Line loss rate is the percentage of line loss in power supply, which is a
comprehensive technical and economic index reflecting the planning and design of
power grid, technical equipment and economic operation level. The power network
line loss is composed of three parts: fixed loss, variable loss and other loss. To reduce
the line loss of power network, we should find out the existing problems from the
aspects of economic production management, reasonable operation management and
scientific dispatching management, and take effective measures to reduce the line loss
to a reasonable range.
