Abstract

The power distribution systems of the Mass Transit Railway Corporation consist of loads having different voltage dependent characteristics. However, conventional loadflow methods are not adequate for accurate system study and for fast contingency study. A load modelling technique, in which each voltage dependent load is modelled by a Norton equivalent comprising of a 2×2 admittance matrix and a current vector, is introduced in this paper. Because this load model is always tangential to the actual load characteristics and a primitive nodal method can be employed, the proposed technique is easily programmed and converges rapidly. Advantages of the proposed technique will be further discussed with respect to the conventional loadflow methods with constant MVA loads.
