Publication number: 20240146099Abstract: A load shed module configured to be connected in series between a power supply and a load is disclosed. A separate load shed module is connected in series between each load and the power supply. The load shed module determines the frequency of the voltage supplied from the power supply. Based on the frequency, the load shed module determines if utility power is connected or if a generator is connected. If the generator is connected and the frequency of the voltage goes outside of a desired operating range for a preset time, the load shed module disconnects the load from the power supply. Each load shed module includes a priority setting and reconnects its corresponding load after a predetermined time corresponding to the priority setting.Type: ApplicationFiled: October 17, 2023Publication date: May 2, 2024Applicant: Generac Power Systems, Inc.Inventors: Brendan Pancheri, Greg Wischstadt, Robert Iles, Andy Phillips, Taesik Yu, Sungmin Lee

Patent number: 9979337Abstract: A method of controlling operation of a variable speed, constant frequency generator system is disclosed. During operation, loads may be added to or removed from the output of the generator system. A controller monitors the power output by the generator system and detects a change in the output power exceeding a predefined threshold. The change indicates the addition of a large electrical load. The controller quickly detects the change in power output and activates a relay to disconnect the load from the generator system. The controller then accelerates the engine of the generator system to maximum speed and reconnects the load to the output of the generator system.Type: GrantFiled: April 24, 2014Date of Patent: May 22, 2018Assignee: Generac Power Systems, Inc.Inventor: Robert Iles

Patent number: 8558512Abstract: An electrical generator has an engine that provides a mechanical output that is converted to electrical current by an alternator. The engine is started by a battery-powered motor starter. The battery is charged during running of the electrical generator by a portion of the electrical current output by the alternator. The battery is charged according to a charging profile based on the temperature of the battery at start up of the electrical generator.Type: GrantFiled: January 18, 2011Date of Patent: October 15, 2013Assignee: Generac Power Systems, Inc.Inventors: Robert Iles, Alan Dietrich, Steven Wilcox, Greg Wischstadt, David Thimmesch

Patent number: 6863034Abstract: A method is provided for controlling a bi-fuel generator set. The generator set includes a controller, a generator for generating electrical power, and an engine for driving the generator. A flow of gaseous fuel is provided, and operation of the engine and the generator is monitored. The flow of gaseous fuel is adjusted in response to various predetermined operating conditions on the engine. In addition, the flow of gaseous fuel may be selectively passed through a charge cooler remote from a radiator for the engine. The flow of gaseous fuel may be cooled by the charge cooler in response to certain operating conditions on the engine.Type: GrantFiled: January 17, 2003Date of Patent: March 8, 2005Inventors: Robert D.

Patent number: 6365982Abstract: A method for controlling the speed of an engine driving a generator supplying electrical current to a load includes the steps of monitoring the current, increasing the speed when the current increases and decreasing the speed when the current decreases. The governor apparatus used to carry out the method includes a microcontroller having a current and frequency look-up table embedded in it. For some part of the monitoring step, the engine runs at a first speed, e.g., idle speed, or some moderate speed above idle speed. The increasing step includes detecting an increase in the current to a value, determining from the look-up table the frequency corresponding to the value and increasing the speed of the engine until the frequency of the current is the frequency corresponding to the value. To state it in other words, the new method and apparatus control the engine at a modest speed when the generator is unloaded or lightly loaded and increases engine speed and current frequency with increases in generator load.Type: GrantFiled: March 30, 1999Date of Patent: April 2, 2002Assignee: Generac Power Systems, Inc.Inventors: Robert Iles, Robert D.
