What is DC overvoltage fault in inverter?
2.2. DC overvoltage fault The condition of DC overvoltage fault in inverter is that the DC capacitor voltage exceeds maximum allowable voltage Umax and maintains for a period of time, which triggers overvoltage protection and causes the inverter to stop.
What causes DC undervoltage fault?
For the cause location of DC undervoltage fault, as shown in Fig. 10, the DC current Idc will have a reverse current in the case of DC short circuit. The energy of the DC capacitor is quickly released and DC voltage Udc drop causes undervoltage fault.
Can a transformer-less inverter cause DC current leakage to ground?
In photovoltaic systems with a transformer-less inverter, the DC is isolated from ground. Modules with defective module isolation, unshielded wires, defective Power Optimizers, or an inverter internal fault can cause DC current leakage to ground (PE - protective earth). Such a fault is also called an isolation fault.
Can a grid-connected PV inverter control overvoltage and undervoltage?
Generally, a grid-connected PV inverter can be programmed to inject and absorb the reactive power. Hence, both the overvoltage and undervoltage conditions can be regulated using the reactive power control ability. The dq components theory, which will be described in Section 2, can be used to perform the controlling mechanism efficiently .
