AUTOMATIC SUBNETTING METHOD FOR ELECTROMAGNETIC TRANSIENT GRID SIMULATION AND COMPUTER STORAGE MEDIUM

摘要

An automatic subnetting method for electromagnetic transient grid simulation and a computer storage medium, comprising automatic subnetting without specifying the number of subnets and automatic subnetting with a specified number of subnets. The parallel processing technique is applied in the power system electromagnetic transient simulation, being able to improve the simulating speed, satisfying the requirements of real-time and super-real-time simulation of a large-scale power system for the computing speed. By taking the nodes for the communication between networks as boundary points of the subnets, the whole power system simulation network is naturally divided into subnets, and the simulation step size of different networks is determined according to the precision requirements. In this automatic subnetting method, a decoupling element is not needed for the network division, and the network division is simple, clear, highly versatile, and fast in subnetting speed, being able to perform real-time and super-real-time simulation of VSC precise model-containing electromagnetic transient subnets having different rates and different step sizes in parallel.
