Abstract
The application discloses a method and apparatus for determining an operational status of one or more power grid components (35) of a power grid (30). The grid components (35) have component signatures representative of the operational status of the power grid component (35). The method includes obtaining, using a monitor (20), at least one of a current waveform or a voltage waveform at a location, analyzing the obtained one of the current waveform or the voltage waveform, establishing one or more waveform data values of the waveform, accessing a database having a plurality of component signatures, and by comparison of the waveform data values with the component signatures producing one or more results representative of the operational status.
Claims6
A method for determining an operational status of one or more power grid components of a power grid comprising one or more of generators, switches, and transformers, the one or more power grid components having component signatures representative of operational statuses of the power grid component, the method comprising:
- obtaining using a monitor at least one of a current waveform or a voltage waveform at at least one location within a high-voltage part of the power grid;
- analyzing the obtained one of the current waveform or the voltage waveform at at least one location;
- establishing one or more waveform data values of the waveform;
- accessing a database having a plurality of component signatures representative of operational statuses of the one or more power grid components;
- and
- by comparison of the waveform data values with the component signatures producing one or more results representative of the operational status of the one or more power grid components.
A system for determining an operational status of one or more power grid components in a power grid comprising one or more of generators, switches, and transformers, the system comprising:
- a monitor for obtaining at least one location within the high-voltage power grid at least one of a current waveform or a voltage waveform and producing waveform data values;
- a database comprising a plurality of component signatures representative of the operation statuses of the one or more power grid components;
- and
- a processing system for analyzing the waveform data values and comparing the waveform data with the plurality of component signatures.
