Abstract：Due to the large rotational inertia of synchronous machines，frequency changes caused by faults areminimal. In contrast，new energy systems have smaller rotational inertia，which can result in more significantfrequency variations during faults. These larger frequency fluctuations inevitably lead to changes in ...

Abstract：Aiming at the scarcity of real label data caused by equipment occlusion in the construction ofsubstation 3D map，a 3D map construction method was proposed based on semi-supervised deep closest point（SEMI-DCP）. Firstly，the iterative closest point algorithm was used to generate pseudo-labels for the registered...
