Remote rural network power distribution line reactive monitoring system

Abstract

The invention discloses a remote rural network power distribution line reactive monitoring system, which comprises a intelligent electric meter, a remote monitoring terminal, a data receiving-and-sending module, a server, a data storing and displaying module, wherein the remote monitoring terminal is connected to the intelligent electric meter for acquiring electrical parameter in an electric network line; the electrical parameter comprises three phase voltage, three phase electric current, an active power, a reactive power and a power factor data; the electrical parameter is sent to the server of a remote transformer substation through the data receiving-and-sending module; and the data storing and displaying module is connected to the server. With the remote rural network power distribution line reactive monitoring system, the method is simple and effective; and reactive power remote monitoring of the electric network can be realized.

Description

technical field [0001] The invention relates to the field of monitoring in distribution networks, in particular to a reactive power monitoring system for remote rural power distribution lines. Background technique [0002] In recent years, with the improvement of people's living standards in rural areas and the adjustment of economic structure, the scale of rural power grids has expanded rapidly, and the electricity consumption in rural areas has increased significantly. At the same time, the requirements for power quality and electricity economy have also continued to increase. Due to the characteristics of scattered structure, long lines, many branches, scattered and uneven load, low load power factor, and high line loss rate, the rural power grid has generally low power factor. At the same time, due to the implementation of national preferential policies such as home appliances going to the countryside, old appliances for new ones, and the background of rising gas and coa...

Not only caused a large energy loss, but also produced economic benefits that cannot be ignored

[0003] In view of the low power factor of the distribution lines in the current rural power grid, the electric power departments in many areas are unable to conduct reasonable monitoring and management of the power parameters of the distribution lines, resulting in the inability to carry out effective and in-depth development of line reactive power compensation measures, making the rural Low power factor of power distribution line
