Universal traveling-wave-based protection and fault location for power system

A system, comprising,

• a traveling wave device configured to analyze traveling wave data representative of a traveling wave corresponding to a fault on a power transmission system, the traveling wave device comprising:
• a processor,
• a wavelet transform component that, via the processor, transforms the traveling wave data into wavelet transform results, and
• protection components that use the wavelet transform results to output tripping signals for power transmission system protection, wherein the protection components comprise a traveling wave-based distance protection component, a traveling wave-based boundary protection component, a traveling wave-based differential protection component, and a traveling wave-based polarization-based protection component.

A machine-readable storage media, comprising executable instructions that, in response to execution, cause a device comprising a processor to perform operations, the operations comprising:

• receiving analog current and voltage information from respective current and voltage sensors coupled to a power transmission system;
• filtering the analog current and voltage information via bandpass filtering to obtain traveling wave information comprising analog current and voltage information;
• digitizing the traveling wave information into the data representing the current and voltage components of the traveling wave;
• and
• maintaining the data in storage for fault location determination.
