Improving time integration scheme for fet analysis of power system angle stability
This paper presents improved algorithm for numerical analysis of power system angle stability achieved by improvement of the time integration when forming a local system of equations for power system finite elements (FE). Previously developed local system of equations of power system angle stability has been obtained using the generalized trapezoidal rule (ϑ - method). Improvement of accuracy was obtained by using Heun's method. Numerical solutions obtained using Heun’s method and using the generalized trapezoidal rule are compared to Electromagnetic Transients Program (EMTP). It has been shown that Heun’s method yields the results with much higher accuracy comparing to results obtained by generalized trapezoidal rule.
