EMTP 기반 지중송전계통 해석용 시뮬레이터 개발 및 응용

Development and Application of EMTP based Simulator for Analysis of Underground Power Cable Systems

In this paper, new simulator based on EMTP was introduced for simulation of underground power cable system. The newly developed simulator was named as Power Cable Simulator(PCS), and it can simulate the various normal conditions including sheath circulating current. It is also easier to use than conventional software, such as EMTP and CabSim, because all the data for calculating the cable parameters are stored in a database(DB) within a PCS. In addition, the accuracy of PCS is also proved through the comparison between the calculation and simulation of sheath current.
