| Abstract: | At design of electric control system for the compressor completed for large sized air separation plant many factors shall be considered, and they mainly include the selection of motor start mode on basis of grid conditions and run curve of the compressors set, selection of electric main primary wiring, rational setting of interlocked control condition, treatment of urgent shutdown signal and power-failure safety principle for the design, which is a system project. A safe, reliable and economic design scheme of electric control system is summarized on basis of several years＇project design and site debugging experiences. |
