TM


► Measurement period • Allows the precise definition of the measurement period • Repeatable

► Granularity • The PDB resolution is at the bus speed, ie at up to 25MHz • Granularity as small as 40nS within the measurement period

► Repeatable and precise sampling • The PDB ensures samples are taken at the correct time relative to the measurement period thus improving overall

accuracy of energy calculations ► Precision periodic measurement period

• The measurement period is the inverse of the number of samples per cycle times the line freq, IE sampling period is 1 / (samples per cycle * line freq)

• E.G., 50Hz Europe is 1/(64*50)=> 312.5uS, 60Hz US is 1/(64*60)=>260.4uS ► Variation in line frequency

• As the line frequency changes the PDB can easily be reprogrammed to take into account the line frequency thereby maintaining the power calculation algorithms are operating over the correct energy period (seconds)

► Environmental compensation • By measuring ambient temperature and load current the correct phase lag/lead error of the sensor (eg CT or shunt) can

be compensated for ► Digital compensation

• Precision compensation through timing removes need for external RC filter for low load current compensation • Digital timing alleviates the impact of capacitor ageing and thus extends the operational life of the meter before requiring

re-calibration ► Low processor overhead

• The PDB initiates measurements of up to 2 channels on up to 4 ADC's without consuming any processor time • The PDB interrupts the processor AFTER the sampling of all voltage and current measurements in the measurement

period significantly reducing interrupts associated with traditional approaches, eg 3-phase measurement of 4 current and 3 voltage measurements results in 3840(64*60) rather than 26880(64*60*7) interrupts for 64 samples/cycle @ 60Hz

Power Line Modem Reference Design based on 56F8025This PLM modem uses the frequency band 'A' of the CENELEC directive (frequency band 3-95kHz) reserved for energy providers (not consumer home networks). The PLM application is based on the Freescale DSP56F8025/23 (Hawk V2) family.

S-FSK (Spread FSK) modulation is used for communication, and both S-FSK modulation/demodulation routines are fully handled by the DSC software.

Power Line Modem baud rate is 2400bps and data consistency is secured with FEC (Forward Error Correction Reed-Solomon codes with erasure) methods. Modems use the 'repeating' technique to reach larger distances in harsh environment (targeting typically 500-1000m from the central node).

►First rough estimate:

• raw data rate: 250-300kbps, max. real data rate 25-30kbps• CPU core power to be explored, heavy IFFT/FFT computations, 10-30MMACs

expected, MAC unit required, modulo calculations, bit reverse addressing needed• receive sample rate 500kSamples/s (A/D with DMA (or equivalent) reqd’)• transmit sample rate 500kSamples/s (D/A with DMA (or equivalent) reqd’)• RAM needs to be explored, expected several 20-30kB, for buffers, FFT, etc.
