For Larger Induction Generators and for more complex Induction Control, Thomson Governors has the TTG-250. This product is also a PLC based design for ease of maintenance and the ability to modify functionality at any time. The four option card slot and open ended design allows for many more options such as Kaplan Double Regulation, Spear coordination for Turgo and Pelton Turbines, Head Level control and Communications / Networking Options. THe TTG-250 is always supplied with an Integrated Electrical meter from which that it continuously obtains electrical monitoring and protection, and an Operator Interface, providing local information and messaging, and allowing keypad parameter entry and start-stop control.

This controller series can be used with single or multiple unit powerplants using any type of turbine. The TTG 250 series will bring turbine speed to match the bus and provide a close to line contact output when this is achieved. The TTG 250 also contains optional logic for opening and closing turbine inlet valves.

The TTG-250 allows for three methods for basic control, which can be done by either wired pushbuttons, by use of the local Operator Interface keypad, or by remote communications. When on line, the TTG 250 will maintain a preset amount of power or will optionally regulate head level. There are a number of Communications Options that can be selected from including the ability to be Internet accessible.

The TTG 250 can be used customized for turbine actuation using hydraulic proportioning valves, simpler hydraulic valves and also motor driven hydraulic pumps.
