Genset Calibration Controller

Abstract

The invention discloses a controller for a generating set. The controller may have a memory module having stored therein calibration factors associated with the offset error, scale error, and delay error, and a processor module in communication with the memory module. The processor module may be configured to monitor at least one parameter of electrical power directed from the genset to the load, detect connection of the genset to the load, and upon connection of the genset to the load based on what the processor module monitors and at A comparison of at least one parameter measured at the load determines an adjustment for the calibration factor after the genset is connected to the load.

Description

technical field [0001] The present disclosure relates generally to calibration controllers, and more particularly to calibration controllers for generator sets. Background technique [0002] A generator set (genset) is an independent power supply module that can be continuously or temporarily connected to an external facility, such as a home, hospital or factory, to provide main, supplementary and emergency backup power to one or more external loads. Cables extend from the facility's power distribution grid to the generator sets and are selectively connected to the generator sets using load interruption devices. A genset controller, typically installed on each genset, monitors and individually controls the characteristics of the power generated by each genset and sent to the outbound utility. [0003] In some cases, the voltage and / or current produced by the genset may be too high for the genset controller to measure directly. In these cases, one or more current and / or vol...

AI Technical Summary

Problems solved by technology

[0006] While the method of the '682 patent may be helpful in calibrating power meters, the advantage is likely to be small

In particular, the method would still rely on a manual calibration process done at the factory, which, as described above, would be time consuming and of low accuracy

Furthermore, the test points utilized by the processor at the substation may not be selected to provide sufficiently accurate error determinations

Additionally, the method of the '682 patent compares the expected value during the third mode of operation, which can be problematic if the expected value does not properly match the actual value

Finally, the method of the '682 patent cannot be applied to genset controllers
