The PMU Connection Tester is a widely recognized, open-source Windows GUI utility created by the Grid Protection Alliance (GPA). It plays a critical role in modern Wide Area Monitoring Systems (WAMS) by allowing grid operators, engineers, and researchers to validate, test, troubleshoot, and visualize real-time data streams originating from power grid synchrophasor devices.
Phasor Measurement Units (PMUs) are high-speed, GPS-synchronized sensors that monitor grid stability by capturing electrical wave magnitudes and phase angles up to 100+ times per second. If the connection between these units and the control center fails, grid reliability is directly compromised. The PMU Connection Tester acts as the definitive tool to ensure these telemetry lines remain rock-solid. Key Features & Capabilities Releases · GridProtectionAlliance/PMUConnectionTester
