“…In Figure 4, R is the line resistance. When a non-linear load is connected to the system, the three-phase currents I A , I B , I C, and neutral current In produce line loss in the line resistance R. The three-phase voltage, current, and phase angle information at measurement Point 2 is collected, and the original three-phase system is equivalently transformed to decompose the load measurement equivalent apparent power S e [24,25]. The equivalent system has the same line power losses as the actual distribution system, and Figure 4 shows a schematic diagram of the three-phase, four-wire low-voltage distribution system after introducing the equivalence.…”

“…1459. The IEEE Working Group is in the process of improving the IEEE 1459 standard considering the physical meaning of the measurement theory and reactive power definitions [24,25], but this does not affect the application of the IEEE 1459 standard in line loss calculations and line loss analyses, due to the fact that the line loss itself is caused by the current flowing through the line.…”

This study investigates the feasibility of utilizing the line loss power factor to assess the reactive, unbalanced, and harmonic line losses in low-voltage distribution networks and explores the method of calculating decoupled line loss values based on this factor. To achieve this objective, we establish preliminary definitions of single-phase and three-phase reactive, unbalanced, and harmonic line loss power factors, drawing upon the principles of electrical theory outlined in IEEE Standard 1459. These power factors serve as crucial indicators for evaluating the severity of line losses caused by reactive power, unbalance, and harmonic problems. Subsequently, the values of line loss attributed to reactive, unbalanced, and harmonic components are decoupled and quantified using the line loss power factor as a fundamental parameter. The effectiveness and accuracy of the proposed method were verified in Matlab simulation and physical experiments.
