Abstract

Abstract: The problem of algebraic loop is common in Simulink simulation. The existence of algebraic loop will reduce the speed and accuracy of simulation, and even lead to errors in simulation results. Taking the simulation of synchronous generator as an example, the problem of algebraic loop and its elimination method in Simulink simulation are discussed. Starting from the analysis of the basic equations of synchronous generator, the cause of algebraic loop in simulation is discussed, the influence of the algebraic loop on the system simulation is pointed out, using disassembly method and transformation method, focusing on eliminating the algebraic loop, the system simulation results after eliminating the algebraic loop by using several methods are compared and analyzed, from the aspects of simulation time and simulation accuracy. The results show that the simulation speed of the system is obviously improved after the algebraic loop is eliminated, and the transformation method has a significant advantage over the disassembly method in the dynamic simulation accuracy of the system.
