ION7650

Hello everybody,

 

I'm developing a multisite PME with ION7650, the customer is asking me a series of parameters but I haven't found them among the native measurements of the meter or in the standard graphic in PME.

 

The parameters are:

- Displacement power factor (I haven't found it)

- Average PF (I haven't found it)

- Working time of the meter (I haven't found it)

 

 

I would like to know if I have to develop frameworks in designer to have these measurement or if any of them is already present natively in the meter.

 

In addition, I saw:

- Crest factor of I and V : I saw they are available, but they're not present in the standard graphic

- Harmonics until the 63rd: I saw that in the standard graphic harmonics are shown up to the 15th, I need to see more.

 

Should I modify the standard graphics or is there any quicker way to have these parameters displayed?

 

Thanks in advance to whoever's gonna help me!

Re: ION7650

I'm looking at the (default) ION7650v410 with 7650_FAC-PQ_V4.1.0.0.1 framework

assuming: 4W-WYE volts mode

Displacement PF: My recomendation is to use the fundamental phase angles from the existing HME modules #1 through #6 (3s gapless 4-30 harmonic analysis). In order to compute the 3phase TOTAL displacement PF, you need to also compute the total fundamental powers.

The best implementation I can come up with on the spot uses three new ART modules.

Re: ION7650

- Displacement power factor

Not calculated on the meter by default I believe, could you possibly calculate this from the phase angle of Current Versis phase angle of the voltage?

 

- Average PF

Pf lag and PF Lead Mean from sliding demand window modules.

 

- Working time of the meter

Not sure about this, possibly connect a counter module to clock module new day/hour

Re: ION7650

For Average PF: do NOT simply use a sliding window demand module to compute a time averaging of the power factor ratio. This does not make sense mathematically to perform an un-weighted average... instead you must divide the time averaged real power [kW] by the time averaged average apparent power [kVA] (and multiply by your preffered sign convention).

Re: ION7650

I do not have the exact framework, but in older ION7650 meters (before V350), there was the "Power Availability Framework".

Looking at the ION Device Template Reference, it may be possible to re-build this. I believe this framework was taken out becuase of processing space so it may need to be trimmed down or possibly other features removed.
