Background

The network loss or line loss refers to the power loss dissipated in the form of heat energy in the electric energy transmission process, namely the active power consumed by the resistance and the conductance; the loss rate is a main economic and technical index comprehensively reflecting the planning design, production operation and operation management level of the power grid; the line loss of the power grid mainly comprises variable loss, fixed loss and management loss. Variable loss refers to the amount of power dissipated across the power line and power transformer resistances, which is proportional to the square of the transmitted power (or current). The fixed loss refers to loss generated on equivalent parallel conductance of a power line and a transformer, and mainly comprises iron loss of the power transformer, insulation medium loss of a power cable and a capacitor, leakage loss of an insulator and the like for a power distribution network. The fixed loss and the variable loss can be calculated by theory, so the fixed loss and the variable loss are often called theoretical line loss. The management loss refers to a portion of the line loss power minus the theoretical line loss.
