Construction and Application of Electromagnetic Transient Computing Platform

Aiming at the current situation that the existing electromagnetic transient calculation software has high requirement for experience and can not meet the timeliness requirement of power grid fault analysis, an Electromagnetic Transient Calculation Platform (abbreviated as the ETCP) is constructed through the secondary development of ATP-EMTP software. Based on the ETCP, several over-voltage calculation and risk assessment work, simulation analysis of on-load voltage regulation and capacitance regulation of distribution transformer, feasibility analysis of series reactor of main transformer neutral point, simulation calculation of low frequency oscillation of the PT have been carried out, which verifies the effectiveness and practicability of the ETCP.
