Clarke Transform Based Fast Assessment of Switching Overvoltages in an MV Distribution Network

“…On the contrary, if the sequence quantities are available simply as an array of numerical values (as is the case if circuit simulation software is employed), apart from a few special cases there is no way to get the phase quantities back from sequence quantities [15]. This problem can be overcome by using a transform defined by a real-valued transformation matrix, such as the Clarke transform [16]. Its 0, α and β components are well suited for manipulating timedomain quantities, either analytically [17] [18] or via numerical calculation.…”
