6 Frequently Asked Questions about “Photovoltaic inverter AC real-time value”
How does a PV inverter work?
The main function of this inverter is to convert the DC power produced by the PV modules to AC power to be injected into the utility grid by considering specific characteristics based on the grid code. The availability of any PV power plant directly depends on the healthy inverter's operation.
Does a PV power plant need a healthy inverter?
The availability of any PV power plant directly depends on the healthy inverter's operation. The more increases for the installed inverters, the less availability loss in the case of inverter partial or catastrophic failures.
What happens if a PV inverter fails?
If any inverter failure occurs, the availability decreases. To maintain maximum availability, it is required to maintain the PV inverter runs without intermittent during sunlight hours. So, it is required to focus on the PV inverter performance and study the failure reasons to implement both corrective and preventive actions 16.
What is the THD requirement for a PV Grid-tie inverter?
As in the Mega-scale PV power plants, the grid requirement for the THD is very low and shall not exceed 5%, also the power losses due to the power electronic switches are minor or very low compared with the total rating capacity of the PV grid-tie inverter which is rated in Mega-watt.
How to measure the availability of a PV power plant?
The availability of a PV power plant is measured based on the inverter's working hours 15. If any inverter failure occurs, the availability decreases. To maintain maximum availability, it is required to maintain the PV inverter runs without intermittent during sunlight hours.
How to maintain inverter reliability?
Maintain the preventive maintenance as possible to maintain the inverter reliability as possible. Check the inverter cooling fan frequently to ensure its correct and good operation. The investigation in this paper is performed based on operation data analysis of the PV grid-connected inverter (central type) due to a real incident.
