Resumo

The control of the compensation mode of the capacitive currents arising in the location of a single-phase earth fault is considered based on the measured parameters of the zero-sequence circuit of the distribution electric network. A brief description of the of the distribution networks with compensation of the capacitive current is given. The drawbacks of the existing methods and automatic adjustment tools of the arc-suppression coils are specified. The necessity of developing a method for determining the parameters of the network zero-sequence circuit without any drawbacks of the known methods of compensation adjustment is substantiated. The method of estimation of the parameters of the network zero-sequence circuit is described. The proposed method is investigated on the basis of circuit models and in the conditions of the existing distribution network. The results of investigations confirm that the proposed method of estimation is viable and has satisfactory metrological characteristics.
