Customer Compliance to ION Meters

[Kamal_Kant]

Hi Team,

We are working with a customer to specify ION9000 and PM8000 power quality meters. The customer has the following queries. Could you please help us provide relevant references or documents to respond to these queries?

7.   Operations monitoring

The plant will have permanently installed high speed recorders at both the inverter level and the point of connection which can be used to retrieve data from any naturally occurring network events. The Recipient must capture and store the data described below for the events described below. The Recipient must provide this data when requested by ARENA or AEMO.

Events to be captured include:

·                 Frequency deviation of more than 0.25Hz

·                 Voltage step deviation of more than 5% on any phase

·                 Voltage magnitude outside normal operation 0.9-1.1 on any phase

·                 Voltage angle change of more than 8 degrees on any phase

·                 Voltage oscillations of 0.3% or greater magnitude and more than 5 second duration

·                 Power Quality exceedances on individual harmonics or THD

Data to be captured during the following events:

·                 High resolution: 100 samples per second, store data from 10 seconds pre-event to 60 seconds post-event

·                 Low resolution: 1 sample per second, store data from 60 seconds pre-event to 300 seconds post-event

·                 3 phase voltage and current full waveform capture

·                 Angle, real power, reactive power and frequency

Following each of the first 2 years of operation, the Recipient will report on the Project’s performance during the [3] most significant disturbance events in its Operations Report (as per the Knowledge Sharing Plan) and, if requested, to the Stakeholder Reference Group. Assessment of the Project’s performance will include recreating the event in the wide area network model and comparing the modelling response to the observed response.

Thank you and Warm Regards,

Hello @Kamal_Kant,

Some of what you are looking for comes standard on the meters, some requires a little configuration of specific settings and some requires custom frameworks. The meter's user guide and ION Reference can cover documents regarding the "Burst" high speed data. 

Frequency deviation of more than 0.25Hz - relative setpoint module
Voltage magnitude outside normal operation 0.9-1.1 on any phase - Sag/swell module
 Voltage step deviation of more than 5% on any phase - Rapid voltage change (RVC) sag/swell module
Power Quality exceedances on individual harmonics or THD - depends if using Harmonic measurement module + set point module, Harmonic analyzer module other.

3 phase voltage and current full waveform capture - See meter's user guide and ION Reference
Voltage angle change of more than 8 degrees on any phase - custom framework

Voltage oscillations of 0.3% or greater magnitude and more than 5 second duration - custom framework

Likely will want some level of Software to collect data from the meter as unlikely to have 2 years of data stored on the meter. Example software is Power Monitoring Expert (PME).

Hi Charles,

Thank you so much for the response. Could you please confirm if this compliance applicable to ION9000 meters or PM8240 as well?

Best Regards,

Hello @Kamal_Kant ,

Both meters.
