This paper describes a simulation method which allows stochastic assessment of voltage dips and short interruptions that may be expected at a given node of an electrical power network due to faulu occurring in it. Different types of faulu, symmetrical and asymmetrical, were takem into account. The symmetrical component approach was applied. Voltage dips are characterised by voltage symmetrical component vectors. The Monte Carlo method was applied, which allows getting frequency of a given voltage dips and short interruptions. Evaluating such characteristics is needed for assessing compatibility between loads and the supply network. The methodology has Been used to draw up a simulation tool by means of LABVIEW programme. The paper presents the results of simulation performed for a given electrical transmission and distribution network and discusses them.
