METHOD FOR DIAGNOSING CURRENT SENSORS IN AN INDUCTION MACHINE DURING OPERATION THEREOF |
摘要 |
A method diagnoses current sensors of an n-phase induction machine which has n−1 current sensors. The n phases of the induction machine are short-circuited for a brief period of time during normal operation of the induction machine, and the time progressions of the n−1 currents are measured by the n−1 current sensors during the short-circuit operation. The actual values of the time progressions of the n−1 measured short-circuit currents are compared to corresponding prescribed target values for the n−1 short-circuit currents. A potential fault state of one or more current sensors is determined from the comparison. |
