Low power induction machines usually have the drawback of low efficiency and power factor. Line-start permanent magnet synchronous machines represent a good candidate at replacing them in constant speed applications. This paper presents the results obtained using a finite element analysis software package. The study aims to present the load-start performances and the generator capabilities of a 3...
The renewable energy system contains the equipment which must work in properly conditions for different operating states. These devices must have a high reliability in order to not disturb the functionality of the entire system, when some faults or defects occur during the normal running. The equipment might be monitored through traditional methods (from main parameters: current, voltage, frequency,...
Due the development of the renewable energy installations, the equipment for these systems has known substantial progress. Such equipment must meet a number of conditions both on power safety as well on the quality of energy supplied. As is recognized in literature, the power quality is given by frequency, voltage, harmonic pollution, sourceconsumer, interdependence, interdependence-source system...
