Paralleling Dissimilar Generators: Part 2 – Compatible Alternators
نویسنده
چکیده
Paralleled alternators are compatible if they can operate in parallel without having damaging or disruptive neutral currents flowing between them. The magnitude of neutral current flow related to the dissimilarity between paralleled sets depends upon the shape of their voltage waveforms. Depending on the generators’ temperature rise characteristics, age and insulating ratings, neutral current flow between generator sets is not necessarily damaging. Be aware that neutral currents can also cause disruption in protective relay operation, particularly for ground fault sensing. Voltage waveform harmonics

Paralleling Dissimilar Generators: Part 3 – Load Sharing Compatibility
Generator sets cannot operate in a stable fashion in parallel with other sources unless the loading on the generator set is controlled. When generator sets are operating together on an isolated bus (that is, not grid-paralleled), they are commonly provided with equipment to allow each machine to operate at the same percentage of load as the percentage of load on the total system. This is termed...
متن کاملDesign of Direct Driven Alternators for Renewable Energy Applications
Permanent magnet generators for renewable energy application have been subject of research during last two decades. Several kinds of rotating electrical generators exist for several applications, including synchronous, induction and DC machines. Doubly Fed Induction Generator is proposed as an alternative solution with respect to the cost of such a system. However, a bigger emphasis in the repo...
متن کاملCryptic preference for MHC-dissimilar females in male red junglefowl, Gallus gallus.
An increasing number of studies test the idea that females increase offspring fitness by biasing fertilization in favour of genetically compatible partners; however, few have investigated or controlled for corresponding preferences in males. Here, we experimentally test whether male red junglefowl, Gallus gallus, prefer genetically compatible females, measured by similarity at the major histoco...
