As part of UEE’s commitment to supporting renewable energy, the Cloudworks renewable energy project stands out as our largest hydroelectric project to date. The project consisted of five – two unit 15MW per unit Impulse type Six Nozzle Pelton turbine units plus a sixth plant consisting of four reaction type Francis turbine/generator units rated at a total of 50MW.
The project scope for UEE Consisted of the design, manufacturing and commissioning of the 138kV Interconnection Substation protection and control system, 8.25kV generator switchgear assemblies, generator protection system, plc based turbine/generator control system, human machine interface system, intake power control system and the balance of plant/station service subsystems.
The engineering package included complete drawings, testing and commissioning plans, quality assurance documentation, production testing reports, operations and maintenance manuals, installation cable and interconnection schedules.
Site services included all equipment testing, protection verification testing and control system verification testing. UEE also provided operator training and configuration of the remote monitoring and control station.
Run-of-River projects are particularly exciting from an electrical engineering standpoint, as they differ substantially from traditional hydroelectric projects. With minimal water storage, beyond the limited requirements to submerge the intake pipe, and no diversion of downstream flows (diverted water is returned to the stream below the powerhouse), the environmental impact is virtually non-existent.
Glacial ice fields, extreme elevation and steep, fast flowing water typify Run-of-River sites, resulting in hydroelectric power generation largely free of fish or animal habitat.
The Harrison Lake Cloudworks project includes a total of six 30MW Plants, each with 2 x 15MW Vertical Pelton units. UEE services included the Design, Manufacturing, & Commissioning of the 138kV Interconnection Substation Protection & Control System, 8.25kV Generator Switchgear, PLC Based Turbine/Generator Control System, and Station Service Subsystems.
