TTG 200 Series Induction Controllers

Induction Grid

Thomson Governors has a standardized inexpensive solution for Induction Generators. The TTG 200 series is a PLC based design for ease of customer maintenance and future modifications. This controller series can be used with single or multiple unit powerplants using most types of turbine. The TTG 200 series will bring turbine speed to match the bus and provide a close to line contact output when this is achieved. The TTG 200 also contains the logic for opening and closing turbine inlet valves.

There are three methods of controlling the governor, either by wired input, or by use of the local OIT, or by remote communications. The TTG 200 is supplied for 3 wire control (i.e. start and stop pushbuttons). All methods of control are always active and the last input change is used for control. Shut-down signals always take precedence over start-up signals. When on line, the TTG 200 will maintain a preset amount of power or will optionaly regulate head level.

The TTG 200 can be used with either proportioning valves, simple 2 way hydraulic valves or motor driven hydraulic pumps for turbine control.

For more options as well as Electrical Control and Monitoring, see the TTG-250, which is the larger cousin of the TTG-200. The larger chassis and more extensive communications allows a rich selection of options.
