Mineirão world cup stadium PV plant — A case study

This paper presents a case study about a PV plant installed on the Mineiräo world cup stadium located in Belo Horizonte, Brazil. An unstable behavior on the line to neutral voltage has been identified on the commissioning of the inverters threatening the loads connected to the transformer and the equipment of the power systems. The root cause of the problem has been identified and a solution to it proposed. Simulation and measurements taken on the actual plant validate the solution and are also presented.
