Influence of distributed generation systems in the distribution systems can increase the level of short-circuit current. The effectiveness of distributed generation systems is affected by the size, location, type of distributed generation systems technology, and the methods of connecting to distribution systems. Wind turbine system is the examples of distributed generation source. Not only does...

The object of research is the processes that affect mechanical characteristics steels after treatment melts with silicon-free complex master alloys according to existing technologies. One most problematic places negative effect silicon on weldability low-alloy steel, sharply increasing heterogeneity welds in sulfur and phosphorus their susceptibility hot cracks. cyclic strength welded joints de...
