Control of a plurality of inverters connected to a common network interconnection point

In order to control a plurality of inverters (35-38) each connected to a current source on the input side and to a common network interconnection point (12) on the output side, wherein electrical variables are measured at individual inverters (35-38) and are used to control the individual inverters...

Zusammenfassung:In order to control a plurality of inverters (35-38) each connected to a current source on the input side and to a common network interconnection point (12) on the output side, wherein electrical variables are measured at individual inverters (35-38) and are used to control the individual inverters (35-38), and wherein connection systems between the individual inverters (35-38) and the common network interconnection point (12) are taken into account when controlling the individual inverters (35-38), effects of the connection systems between the individual inverters (35-38) and the common network interconnection point (12) on currents are measured, which currents are output by the individual inverters on the basis of the electrical variables measured at the location of the individual inverters (35-38). For this purpose, electrical variables are measured at the network interconnection point (12) and are related to the electrical variables measured at the same time at the individual inverters (35-38).
