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.
