Thus for drawing up, using the complete\u00a0mathematical model (BEMAS) chosen for the asynchronous\u00a0machine, of the electric balances for different operating\u00a0regimes of these asynchronous motors, it was necessary\u00a0to determine the parameters of the equivalent diagram.\u00a0Considering the complexity and large volume of computation,\u00a0the authors developed for this purpose, specific computational\u00a0algorithms. For all these computational algorithms,\u00a0computation programs have been drawn, being developed in\u00a0the programming environment Mathcad Version 7.0, of own\u00a0conception and which in principle can be used for any other\u00a0similar motors that have different nominal data. It has also\u00a0been highlighted that the starting point to establishing the\u00a0opportunity of replacing of the analyzed asynchronous motors<br \/>\noperating derated in steady state, is determining the\u00a0actual load degree that is achieved through active power\u00a0measurement for the considered regime.<\/td>\n<td width=\"66\"><a href=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/2015\/28.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-191\" src=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/wp-content\/uploads\/2015\/03\/images1.jpg\" alt=\"images\" width=\"100\" height=\"104\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Abstract In this paper, the authors present a study on the\u00a0energetic opportunity to replace derated motors of the five\u00a0mills which are in service at a power plant with other motors\u00a0by a rated power closer to the actual load.
