6 FAQs about [Where to connect solar power to transformer]

Which part of a solar array connects to a step-up transformer?

Inverters are the part of the solar array that connects to the step-up transformer. Inverters convert DC generated solar power into AC. They handle the wide swings in power supplied from the solar array. They also steady the voltage supplied to the step-up transformer.

How to connect a large-scale solar plant to a transmission network?

Connection of a large-scale solar plant to the transmission network should satisfy the requirements of both SEGCC and GC. For Small-Scale Photovoltaic (SSPV), the connection should satisfy both the SSPV Connection Code and the EDC.

Can a solar power plant be connected to a grid?

Using capacitors and/or reactors to meet the requirements of the P-Q chart at the PCC is acceptable. The SEGCC stipulates that, in case of a grid fault, the grid-connected solar power plant has to remain connected to the grid when the positive-sequence voltage at the PCC is above the curve shown in Figure 18.

How do you energize a transformer?

The transformer will need to accommodate, e.g. step down the voltage: from 480 V along the inverter circuit to provide 208 V to the utility side circuit. In this context, the transformer will be energized first from the utility side, and the inverter side second. Given our newly gained naming conventions, this arrangement is straightforward.

Can a solar plant be connected to a LV or MV network?

Depending on its capacity, a solar plant can be connected to LV, MV, or HV networks. Successful connection of a medium-scale solar plant should satisfy requirements of both the Solar Energy Grid Connection Code (SEGCC) and the appropriate code: the Electricity Distribution Code (EDC) or the Grid Code (GC) as the connection level apply.

How to choose a step-up transformer in a PV plant?
