System and method for controlling turbine speed using torque converter

A system comprising a controller, the controller comprising a processor configured to:

• receive a first signal indicative of a current speed of a turbine system;
• transform the first signal into a second signal;
• transmit the second signal to control a desired speed of the turbine system by actuating an actuator;
• determine an output power of the turbine system;
• and
• determine the fluid level in the torque converter based on the output power of the turbine system;
• wherein the actuation of the actuator is configured to control a fluid level in a torque converter mechanically coupled to the turbine system to arrive at the desired speed, and wherein the desired speed comprises a first speed below a minimum drive line mechanical speed of the turbine system.

A tangible non-transitory computer readable medium comprising instructions that when executed by a processor cause the processor to:

• analyze a first signal indicative of a current speed of a turbine system;
• transform the first signal into a second signal;
• transmit the second signal to control a desired speed of the turbine system by actuating an actuator;
• determine a power output of the turbine system;
• and
• determine the fluid level in the torque converter based on the power output of the turbine system, wherein the actuation of the actuator is configured to control a fluid level in a torque converter mechanically coupled to the turbine system, and wherein the desired speed comprises a first speed below a minimum drive line mechanical speed of the turbine system.
