Embodiment 1

[0054] Such as figure 1 As shown, a method for batch transfer scheme analysis of distribution network feeders includes the following steps:

[0055] S1: Collect data information from the dispatching master station system: use the data transmission channel to obtain the power grid CIM model data of the main network dispatching automation system, the power grid CIM model data of the distribution network dispatching automation system, and splicing the main distribution network model data; The master model is integrated with the overall model CIM 总 ;

[0056] S2: Receive the power grid operation data of the main network dispatching automation system, the power grid operation data of the distribution network dispatching automation system, and store the maximum current I of batch transfer equipment and feeders max , to analyze the carrying capacity of the equipment on the other side in contact with the batch transfer scheme;

[0057] S3: Receive the grid CIM model data of the dis...

Embodiment 2

[0089] An analysis method for batch-transfer power supply scheme of distribution network feeder, comprising the following steps:

[0090] S1. The process of collecting data information from the dispatching master station system is: using the data transmission channel, respectively from the grid CIM model data of the main network dispatching automation system (1) and the grid CIM model data of the distribution network dispatching automation system (2), and In this system, the main distribution network model data is spliced ​​(3); the overall model CIM that realizes the integration of the main distribution model 总 , the system has the full model data of the power grid;

[0091] 1) The method of splicing (3) of the main distribution network model: model splicing of the distribution network feeder at the end of the main network system and the feeder data at the head end of the distribution network system. The identification rule of the main distribution network feeder is: substati...

Abstract

The invention provides a method for analyzing batch transfer schemes of distribution network feeder lines. The real-time nature of the analysis of the distribution network feeder involved; real-time synchronization of the data information required for the intelligent analysis of the feeder batch transfer scheme, which can ensure the accuracy of the intelligent analysis scheme when abnormal defects and accidents in the dispatching system require emergency analysis and processing; Not only can set the transfer-out device, but also can receive the transfer-out device provided by the system function of the source end by providing the control service mode. This method ensures the rapidity of system integration and application; Intelligent analysis of the whole process of feeder batch transfer scheme based on such data ensures the reliability of the analysis scheme.

Description

technical field [0001] The invention relates to the field of main distribution network management algorithms, and more specifically, relates to a method for analyzing batch transfer schemes of distribution network feeders. Background technique [0002] With the large scale of equipment under the jurisdiction of the regional power grid, the number of substations at all levels of voltage and the increase in the number of distribution and power supply lines, the real-time control system of the power grid is becoming more and more complex. And the more substations in the region, the more distribution network lines are supplying power to customers. [0003] In the daily power grid construction, it is necessary to cut off the power of the main grid operation lines and equipment, and continuously add substations and lines for economic development, so as to connect more loads; and a large number of grid operation equipment also need regular power outage maintenance work, in order to...
