Abstract


The paper presents the results of load modelling at low voltage level of transformer station (TS) 10/0.4 kV/kV supplying predominantly residential load. Necessary data are obtained from recording device and measuring information system for continuous measurements permanently installed in concerned distribution network. Identified parameters of static exponential load model are classified according to day periods and days of the week, and statistically analysed in order to obtain reliable parameter estimates. These are compared with literature data for the same, residential load class. Possibilities for further application of described load modelling procedure are listed.
