PHT Project

550kW, MN

Year: 2013
Running Gear: Horizontal shaft Leffel Francis turbine, with Marelli synchronous generator
Scope: Control system for a new, single unit power plant at an existing dam

This was an all-new project at an existing site.  The previous powerhouse was demolished and replaced, as was all the equipment inside it.  PHT supplied the new controls, including PLC, touchscreen, Basler 11g relays, and hydraulic system to operate the wicket gates and inlet valve.  PHT also reworked the customer’s existing vacuum breaker switchgear with a digital multifunction relay.  Fiber optic networking was used to provide water level input from a remote gate house, and to allow use of a second touch screen in the remote operator’s control room.
