Embodiment Construction

[0019] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the power grid fault accident processing method, the processing method includes the following steps:

[0021] Step 1. Determine the fault accident processing sequence according to the fault accident conclusion. To determine the fault accident processing sequence needs to be judged according to the working conditions of the fault equipment before the power outage. Even better, when the load line fails, if it causes the upper-level equipment to lose power, then The processing sequence is, first pull the load switch, then restore, and finally isolate the load switch;

[0022] Step 2. Determine the isolation equipment according to the fault handling sequence, and completely cut off the connection between the faulty equipment and the non-faulty equipment. Even better, when the bus fa...

Abstract

The invention discloses a grid fault accident management method. The management method comprises the following steps: step 1, determining a fault accident management sequence according to a fault accident conclusion; step 2, determining isolation equipment according to the fault accident management sequence; step 3, determining initial recovery equipment; step 4, forming an island to be recovered; step 5, selecting single equipment power transmission rules; step 6, selecting an optimal power transmission scheme; and step 7, transferring power to equipment, and finishing the fault accident management. An effective solution can be provided for fault accident reasons, a recovery scheme is intelligently or manually generated, the accident management reliability is ensured, and electric power can be conveniently and quickly recovered.

Description

technical field [0001] The invention relates to a method for handling grid failure accidents. Background technique [0002] The power system has the characteristics of a hierarchical structure, that is, the power system is composed of stations and lines, and the stations are composed of switches, switches, busbars, transformers, generators, capacitors, load lines and other equipment. The network topology is formed by the connection relationship between the plants and stations, and the network topology is formed by the connection relationship between switches and switches between electrical equipment. In the prior art, power system accident handling is based on the text of regulations and abstract dispatching experience, which is time-consuming and laborious, and the results are not accurate enough. After an accident, the on-duty personnel dispatched by the substation or the lower level will report the protection action and switch tripping by telephone, and go to the trippin...
