US 2015/0028682 A1 · SOLAR ENERGY GENERATION SYSTEM, MEASUREMENT MODULE AND POSITIONING METHOD

Abstract

A solar energy generation system a measurement module and a positioning method are disclosed herein. The positioning method is adaptable to a power generation system having AC generation modules. Each of the AC generation modules generates an output current and is electrically connected to each other in a power-supply network. The positioning method includes the following operations: (a) measuring AC currents or node voltages generated by the AC generation modules at different positions in the power-supply network to obtain current parameters or voltage parameters; and (b) determining a sequence of relative positions of the AC generation modules by calculating the current parameters or the voltage parameters.
