Adaptive provision of protection function settings of electrical machines
First Claim
1. A computer-implemented method, which, when executed by a computer, causes a processor of the computer to perform the following computer-executable acts:
- acquiring data indicative of operating conditions of a generator that is protected by a protection device, wherein the protection device includes one or more protection functions;
iteratively providing settings for the one or more protection functions to the protection device based at least in part upon physical parameters of the generator that are determined based at least in part upon the acquired data; and
protecting, via the protection device, the generator using the one or more protection functions with the iteratively provided settings.

Abstract
A protection setting determiner (118) adaptively updates settings of protection functions in memory of a protection device (106) that protects a machine (102) that provides power to a power system (104), wherein the settings are updated based at least in part upon sensed data acquired during operation of the machine (102). A physical parameter determiner (110) receives the sensed data, which includes three-phase voltage and three-phase current values at the terminals of the machine (102), and uses any suitable real-time or off-line parameter estimation technique (such as Kalman Filtering for an augmented state) to determine physical parameters of the machine (102) and the power system (104). The protection setting determiner (118) uses the physical parameters to update the protection settings.

12. An apparatus, comprising:
at least one processor that repeatedly estimates physical parameters of a generator that provides power to a power system and that configures settings for one or more protection functions in a protection device that protects the generator, wherein the settings of the protection functions are based at least in part upon the estimated physical parameters, and the protection device employs the one or more protection functions, using the processor configured settings, to protect the generator. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method, comprising:
-
acquiring, via a processor, data indicative of operating conditions of a generator, wherein the generator provides power to a power system, and the generator is protected by a protection device that includes one or more protection functions; iteratively both determining, via the processor, settings for the one or more protection functions of the protection device and providing, via the processor, the determined settings to the protection device, wherein the settings are determined based at least in part upon physical parameters of the generator that are determined based at least in part upon the acquired data; and using, via the protection device, the iteratively provided settings with the one or more protection functions to protect the generator. - View Dependent Claims (22, 23)
