Efficient Implementation of Revenue and Power Quality Functions on a Processing Device

Strategic Insights

— 1 min read

Researchers at Schneider Electric Usa Inc. have developed an innovative method for efficiently implementing revenue and power quality functions on a processing device. This method, patented by Erin C. McPhalen, enables the simultaneous processing of power quality and revenue data, resulting in improved efficiencies and reduced hardware requirements.

The patent describes a system that receives an analog input signal, oversamples it, and then separates the data stream into two independent paths for filtering and decimation. The first path generates a power quality stream, while the second path generates revenue data. This approach allows for efficient calculations of both power quality and revenue, while also meeting International Electrotechnical Commission (IEC) 61000 4-30 current requirements.

The patent claims highlight key aspects of the method, including the use of an Analog-to-Digital Converter (ADC) to oversample the input signal, and the implementation of a Finite Impulse Response (FIR) filter to simplify Finite Fourier Transform (FFT) calculations. The patent also describes a device that includes a converter, a filter section, a decimation section, and a processor, all of which are capable of implementing the described method.

Key Takeaways:

  • The patented method enables the simultaneous processing of power quality and revenue data, resulting in improved efficiencies and reduced hardware requirements.
