Techniczne i ekonomiczne aspekty zastosowania kaskady podsynchronicznej do regulacji wydajności sprężarki

The paper presents "Borynia" mine, where due to threat of methane the underground compressed air piping is supplied from central compressor station. Any change in the compressed air demand requires regulation of compressor work parameters. One of the possible solutions is the use of undersynchronous cascade for regulation of air compressor output. The paper on the basis of compressor TK-16 modernization, where such a way of rotation regulation has been applied, describes the premises of modernization, course of action, technical aspects and planed economic results of this solution. Final conclusions try to sum up obtained results of modernization of synchronic engine 6kV with 1800 kW output after installation of undersynchronous cascade.
