Modelling and study of steady state analysis and fault parameters in 400 kV and 220kV buses of Indian North Eastern Regional Grid

摘要

The paper studies the load flow simulation studies of North Eastern Grid of India using PSS¿¿E, well-accepted and commercial software from SIEMENS. The studied system comprises of 143 buses of different voltage levels and transmission lines running over a length of 6445 km. 80% loading for all the lines has been assumed for this study. The results have been validated by solving the model using DIgSILENT, also commercially known as Power Factory and a satisfactory convergence in both of the result has been seen. Simulations have also been performed for various kinds of faults.
