METHOD FOR DETERMINING CIRCUIT LOCATION IN ELECTRICAL SYSTEM Russian patent published in 2017 - IPC G01R31/08 H02H3/40 

FIELD: electricity.

SUBSTANCE: allocate two subsystems, which contacts at the place of closure. For the first subsystem make the transformative model, and for the second - simulative model. Inputs of converter model correspond to the inputs of the first subsystem, and the output - to the place of the intended closure. The inputs of the simulation model are divided into basic, corresponding inputs of the second subsystem, and additional corresponding to the place of the intended closure. The role of the transformational model is to form an intended circuit voltage space of continuous voltages and currents, obtained for the inputs of the first sub-model. A simulation model is activated by acting on its main input by continuous input voltages of the second sub-models. An additional input is affected by the output signals of the converter model. The reaction of the simulation model is determined only at the main inputs. There are currents, which are created by the impacts on all the inputs of the model. At the final stage determine the difference between the continuous currents in the main inputs, obtained from the observed currents and the model reaction. The level of difference currents carries information on whether the assumption is made correctly on the place of damage. The zero level indicates the coincidence of the real space with the expected.

EFFECT: enlarging functional capabilities of the method.
