Genset power system having multiple modes of operation
First Claim
1. A power system, comprising:
- an engine;
a generator mechanically driven by the engine to produce electrical power directed to an external load;
a monitoring device configured to monitor a performance of the generator and to generate a signal indicative of the performance;
a performance module configured to selectively provide at least one of an alarm and a shutdown command to the engine based on the signal from the monitoring device; and
a switching device having at least a first condition and a second condition,wherein;
when the first condition of the switching device is active, output from the performance module is overridden;
the engine is operated at a reduced speed and load output, and the generator is inhibited from producing electrical power; and
when the second condition of the switching device is active, the performance module is allowed to affect operation of the power system, the engine is operated at an elevated speed and load output, and the generator is allowed to produce electrical power directed to the external load.

Abstract
A power system is disclosed. The power system may have an engine, a generator, a monitoring device configured to monitor the generator and to generate a signal, and a performance module configured to provide an alarm and a shutdown command to the engine based on the signal. The power system may further have a switching device with a first condition and a second condition. When the first condition of the switching device is active, the performance module may be overridden, the engine may be operated at a reduced speed and load output, and the generator may be inhibited from producing electrical power. When the second condition of the switching device is active, the performance module may affect operation of the power system, the engine may be operated at an elevated speed and load output, and the generator may be allowed to produce electrical power directed to the external load.

10. A method of providing power, comprising:
-
combusting a mixture of fuel and air to create a mechanical output; converting the mechanical output to electrical power; monitoring a characteristic of the electrical power; generating at least one of an alarm and a shutdown command based on the monitored characteristic; overriding the at least one of the alarm and the shutdown command, reducing the mechanical output, and inhibiting the conversion of the mechanical output to electrical power during a first mode of operation; and affecting at least one of the combusting and the converting based on the at least one of the alarm and the shutdown command, increasing the mechanical output, and allowing the conversion of the mechanical output to electrical power during a second mode of operation. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A power system, comprising:
-
an engine; a generator mechanically driven by the engine to produce electrical power directed to an external load; a monitoring device configured to monitor at least one of a voltage and a frequency of the generator and to generate a corresponding signal; a voltage regulator configured to affect performance of at least one of the engine and the generator based on the signal; a manual switch having a first position and a second position; and a controller in communication with the engine, the generator, the monitoring device, the voltage regulator, and the manual switch, the controller being configured to; selectively provide at least one of an alarm and a shutdown command to the engine based on the signal; override the signal and deactivate the voltage regulator when the manual switch is in the first position; and allow the voltage regulator to affect operation of the power system when the manual switch is in the second position. - View Dependent Claims (19, 20)
