METHOD OF ACCOUNTING sag WIRE THREE-PHASE POWER LINES IN three-wire it into line with the electrical load

摘要

1. A method of accounting sag wire three-phase three-wire transmission line in its agreement with the electrical load, consisting in that the initial information about voltages and currents in the line via the interface device or sensors is supplied to the processor, wherein the processor checked refined matching conditions three-phase three-wire transmission line to an electrical load for each wire transmission line, which may vary due to increase or decrease the margin of seasonal ones perature, the formation of ice on the wires, which entails a change in sag wires, and hence the change in the primary line parameters based on which the obtained secondary line parameters and determine the conditions matching the three-phase three-wire transmission line to an electrical load, sag wireline proposed to estimate rangefinders, located throughout the length of the transmission line, the measured value of the arrows sag wire is transferred to the computer processor, which spe lysed program defining primary and secondary parameters of the three-phase three-wire transmission line, allows for boom size slack wires and refines the values ​​of the currents and voltages, called reference, which correspond to the currents and voltages coherent three-phase three-wire transmission line, then as a result of comparing the actual and reference values ​​of the load resistors , the stress at the end of line or currents flowing in the load control signals are generated for The correction
