Electrical power system modeling and simulation of large-scale industrial enterprise

The paper introduces models of major AC element of ETAP software, required data by different analysis modules, along with concepts and application of 3-D database including data versions, one line diagram and configuration on the basis of the importance of characteristics, modeling and analytical calculation of electrical power system in large-scale industrial enterprises. In terms of the practices of electrical power system modeling and simulation analysis in large-scale petrochemical enterprises, the paper specifically discusses the experiences to use ETAP. Comparison of power flow actual measurement data and ETAP load flow analytical result, along with the comparison of short-circuit hand calculation result and ETAP short-circuit calculated result, is provided at the end of the paper. The comparative result fully proves high efficiency, convenience and validity of ETAP software.
