Automatic generation method for power supply transferring scheme in distribution network with substation voltage loss

Abstract

The invention provides an automatic generation method for power supply transferring scheme in distribution network with substation voltage loss. The method comprises the following steps: S1: basic data acquisition, a data interface is established with each major related system, related data information is acquired; S2: data processing and analysis, the data in S1 is combined to generate the powersupply transferring scheme for transferable distribution network lines, the 10kV bus series power supply scheme for nontransferable distribution network lines, load analysis of power supply transferring for the main substation and main network lines affiliated by the side distribution network lines, and influence analysis on important users by the substation voltage loss and plan support; S3: datadisplay in all directions.

Description

technical field [0001] The invention relates to the field of electric power systems, and more specifically, relates to an automatic generation method for a substation loss-of-voltage distribution network transfer power supply scheme. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, people's requirements for power supply services are also getting higher and higher. In the Pearl River Delta region, some severe weather conditions often occur, resulting in large-scale power outages on the power grid, especially when the main network line fails, often resulting in voltage loss in substations and short-term failure to transmit power in time. When the substation loses voltage and cannot transmit power for a short time, in order to realize the rapid restoration of power for users, it is generally necessary to transfer the power supply operation of the distribution network line with loss of voltage to realize th...

AI Technical Summary

Problems solved by technology

[0004] The above tasks need to spend a lot of time for the distribution network dispatcher when checking before the power supply is transferred, and it is time-consuming and laborious, and the accuracy is difficult to guarantee

Especially when the substation loses voltage, there are generally many feeder lines that need to be transferred to power supply, and it takes a lot of time, which leads to the inability to implement timely transfer of power supply, so that users still need to wait for a long time after the substation loses voltage. It takes time to restore power by switching power supply, which affects power supply reliability and user satisfaction, and leads to more power outage losses
