The common cause of the inverter''s overvoltage is the voltage on the DC bus being too high, beyond the allowable threshold of the inverter. So what causes
Free QuoteOne thing to keep in mind with the overvoltage fault is that it only happens instantaneously at a certain time. Therefore you can only monitor the DC bus voltage stored on the inverter at the time of failure, it is not possible to measure the overvoltage at this time.
Then measure the input voltage or check the DC bus parameter at fault (you can check this parameter in the monitor parameter set of the inverter). Input overvoltage of the inverter is usually caused by a problem with the substation that increases the voltage at the inverter power supply.
There are two main reasons for the inverter overvoltage: the inverter power supply overvoltage and the inverter regenerative overvoltage. The overvoltage of the power supply means that the DC bus voltage exceeds the rated value because the power supply voltage is too high.
If the average DC bus voltage is greater than 460V, the DC bus overvoltage fault will be generated. Auto Action: DC Bus Over-voltage Fault will immediately turn-off the Inverter in hardware. The PFC will be turned off upon detection of this fault. Possibility-1 (Inverter relay is closed)
Most of the inverters now have an input voltage of up to 460V, so the overvoltage caused by the power supply is extremely rare. The protection measures for the overvoltage of the inverter vary according to the cause of the overvoltage of the inverter.
Everyone often encounters the problem of inverter over-voltage protection when dealing with inverter faults. The over-voltage of the inverter means that the inverter voltage exceeds the rated voltage. The over-voltage protection of the inverter is caused by the over-voltage of the inverter.
