Abstract
A control system for use with a genset is disclosed. The control system may have a bus configured to receive power from the generator set, and a first sensor configured to generate a first signal indicative of a characteristic of power on the bus. The control system may also have a second sensor configured to generate a second signal indicative of an engine parameter of the generator set, and a controller in communication with the first and second sensors. The controller may be configured to synchronize an electrical output of the generator set with the power on the bus based on the first and second signals.

A control system for use with a generator set, the control system comprising:
- a bus configured to receive power from the generator set;
- a first sensor configured to generate a first signal indicative of a characteristic of power on the bus;
- a second sensor configured to generate a second signal indicative of an engine parameter of the generator set;
- and
- a controller in communication with the first and second sensors, the controller being configured to synchronize an electrical output of the generator set with the power on the bus based on the first and second signals.
A control system for use with a first generator set and a second generator set, the control system comprising:
- a first sensor configured to generate a first signal indicative of an engine parameter of the first generator set;
- a second sensor configured to generate a second signal indicative of an engine parameter of the second generator set;
- and
- a controller in communication with the first and second sensors, the controller being configured to synchronize an electrical output of the first generator set with an electrical output of the second generator set based on the first and second signals.
A method of providing power, comprising:
- monitoring a characteristic of power on a bus;
- operating a generator set to produce an electrical output;
- sensing an engine parameter of the generator set;
- and
- synchronizing the electrical output of the generator set with the power on the bus based on the characteristic and the engine parameter.
A method of providing power, comprising:
- operating a first generator set to produce electrical power;
- monitoring a first engine parameter of the first generator set;
- operating a second generator set to produce electrical power;
- monitoring a second engine parameter of the second generator set;
- and
- synchronizing an electrical power output of the second generator set with an electrical power output of the first generator set based on the first and second engine parameters.
A power system, comprising:
- a common bus;
- a first generator set having a first engine drivingly coupled to a first generator to produce electrical power directed to the common bus;
- a second generator set having a second engine drivingly coupled to a second generator;
- a first sensor configured to generate a first signal indicative of a characteristic of power on the common bus;
- a second sensor configured to generate a second signal indicative of an engine parameter of the second generator set;
- and
- a controller in communication with the first and second generator sets and the first and second sensors, the controller being configured to synchronize at least one of a frequency and a phase angle of the second generator set with the frequency and phase angle of the first generator set based on the first and second signals.
