Abstract

The invention provides a multi-pole coordinated energy saving device of a distributed type power distribution network. The coordinated energy saving device comprises a data acquisition device, a data integration device and a data monitoring device, which are connected in sequence; the problem of reactive power loss, caused by the fact that reactive power compensation of the power distribution network is not enough, is effectively solved; smooth compensation can be realized by adopting flexible and dynamic reactive power adjusting equipment; the compensation efficiency is high and the compensation degree is accurate; the power grid loss is reduced to the greatest extent; a reactive power compensation device is more stable in a reactive power compensation process and the service life of the reactive power compensation device is prolonged; harmonic pollution in the power distribution network can be effectively solved and normal and reliable operation of a power grid is guaranteed; an automation level of the power distribution network is improved; various devices automatically work and manual intervention can be reduced in an operation process of the power distribution network and the labor intensity of technicians is alleviated; furthermore, various parameters in a power grid operation process can also be collected by the coordinated energy saving device, and overhauling work of the technicians is facilitated.

Description

technical field [0001] The invention relates to the field of distribution networks, in particular to a multi-pole coordinated energy-saving device and an energy-saving method for a distributed distribution network. Background technique [0002] The power grid is an important transmission channel for electric energy, and the energy saving and loss reduction of the power grid itself is an important part of my country's energy saving work. At present, the weakness of distribution network is one of the problems that need to be solved urgently in the structure of my country's power grid. Since the distribution network has many points and a wide area, the line structure is complex, and the loss is relatively large, accounting for more than 50% of the power grid loss, its energy-saving space is obvious. [0003] The energy consumption of the distribution network is mainly concentrated on the transmission line and the user demand side. In the distribution network below 10KV, especi...
