MSP430F47177: ENERGY METER LIBRARY REQUIRED.

Part Number: MSP430F47177
Other Parts Discussed in Thread: MSP430F47127, MSP430F6779A

Hello ,

I want to start Development on MSP430F47177 & MSP430F47127 for ENERGY METER Project for that i require libraries for the same .

Here are the parameters i want to measure in different Network Configuration. 

Network configuration : 3 Phase 4 Wire , 3 Phase 3 Wire , 2 Phase 2 Wire , 1 Phase 2 wire.

Parameters to be measured
1. System kW. kVAr, kVA ,PF.  
2. Per phase Voltage , Current + Neutral Current , PF , kW , kVAR, kVA , Phase Angle.
3. Phase Sequence Detection.
4. Four Quadrant Measurement.
5. Harmonics 
    a. Each phase's VOLTAGE and CURRENT Harmonics upto 40th order.
    b. Total VOLTAGE and CURRENT harmonics of each phase.
    c. Harmonic & Fundamental Active Power and Reactive Power.
6. Energy Pulse Output for ACTIVE, REACTIVE,APPARENT Energy
we require sample code ph / project files which can measure all these parameter 
and energy meter library  and documents for which can guide us how to measure all this parameter.
Thank you,
Nirav
  • Hello Nirav,

    The F471xx devices are older devices which are not fully supported and I am not sure what libraries are readily available for these devices.  If you are starting a new design, I recommend looking at the newer MSP430F6779A device and related designs and Energy Measurement library.  The TIDM-THREADING design below is a good reference to get started with and includes support of the EM Design Center.

  • Hello Eddie,

    Thanks for your valuable suggestion.

    I have gone throughh ttps://www.ti.com/tool/TIDM-THDREADING  (Total Harmonic Distortion Measurement For Energy Monitoring)  that helped me to understand know how of ENERGY METER USING MSP430.

    I have have a query regarding Network system used in this method , here it is shown for 3 Phase 4 Wire star connection what if i want to find power readings for 3 phase 3 wire (Delta )  as well as 2 phase 2 wire (for ex VOLTAGE of PHASE 1 &PHASE 2  , current of PHASE 3 ??

    What will be the input circuit for that and how can i measure all power/energy/pf and other parameters?

    Best Regards,

    NIRAV
