6 FAQs about [Photovoltaic substation inverter selection]

How to choose an inverter duty transformer for a solar power plant?

To conclude, the selection of an inverter duty transformer is a critical decision in the design and installation of a solar power plant. The transformer should be selected based on the maximum power output of the plant, voltage ratings, impedance, cooling method, and efficiency.

How does a solar substation work?

Due to the limitation of inverter capacity, solar substation generally connects PV modules and inverters into a minimum power generation unit, and uses double split step-up transformers to form a power generation unit module, i.e. one step-up transformer is connected in parallel with two sets of inverter minimum power generation units.

What are inverters and transformers used in photovoltaic power stations?

Inverters and transformers used in photovoltaic power stations are one of the important nuclear components of photovoltaic power stations. Inverters realise the conversion from DC to AC, and transformers realise the transmission and utilisation of electrical energy.

How a transformer is used in a PV inverter?

To step up the output voltage of the inverter to such levels, a transformer is employed at its output. This facilitates further interconnections within the PV system before supplying power to the grid. The paper sets out various parameters associated with such transformers and the key performance indicators to be considered.

Can a PV inverter integrate with the current power grid?

By using a reliable method, a cost-effective system has to be developed to integrate PV systems with the present power grid . Using next-generation semiconductor devices made of silicon carbide (SiC), efficiencies for PV inverters of over 99% are reported .

How are PV inverter topologies classified?

The PV inverter topologies are classified based on their connection or arrangement of PV modules as PV system architectures shown in Fig. 3. In the literature, different types of grid-connected PV inverter topologies are available, both single-phase and three-phase, which are as follows:
