Embodiment

[0137] This patent uses the IEEE RBTS-BUS4 distribution network system as the test distribution network system, and its topology is as follows image 3 shown.

[0138] The power distribution system has a total of 7 feeders, 38 load nodes, 241 candidate locations for various terminals, 4,779 users, and a total average load of 24.58MW.

[0139] It can be found that if the general brute force algorithm is used to solve the solution, the result of the solution has 2 241 This would be a disaster of dimensionality. On the other hand, this model is therefore also very suitable for verifying the validity of the model proposed in this patent.

[0140] The relevant parameters used in this patent are as follows:

[0141] Table 1 Time class parameters

[0142]

[0143] Table 2 Price class parameters

[0144]

[0145] where R 1 ,R 2 with R 3 Unit electricity price for residential load, commercial load and industrial load respectively

[0146] Table 3 Fault class parameters

Abstract

A method for optimizing configuration of distribution network automation terminals, which is constructed based on logical operators, and specifically includes the following steps: Step 1: constructing a general term model of load outage time that only considers manual disconnectors; Step 2: constructing consideration Construction of the load outage time general model of the manual disconnector and fault indicator; Step 3: Build the load outage time general model considering both the manual disconnector, the fault indicator and the automatic disconnector.

Description

technical field [0001] The invention belongs to the field of power system planning, and in particular relates to an optimal configuration method for an automation terminal of a distribution network. Background technique [0002] With the continuous development of social economy, users have higher and higher requirements for the reliability of power supply of distribution network. By introducing various types of distribution network automation terminals, fault isolation can be quickly achieved, fault location can be accelerated, and load transfer can be performed to minimize power outage losses caused by permanent faults and user outage time, which is to improve the reliability of the distribution network. the most effective means. [0003] In the prior art, a patent document with the authorization announcement number of CN201611215510 discloses a method for optimizing the configuration of distribution network terminals. This patent conducts in-depth research on the installa...
