Abstract
A power generator system incorporates a generator driven by an engine. A case houses the generator and the engine. A controller communicates with the engine so as to control the speed at which the engine drives the generator. A temperature sensor is disposed so as to sense a temperature within the case and to send a temperature signal to the controller. The controller controls the speed of the engine depending upon at least the temperature signal received from the temperature sensor.
Claims19
A generator system comprising a prime mover, at least one generator driven by the prime mover, a case housing the prime mover and at least a portion of the generator, a controller communicating with the prime mover so as to control the speed at which the prime mover drives the generator, and a temperature sensor disposed so as to sense a temperature within the case and to send a temperature signal to the controller, the controller configured to control the speed of the prime mover depending at least in part upon the temperature signal received from the temperature sensor.
A generator system comprising a noise-suppression case, an engine, a generator driven by the engine to generate an AC voltage output, the engine and the generator being housed within the case, a temperature sensor that senses a temperature within the case, and a controller that controls engine speed and that receives a temperature signal from the temperature sensor which is indicative of the sensed temperature, the controller configured to detect a temperature rise inside the case and to determine an engine speed increase based on the temperature rise, whereby the engine speed increase is sufficient to compensate for a drop in generator efficiency that results from the temperature rise.
A generator system comprising a case, a generator, an engine driving the generator, the engine and the generator being housed within the case, a temperature sensor arranged to sense a temperature in the case, and means for controlling engine speed so as to compensate for reduced generator efficiency that is associated with a rise in temperature within the case.
A method for controlling an engine of a generator comprising the steps of:
- sensing a temperature within the generator;
- detecting a rise in temperature within the generator;
- and
- increasing engine speed when a temperature rise is detected.
A generator system comprising a prime mover, at least one generator driven by the prime mover, a case housing the prime mover and at least a portion of the generator, a controller communicating with the prime mover so as to control the speed at which the prime mover drives the generator, and a temperature sensor configured to detect a temperature of air within the case and to send a temperature signal to the controller, the controller configured to control the speed of the prime mover depending at least in part upon the temperature signal received from the temperature sensor.
