Comment pouvez-vous intégrer la surveillance de la qualité de l’énergie dans le système SCADA de votre installation ?

Integrating power quality monitoring into a facility's SCADA (Supervisory Control and Data Acquisition) system involves several steps that ensure the seamless collection, analysis, and presentation of power quality data in real-time. Power quality is a critical aspect of facility operations, especially in industries where equipment performance & uptime depend on stable & high-quality electrical power. Monitoring parameters like voltage, current, harmonics, frequency, & disturbances allows operators to identify issues before they lead to equipment failure or operational downtime. 1. Identifying Power quality parameters. 2. Choosing power quality monitoring equipment. 3. Integration with SCADA system. 4. Data acquisition and visualization.

SCADA is mainly for process control. Power Quality is something which can be monitored with PQ monitoring analysers (from Fluke) or Power quality meters that are capable of capturing higher resolution waveform and also able to record the transient events in case of any overcurrent, overload, faults or other event that might be of concern.

It is not the greatest idea to integrate power quality monitoring into SCADA since the values get averaged out to 1 min trend. SCADA however, can definitely give an initial basis to understand what might be wrong or what needs to be monitored more i.e. It will enable to determine points/feeders/equipment where you might require the Power quality to be measured.

Integrating power quality (PQ) monitoring into a facility's Supervisory Control and Data Acquisition (SCADA) system is a strategic move to enhance operational efficiency, ensure equipment reliability, and minimize downtime. Power quality monitoring captures critical parameters such as voltage, current, harmonics, transients, and frequency deviations, while SCADA systems enable centralized control and monitoring of facility operations. By combining these systems, you create a unified platform for real-time visibility and proactive management of power-related issues.

First step will be to add the power meters, protection relays, VSDs, etc into the SCADA or relevant power monitoring software (PME >>> SCADA for power quality monitoring). Power meters - Depending upon their capabilities

Depends on what platform does the site uses. If they have major devices from Rockwell, we need Power monitoring software from Rockwell. The place I work for - We have Schneider gear and I have done some research and can tell PME is the right way to go if you have all the Schneider meters, Schneider relays (SEPAMs, MICOM, etc). Using versatile Power meters like PM 8000s at the right locations will enable you to capture data you need to be able to measure Harmonics, THD, Undervoltage, overvoltage and what not. The main key here is the interpretation of the data which is now very easy to understand if you're passionate about it like me. Please reach out if you need more help or want to collab.

Everything you possibly can but the main concern is the budget. You need to decide the locations based on how the connection is made, Power rating of the equipment, how critical is the equipment, production loss due to the downtime vs investment. Remember this study is only about the analysis and the power meters will simply give the data which will suggest what is wrong or what can be made more reliable. That again will cost (PFCs, cap banks, AHF (Active Harmonic filters, etc).
