Abstract: The domestic electromagnetic transient（EMT） simulation platform has the problems of small user base, difficulty in promotion, and difficulty in serving engineering. It is urgent to find a suitable research direction to improve the simulation performance. With the gradual development of China’s power grid in the direction of large scale, high complexity and power electronics, the efficiency of current simulation platforms is relatively low. In addition, there is still space for the improvement in the software kernel, underlying openness, and the ability to interact with hardware objects of the current simulation platforms, and the ease of use of the platform can be further optimized. This paper summarizes the current modeling methods of the modular power electronic equipment, puts forward the forward-looking direction of simulation technology, and summarizes a generalized acceleration simulation framework that can effectively improve simulation efficiency. Finally, specific suggestions on the ease-ofuse optimization of domestic platforms are put forward, and the technical research directions are pointed out.
