Equipment manufacturer Gilkes has been awarded a contract by Scottish energy company SSE plc to supply turbine, generator and control system packages for compensation flow management at three existing hydroelectric plants.
The deal includes a Pelton turbine for the 2.4-MW Glen Lussa and Turgo turbine for the 1.3-MW Nostie Bridge projects, located near Peninver and Auchtertyre, respectively. Both projects will also be fitted with manual spear valves that will be set to pass their required compensation flows at minimum heads, the company said.
“Manual actuation reduces the system complexity requiring minimal intervention from station operators,” Gilkes said in a release. “Both turbines will be fitted with a deflector system that will engage in a failsafe manner in the event of load rejection. This will allow for an uninterrupted flow through the system whilst protecting the rotating assembly of the turbine.”
The third portion of the contract includes the supply of a Francis turbine for 2.5-MW Cuaich plant in Glen Truim. The turbine will be fitted with a synchronized bypass line.
“In the event of a load rejection, the Gilkes supplied control system will send a signal for the bypass line to open in failsafe manner to ensure that the compensation flows are maintained whilst the turbine is put through a controlled shut down sequence,” Gilkes said.
HydroWorld.com most recently reported on Gilkes in June, when the company began construction on a trio of projects at the Attadale Estate.
Gilbert, Gilkes & Gordon Ltd. is exhibiting this week at HydroVision International 2016 at Booth No. 527.
