Key Technologies for Power Quality Monitoring

(1) Data acquisition technology: By installing power quality monitoring equipment at critical locations, data on power quality parameters in the power supply system, such as voltage, current, harmonics, etc., is collected. Data acquisition technology includes sensor selection, wiring installation, data processing, etc.

(2) Data transmission technology: The collected power quality data can be transmitted to the monitoring center through two methods: wired transmission and wireless transmission, and the appropriate method can be selected according to the actual situation.

(3) Data processing and analysis technology: The collected power quality data can be processed, analyzed, and evaluated using methods such as mathematical statistics, signal processing, and pattern recognition to achieve real-time monitoring of the power quality status of the power supply system.

3.2 Key Technologies for Power Quality Assessment

(1) Indicator selection and standard formulation technology: Based on the actual situation and needs of the power supply system, select appropriate power quality evaluation indicators and develop corresponding evaluation standards to ensure the accuracy and reliability of the evaluation results.

(2) Data analysis and modeling technology: By analyzing and modeling the collected power quality data, the power quality status of the power supply system can be obtained, including the numerical values and variation patterns of various indicators.

(3) Visualization technology for evaluation results: The evaluation results are presented to users in a visual manner, which can be in the form of charts, curves, etc., so that users can intuitively understand the power quality status of the power supply system.

Power quality monitoringThe application fields of evaluation are very broad, mainly including the following aspects:

(1) Power supply system: Power quality monitoring and evaluation can be used to monitor and evaluate the power quality status of power supply systems, including transmission, distribution, and transformation systems.

(2) Industrial enterprises: Industrial enterprises have high requirements for power quality. Power quality monitoring and evaluation can be used to monitor and evaluate the power quality status of industrial enterprise power supply systems, identify and solve power quality problems, and ensure the normal operation of production.

(3) Commercial buildings: Commercial buildings have high requirements for the stability and reliability of power quality. Power quality monitoring and evaluation can be used to monitor and evaluate the power quality status of commercial building power supply systems, providing high-quality power supply for commercial activities.

(4) Residential communities: Residential communities have high requirements for the stability of power quality. Power quality monitoring and evaluation can be used to monitor and evaluate the power quality status of the power supply system in residential communities, timely detect and handle power quality issues, and ensure the quality of life of residents.
