Regional power grid line forced power-on auxiliary decision making system

Abstract

The invention discloses a regional power grid line forced power-on auxiliary decision making system which comprises a line information collecting module, a line information transmission module, a lineinformation identification module, a useless information removal module, a line information processing module, a line information decision-making module and a man-machine interaction interface display module. A regional power grid line forced power-on auxiliary decision-making method comprises the steps of s1, establishing a line information standing book, wherein the line information standing book comprises the full length of a line, stations connected, the line and cable relevant information, the short-circuit resistance of the main transformers of the stations connected and the short-circuit resistance of the main transformers which are in parallel operation with the main transformers of the stations connected, and other information including whether the line belongs to a line transformer group or not, and whether the line is a test operation line or not. The system and method are widely applied to accident treatment after tripping of a power grid line, and help a regional power grid dispatcher to decide whether to forcedly power on the tripped power grid line or not. If the forced power-on condition is met, a proper forced power-on terminal is recommended to the dispatcher, sothat the forced line power-on time can be remarkably shortened, and the forced line power-on efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching operation, in particular to an auxiliary decision-making system and method for forced transmission of regional power grid lines. Background technique [0002] The voltage level of the lines under the jurisdiction of the regional power grid is relatively high, and the impact range is wide after the trip. For substations powered by dual power sources, there is a risk of single power supply power supply after one of the lines trips. Power outages for users cause unnecessary economic losses and negative social impacts. [0003] After the line trips, the dispatcher needs to consider many factors when deciding whether to force the delivery, and needs to check the relevant data ledgers. These data ledgers are often scattered, and the checking process is time-consuming and laborious. After repeated deliberations by the dispatcher, when the dispatcher finally decides to force the delivery, ...

AI Technical Summary

Problems solved by technology

It usually takes a lot of time from the tripping of the line to the dispatcher's order to force transmission, which can easily cause untimely force transmission and the possibility of wrong force transmission, which increases the risk of power grid operation
