Ingeteam, a Spanish solar inverter specialist, has supplied its central inverter solutions to five solar parks in Brazil, totaling 150 MW of PV capacity.
The agreement saw Ingeteam ship two different configurations of its 1,500 Vdc central inverter station to the northern part of the state of Sao Paulo, where the solar project is located. One such type of inverter was a 4.5 MW station that comprises a 3 MW dual inverter with a 1.5 MW central inverter.
Also shipped was the smaller 3 MW station, which is equipped solely with a dual inverter. Both iterations of the Ingeteam solution come complete with a metal platform that comprises the necessary technology to inject medium voltage power to the Brazilian grid, namely: LV/MV transformer, oil deposit, medium voltage switchgear, auxiliary services transformer, and low voltage switchgear.
The Ingecon Sun EMS Plant Controller – an Ingeteam-developed control system that enables the solar farms to implement on-demand production strategies, frequency regulation and reactive power compensation – were also supplied as part of the arrangement.
In rapidly expaning solar markets such as Brazil, the ability of large PV plants to help manage grid load is increasingly vital, hence Ingeteam’s insistence on supplying such grid-smoothing capabilities with its inverters.
Ingeteam said that its plant controller system allows solar farms to operate in a similar manner to a conventional energy generation plant. The five solar farms will host a total of 30 inverter stations, and are expected to be fully operational before the end of the year.
