Embodiment 1

[0032] Embodiment 1: Referring to the accompanying drawings, a reactive power flow optimization scheduling method for a distribution network includes the following steps:

[0033] a) Set up a reactive power compensation device C with multi-level adjustable capacity in the load center n of the main line of the distribution network, and regard it as a reactive power source; At nodes 1, 2, ..., n-1, n, an electrical data collector with wireless data communication function is installed to collect the voltage U of nodes 1, 2, ..., n-1, n i , active load P i , reactive load Q i , Active power P flowing to the next node i，i+1 and reactive power Q i，i+1 ;

[0034] b) Starting from the substation 1, calculate the resistance value R between the nodes 1, 2, ..., n-1, n in sections i，i+1 and reactance value X i，i+1 :

[0035] R i，i+1 = r i，i+1 L i，i+1 (1)

[0036] x i，i+1 =x i，i+1 L i，i+1 (2)

[0037] where r i，i+1 、x i，...

Abstract

This invention relates to a power dispatch method especially to a reactive tide dispatch method to distribution networks, which sets a reactive compensation device with the volume adjusted in many stages at the trunk load center of the distribution networks, sets an electric data collector with radio data communication function at each node [1, 2,apostrophe, n-1, n]to collect voltage U1, active load Pi, reactive load Qi, the active power Pi, i+1 and reactive power Qi, i+1 flowing to the next node, computes the total active power loss value, tries to move the reactive dividing line point to its adjacent node [j+1 ] from the initial reactive dividing line point, computes the total active power loss value at the new reactive dividing line point to regulate the output of the reactive compensation device.

Description

technical field [0001] The invention belongs to a distribution network electric power dispatching method, in particular to a method for carrying out reactive power flow dispatching on a rural distribution network. Background technique [0002] At present, my country's 10kv and 380v power grids, especially rural power grids, have not carried out optimal scheduling of reactive power flow, so the power grid line loss is high and the voltage quality at the user end is poor. Contents of the invention [0003] The object of the present invention is to provide a reactive power flow optimization dispatching method of distribution network to reduce loss and improve power supply quality of power network. [0004] The technical solution of the present invention is: a reactive power flow optimization scheduling method of distribution network, comprising the following steps: [0005] a) Set up a reactive power compensation device with multi-level adjustable capacity in the load center...
