Calculation of voltage dips in a 110 kV network
Original language description
The paper deals with the calculation of number and severity of voltage dips and the comparison of results with outcome of voltage dip monitoring. Method of fault positions is used. The remaining voltage is calculated for faults in each fault position. The computation was performed for all kind of faults and different failure rates of particular lines. Knowing the network parameters and the failure statistics of the network, the number of dips and distribution of remaining voltages can be estimated. Themethod of fault positions is applied to the real 110 kV grid. The expected number of dips and distribution of remaining voltage in the substation, and exposed area for this substation are calculated. The results are compared with the outcome of the voltage dip monitoring. The comparison shows a good correspondence in general.
