An urgent need exists to improve the quality of electrical power supplied to consumers who use sensitive equipment such as digital computer or microprocessor-controlled manufacturing facilities. Switching transient studies are normally performed on an analog computer called a Transient Network Analyzer (TNA), or on a digital computer using a program called the Electromagnetic Transient Program (EMTP). The number of TNAs is inadequate to support all the switching transient studies that need to be accomplished. While the availability of EMTP for use on advanced micro-computers has certainly provided the possibility for making switching transient studies more widespread than ever before, the amount of time involved in learning to use EMTP effectively overshadows its utility. In this study, a program called TP Editor is introduced to serve an a file developer for inputs to EMTP. TP Editor is designed to be used exclusively on AC power systems in the evaluation of switching transients. This permits the power system engineer to use raw system data, which he has available, as inputs to TP Editor. This program then transforms the data into a format acceptable by EMTP. The engineer is freed of the drudgery of verifying the consistency of data types for all of the various types of data acceptable by EMTP. A system of cross checks used in TP Editor insures that the data, is in the proper units, and that the best fit of format is used in the data formats for each individual entry into EMTP. Data is accepted by TP Editor in nearly any form that the engineer has available. TP Editor will perform all calculations necessary to transform that data to a usable form by EMTP. The TP Editor generated inputs to EMTP permit the power system engineer to concentrate his efforts on methods of improvement of power quality rather than on data format procedures.
