Water turbine pressure steel pipe dynamic vibration deformation evaluation method based on microwave radar

The invention discloses a water turbine pressure steel pipe dynamic vibration deformation evaluation method based on a microwave radar, and the method comprises the steps: 1, collecting the rotating speed of a unit, an outlet switch of a generator, and an active power signal of the unit, and recognizing whether the unit enters a normal shutdown condition or an accident emergency shutdown condition; 2, collecting a multi-point synchronous vibration waveform signal based on a microwave radar, storing the multi-point synchronous vibration waveform signal into a time sequence, synchronously recording a unit rotating speed signal into the time sequence, and stopping collection until the unit rotating speed reaches a threshold value; and step 3, extracting process basic displacement and deformation characteristic parameters, extracting process vibration characteristic parameters, extracting process resonance signal characteristic parameters, and performing characteristic evaluation aiming at a normal shutdown worki
