Description
Summary:	This paper describes the experience of a Spanish distribution utility, Union Fenosa Distribution, when implementing an off-line state estimation tool intended to work on cases comprising a diversity of voltage levels and coming from a variety of sources (own SCADA, external equivalent provided by the TSO, past records, etc.). This implies manipulating current magnitudes and transformer tap changer settings along with more usual information such as voltage magnitudes and power measurements. This tool has made it possible the automatic generation of suitable base cases, which can be subsequently used to undertake routine network studies (contingency analysis, planning problems, etc.).
