Overview

The ADC energy metrology library software package implements various metrology parameters for energy measurement typical of electricity meters, power-distribution units (PDUs), and circuit breakers using high-performance, multichannel analog-to-digital converters (ADCs).

The ADC samples the output of channels at up to 8 kHz to measure the current and voltage of each leg of the AC mains. This software library can achieve high accuracy across a wide-input-current range (0.05 A to 100 A) and supports high sampling frequencies necessary for advanced power-quality features, such as individual harmonic analysis. Using an independent ADC to sample the current-sensor output provides designers greater flexibility in the choice of metrology microcontrollers when compared to application-integrated system-on-chip (SoCs) and dedicated application-specific products.

This software includes hardware abstraction layers to enable communication between an ADC and an Arm® Cortex®-Mx microprocessor (MCU), a library of metrology calculations for energy measurements, and electricity meter example application. The polyphase electricity meter application was developed and tested on an Arm Cortex-M4 MSP432P microprocessor, but can also be ported to other microprocessors using the hardware abstraction layers.

Also included is a Windows® PC GUI to display metrology parameters from the TIDA-010037 and TIDA-010036 reference designs.

Features

The software specifically supports the calculation of various metrology parameters for energy measurement including:

  • Total and per-phase active (kWh), reactive (kvarh), and apparent energy (kVAh) with pulse-generation outputs
  • Total and per-phase active (kW), reactive (kvar), and apparent power (kVA)
  • Total and per-phase fundamental active energy
  • Total and per-phase fundamental active power
  • Total and per-phase power factor
  • Per-phase voltage and current root mean square (RMS)
  • Line frequency
  • Supply-voltage dips and sags, swells, interruptions, and under and over deviation
  • Per-phase voltage total harmonic distortion (THD)
  • Per-phase current THD
  • Voltage phase-to-phase angle
  • Per-phase zero crossing
  • Fixed- and floating-point calibration factors

  • Metrology calculation library
  • Hardware abstraction layers for ADC and microprocessor
  • Polyphase electricity meter example application
  • Test report
  • Windows PC GUI to display metrology parameters for electricity meter application
  • Code Composer Studio™ integrated development environment and IAR Embedded Workbench projects
