Embodiment Construction

[0035] The above and other technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0036] refer to figure 1 , the present invention provides a method for full stop and full rotation of a substation, which includes step S100, step S200 and step S300.

[0037] In step S100, the transferable load of the current substation and the load to be transferred of the current line are obtained. Here, the reason to obtain the transferable load of the current substation and the load to be transferred of the current line is because there are many lines in the substation. Under normal conditions, each line has a certain load, and correspondingly, there are A certain amount of transferable load. The transferable load of the substation is the sum of the transferable loads of many lin...

Abstract

The invention discloses a substation complete-shutdown and complete-transfer method. The substation complete-shutdown and complete-transfer method comprises the steps of: step 1, acquiring transferable load quantity of a current substation and load quantity to be transferred of a current line; step 2, judging magnitudes of the obtained transferable load quantity of the current substation and the obtained load quantity to be transferred of the current line, so as to transfer load of the current line; step 3, and transferring the load of the current line according to magnitudes of the transferable load quantity of other lines and the load quantity to be transferred of the current line, wherein a transfer equation is that x is equal to beta*Y / (1+alpha)<n>, x is the load quantity transferred to the other lines, Y is the transferable load quantity of the other lines, beta is an adjusting factor, alpha is a power supply margin of the other lines, and n is the year limit of a reserved margin of the other lines.

Description

technical field [0001] The invention relates to the technical field of substation control, and more specifically relates to a method for full stop and full rotation of a substation. Background technique [0002] In order to supply power to users safely, reliably, and economically, the power grid should have necessary capacity margins, appropriate load transfer capabilities, certain self-healing capabilities and emergency handling capabilities, and reasonable distributed power acceptance capabilities. [0003] Generally speaking, there are two reasons for the total shutdown of the substation: 1. The total shutdown of the substation caused by some equipment in the power grid, such as the complete shutdown of the substation caused by line faults and faults in the station; 2. The normal operation and maintenance of the power grid. , in order to ensure the safety of equipment and the personal safety of operation and maintenance personnel, the substation is completely shut down. ...
