Period | Data Acquisition | Recording Time |
A | Collect the state data before the disturbance, output the original acquisition waveform | ≥0.04 s |
B | Collect the state data in the early stage of the disturbance, output the original acquisition waveform | ≥0.1 s |
C | Collect the state data in the middle stage of the disturbance, output continuous power frequency effective values | ≥1.0 s |
D | Collect system dynamic process data, output a power frequency effective value per 0.1 s | ≥20 s |
E | Collect dynamic data of the long process of the system, output a power frequency effective value per 0.1s | ≥10 min |
