Overview of Digital Input Power Meter
To fulfill the need of removing the redundancy of conventional power metering, this project will complete the following tasks:
- Develop a system to convert NxtPhase electrical transducer proprietary digital output to the 60044-8 IEC Standard data stream.
- Transmit the standardized digital data stream over a variable length optical communications channel.
- Acquire the standardized data stream using external digital hardware and a standard PC.
- Format and display digital data representing the 3-phase line voltage and current, including metering features such as harmonic distortion and power factor.
Our system consists of 3 main parts: a sinusoid generator to simulate digitally sampled line voltage and current, a merging unit to packetize the data into the IEC 60044-8 standard, and a meter to receive and display the packetized data. A simple diagram of the total system is shown below. Please click on the links for a more detailed description of it's operation.
These parts were realized with the Debug board.
Our presentation of the Digital Input Power Meter took place on July 27th, 2001 at the Engineering Lab Wing at the University of Victoria. The graphic below shows Marcie Webb beside the poster developed to explain the complete system.
