Embodiment 1

[0044] The embodiment of the present invention provides an analysis method for reducing line loss, which can be applied to a 10kV high-voltage power transmission line. Such as figure 1 As shown, the method includes the following steps:

[0045] S1: Get the current time zone.

[0046] Since people’s work and rest time will cause the active power and reactive power of the power transmission line to change regularly in different time sections, the line loss in different time sections also changes regularly, so you can pre-calculate the daily The line loss changes in different time segments are used as a reference for line loss analysis of circuit transmission lines.

[0047] The specific statistical method can be based on the area corresponding to the power transmission line (such as an urban area or a town) as the statistical target, and the line loss changes in different time segments can be recorded and counted separately in several days.

[0048] As a preferred solution, the continu...

Embodiment 2

[0072] The embodiment of the present invention also provides an analysis system for reducing line loss, which can be applied to a 10kV high-voltage power transmission line. Such as Figure 5 As shown, the system includes a time section module 51, a compensation module 52, a line loss module 53, and an adjustment module 54.

[0073] Among them, the time zone module 51 is used to obtain the current time zone. Since people’s work and rest time will cause the active power and reactive power of the power transmission line to change regularly in different time sections, the line loss in different time sections also changes regularly, so you can pre-calculate the daily The line loss changes in different time segments are used as a reference for line loss analysis of circuit transmission lines.

[0074] The specific statistical method can be based on the area corresponding to the power transmission line (such as an urban area or a town) as the statistical target, and the line loss change...

Abstract

The invention provides an analysis method and system for lowering line loss, and relates to the technical field of power transmission. The technical problem that the existing effect of lowering the line loss is bad is solved. The method comprises the following steps: acquiring the current time range; generating reactive compensation amount according to the current time range; acquiring the line loss data of a power transmission line; and adjusting the reactive compensation amount according to the line loss data.

Description

Technical field [0001] The present invention relates to the field of power transmission technology, in particular to an analysis method and system for reducing line loss. Background technique [0002] As the power grid continues to grow, the power loss will also increase, and the workload of line loss analysis and management is also increasing, and its importance is becoming more and more obvious. During the operation of the power grid, the calculation and analysis of power and line loss indicators can assist, make decisions, and support the production and management of power enterprises, grasp the operation of equipment in a timely manner, and help managers understand the line loss, transformation loss, load, power quality, etc. The operating parameters provide the basis for future planning and technological transformation of the power grid, and realize the loss reduction and energy saving of the power grid. [0003] The line loss rate is the main economic and technical indicator...
