THE CHARACTERISTIC OF THE IDLING OF THE SYNCHRONOUS GENERATOR ON THE BASIS OF THE ASYNCHRONOUS MACHINE WITH THE PHASE ROTOR
The characteristic of idling of the synchronous generator on the basis of the asynchronous machine with a phase rotor is the dependence of EMF of the stator on excitement current at the opened external chain, i.e. at the loading current equal to zero. In work expression of EMF for the range of its change close to rated voltage, from excitement current is being offered. The received empirical dependence will allow to receive in the settlement way with use of the IBM external, adjusting and load characteristics of synchronous generators. Thus the external characteristic is the dependence of tension on an anchor winding at change of current of loading (anchor current), at a direct current of excitement and power factor. The adjusting characteristic represents the dependence of current of excitement on loading current at nominal rates of tension on clips of the generator, frequency of rotation and power factor. The load characteristic call dependence of tension of the generator on excitement current at a direct current of loading (anchor current), purity of rotation and power factor. At research of the characteristic of single current the asynchronous machine with a phase rotor like AK 51-4 was used. The supply of a rotor winding of this machine was carried out by a direct current on two of its phases. The experimental data for the creation of the characteristic of idling were fixed in natural units of measure, their approximation for values of the EMF close to nominal size, allowed to establish empirical dependence of members of this characteristic in relative units of measure.
