Real-time electromagnetic transient simulators are important tools in the design stage of new control and protection systems for\npower systems. Real-time simulators are used to test and stress new devices under similar conditions that the device will deal with\nin a real network with the purpose of finding errors and bugs in the design. The computation of an electromagnetic transient is\ncomplex and computationally demanding, due to features such as the speed of the phenomenon, the size of the network, and the\npresence of time variant and nonlinear elements in the network. In this work, the development of a SoC based real-time and also\noffline electromagnetic transient simulator is presented. In the design, the required performance is met from two sides, (a) using a\ntechnique to split the power system into smaller subsystems, which allows parallelizing the algorithm, and (b) with specialized and\nparallel hardware designed to boost the solution flow.The results of this work have shown that for the proposed case studies, based\non a balanced distribution of the node of subsystems, the proposed approach has decreased the total simulation time by up to 99\ntimes compared with the classical approach running on a single high performance 32-bit embedded processor ARM-Cortex A9.
