6 FAQs about [Photovoltaic inverter fault repair encyclopedia]

Can a PV inverter cause a fault?

The fault current injected by the PV inverter can reach significantly lower values than synchronous distributed generator (SDG) (Nimpitiwan et al. 2007). Despite its low fault contribution, the high PV penetration can also cause malfunction of network protection devices (Bracale et al. 2017).

Does a single phase PV inverter have a fault condition?

In addition to the three-phase PV inverter, in Gonzalez et al. (2018), a single-phase PV inverter (3.2 kVA) is investigated under fault condition when operating with grid-connected functionality. During a fault, the voltage at the PCC of the single-phase PV inverter also reaches 0.05 pu, and the test results are summarized in Table 7.

Do grid-connected PV inverters have a fault condition?

In addition, the experimental results available in the literature are specific to the PV application. Many works in the literature address the behavior of grid-connected PV inverters under a fault condition. Some of them, specifically, investigate the fault current contribution from this equipment by means of simulations.

Can a fault current limit a PV inverter?

The technique is developed by combining distance protection and overcurrent protection, and simulation results under different fault conditions show the feasibility of the proposed scheme. According to the authors, the fault current of PV inverters is limited within 1.5 times the rated current in order to avoid damage to the equipment.

Is fault contribution associated with nominal power of commercial PV inverters?

Based on the results obtained from commercial PV inverters, it can be concluded that the fault contribution is not associated with their nominal power. However, articles (Varma et al. 2016) and (Kasar & Tapre, 2018) combine these two characteristics, confusing readers.

Does PV insertion affect fault current in residential power distribution networks?

The main objective is to investigate the changes caused in the magnitude of the fault current due to the PV insertion in residential power distribution networks. In both, it is stated that the fault current of each PV system can reach a value of 1.2–2.5 times the PV inverter rated current from 4 to 10 cycles.
