Abstract: | The paper considers the issue of calculating of the wires complex impedances and resistances of the re-grounding connections in a three-phase distribution network. It is based on measurement data of the effective values of voltages and currents, as well as phase shifts between them, performed simultaneously by the electricity metering system at the start of the network and at each of its subscribers. An algorithm (method) of solving the above problem is presented for the case when in the distribution network the resistances of the phase and neutral wires within each inter-subscriber section and of all re-grounding connections are the same. The proposed algorithm (method) is based on serial (iterative) calculation and verification of the equality of the current through the grounding connection of the electrical energy source and the total current of all re-grounding connections in the distribution network. The correctness of the calculated expressions of the proposed algorithm (method) is confirmed by the presented calculation example for the simulated distribution network. The results obtained can be useful in organizing diagnostics of the functional state of re-grounding connections and sections of the main line, as well as in calculations and monitoring of electricity losses performed by an automated metering system operating in a distribution network with re-grounding connections |
