AI Technical Summary
Existing transformer simulation load test systems use discrete adjustment methods for signal correction, which cannot achieve continuous and smooth dynamic correction. This leads to test circuit detuning and affects the test accuracy of transformer electrical parameters and fault diagnosis capabilities.
By establishing a digital twin model, systematic measurement error sources are identified and correction parameters are generated. Combined with high-frequency synchronous sampling and a hybrid disturbance separation model, disturbance components in the test circuit are separated and compensated in real time. A compensation signal with opposite phase is injected using a dynamic capacitor compensation module to achieve active disturbance cancellation.
It improves the measurement accuracy and stability of transformer simulation tests, reduces measurement errors, and enhances testing efficiency and fault diagnosis capabilities.
