碩士 === 崑山科技大學 === 電子工程研究所 === 107 === An Industrial Network Example is used to calculate the load flow by PowerFactory software. AC short-circuit protection uses the variation ”Number of parallel motors” with all ten parallel LV motors considered. After calculating the short-circuit current on any busbar of the AC network, the tripping time of the different relays are displayed in the corresponding result boxes. Through the powerful functions of DIgSILENT PowerFactory, the normal operation of the industrial network is very important. The over-current protection simulation analysis is for the research and analysis of the reliability of the grid circuit relay protection, which is of great significance to the safe operation of the grid.
