Benefits of power quality to Condition monitoring

Benefits of power quality to condition monitoring


Condition base monitoring

One of the basic rules of the universe is that nothing is perfect. Perfection simply doesn't exist.... Without imperfection, neither you nor I would exist - Stephen Hawking


Pros and Cons...

Power quality monitoring is used to ensure that an electrical power system is operating within acceptable limits, and to capture waveform distortion and other anomalies that may cause power interruptions or other system phenomena. It is a critical activity for some business sectors and a cost-saving strategy for others.


Condition monitoring, on the other hand, is a maintenance and reliability program that examines voltage, current, and frequency from electrical systems to detect mechanical problems or component wear in assets. It can help detect and prevent power quality issues earlier.


Therefore, while power quality monitoring is not necessary for condition monitoring, it can provide faster and more accurate information for decision making.



Combining power quality monitoring with condition monitoring can provide several benefits. Power quality monitoring can help identify conditions that might contribute to motor failure, trend parameters that could lead to long-term degradation, and provide data to reduce energy consumption. It can also help identify suitable mitigation techniques that improve power quality and understand capacity.


Condition monitoring, on the other hand, can detect mechanical problems or component wear in assets by examining voltage, current, and frequency from electrical systems. Combining these two techniques can provide faster and more accurate information for decision making.


However, it is important to note that there are also some disadvantages to combining power quality monitoring with condition monitoring. For example, power quality monitoring can be expensive and time-consuming. Additionally, it may require specialized equipment and expertise to perform the necessary measurements and analysis.


Overall, combining power quality monitoring with condition monitoring can be beneficial for detecting and preventing power quality issues earlier. However, it is important to weigh the costs and benefits of these techniques before implementing them.


Applying power quality to condition monitoring involves several techniques and procedures for the assessment of the electrical signal³. Here are some examples:


1. Deep Learning Approach: A deep learning-based approach for the identification of power quality disturbances is implemented and their performance analyzed in front of classical disturbances defined by the international standards.


2. Power Quality Tests: This includes conducting arc flash tests, harmonic analysis, load flow tests, and stability studies, among others. These tests help manufacturers better prepare for weaknesses in their system should specifically types of electrical irregularities occur.


3. Power Quality Monitoring Devices: These devices encompass the monitoring of characteristics of electric power systems⁶. A network of power quality monitors can be installed on supply systems, and their raw measurement data can be aggregated to correlate and help identify sources of disturbances.


4. Data Centers: The integration of uninterruptable power supply (UPS) systems into rack power distribution units (PDUs) represents another reason to add power quality monitoring to IT racks inside the data center. This integration can provide visibility to power issues at a power socket level.


5. Renewable Energy Systems: Condition monitoring techniques are also applied in renewable energy systems like wind, solar, and hydropower system analysis.


These examples show how power quality is applied to condition monitoring to optimize maintenance operations and prepare for potential electrical irregularities.


Summary:

  • Power quality and condition monitoring: The post explains the concepts and differences between power quality monitoring and condition monitoring, which are techniques to ensure the optimal performance of electrical systems and assets.

  • Benefits of combining them: The post lists some benefits of combining power quality monitoring with condition monitoring, such as identifying and preventing power quality issues earlier, reducing energy consumption, and improving decision making.

  • Disadvantages of combining them: The post also mentions some disadvantages of combining power quality monitoring with condition monitoring, such as the cost and complexity of the measurements and analysis.

  • Conclusion: The post concludes that combining power quality monitoring with condition monitoring can be beneficial, but it is important to weigh the costs and benefits before implementing them.
