Actually it is about a virtual\u00a0synchronoscope that verifies the correct instant for the synchronization:\u00a0phase sequence of the generator must be same<br \/>\nwith the grid, the generator frequency must be equal to the\u00a0grid frequency, the generator voltages should be equal to the\u00a0corresponding grid voltages and the generator voltages<br \/>\nshould be in phase with the corresponding grid voltages.\u00a0After the conditions of synchronization between synchronous\u00a0generator and large power grid are occur, the parallel\u00a0operation of generator is realized automatically. The virtual\u00a0synchronoscope is designed from two principal components:\u00a0hardware (LEMs transducer for measurement six voltages,\u00a0supply voltage, elements for input\/output signals conditioning,\u00a0USB multifunction I\/O module) and software (virtual\u00a0instrument). The main objective of this paper is to create aneasy to use device for the study of network synchronization<br \/>\nsynchronous generators. The LabVIEW graphical programming\u00a0environment is used for designing virtual instrument.\u00a0The monitored parameters values are displayed\u00a0using digital indicators. The real-time voltage waveforms for\u00a0grid and generator are displayed. With three-phase voltage\u00a0phasors (voltage vectors) we can see the evolution of phase<br \/>\nangles and voltages amplitude. This virtual synchronoscope\u00a0can be used in engineering education from universities or intesting laboratories of electrical machines.<\/td>\n<td width=\"66\"><a href=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/2015\/27.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 is presented in a constructive and\u00a0functional way an instrument that can be used at connecting\u00a0synchronous generators at the grid supply that has a constant voltage and frequency.
