Theoretical line loss calculation is the basis of line loss analysis and decision-making in loss reduction. Due to technical constraints in the past, traditional theoretical line loss calculation method uses a large number of simplified calculations. This paper proposes a new online method of line loss calculation in distribution networks which is based on PQU (active power, reactive power and voltage) load curves. The proposed method has a large amount of data operation and thus can accurately reflect the load variation with time. Based on a new kind of metrical equipment and the proposed method, the assistant decision system for comprehensive power loss reduction of rural power network has been developed and has been tested on several rural power networks. The results show its convenience, accurate calculation and high efficiency.

Theoretical line loss calculation is the basis of making line loss analysis and loss-reduction decision. Due to technical constraints in the past, traditional algorithms on theoretical line loss calculation used a large number of simplified calculations. This paper proposes a new online method of line loss calculation in distribution networks which is based on PQU (active power, reactive power and voltage) load curves. Based on a new kind of metrical equipment and the proposed method, the power loss calculation system has been developed and has been tested on several rural power networks. The results prove that the method improves the assumptions of traditional algorithms and calculation precision.
