Leveraging AI to Identify the Root Causes of PMU Data Latency and Loss for Control Room

Currently, phasor measurement unit (PMU) data is applied in real-time across all control centers of large power systems for the monitoring and operational control of the system. The increase in data loss rates and delivery latency of online PMU data severely degrades the reliability of monitoring and control systems. Large power systems involve data collection from thousands of PMUs and phasor data concentrators (PDCs), which are located hundreds or thousands of kilometres away from the control centre (CC). The causes of PMU data quality degradation are diverse due to many contributing factors.
