the goodness of the proposed improvements.<\/p>\n

D.E.A. technical team also supervised Commissioning for both groups and the global Commissioning phase for the whole Hydroelectric Power Station.<\/strong>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”10px”][vc_empty_space][vc_separator color=”custom” style=”dotted” accent_color=”#888888″][vc_empty_space height=”20px”][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″ css=”.vc_custom_1490969211683{background-color: rgba(255,255,255,0.01) !important;*background-color: rgb(255,255,255) !important;}”][vc_column_text css=”.vc_custom_1490969270402{padding-top: 5px !important;padding-bottom: 72px !important;}”]Download the full Reference<\/strong> for the Lake TEKAPO project.
