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
The present invention relates to electric network fault accident treatment method.
Background technology
Electric power system has the characteristics of hierarchical structure, i.e. electric power system is made up of factory station, circuit, and factory is made up of equipment such as switch, disconnecting link, bus, transformer, generator, capacitor, load circuits at the station.Factory constitutes network topology by line connecting relation between the station, constitutes factory's station topology with switch and plug-in strip annexation between the electric equipment.In the prior art, power system accident is handled according to rules text and abstract scheduling experience, wastes time and energy, and the result is not accurate enough.After having an accident, report protection action situation and switch trip situation by operator on duty's phone of transformer station or subordinate's scheduling, and manually check the equipment fault situation to the trip device place.During the processing accident, also be according to the topological structure of the operational mode behind the power grid accident and electrical network and accident treatment rules etc., manually design feasible fault recovery scheme, and finish the grid switching operation of accident treatment by the mode that straighforward operation or phone are issued a notice.As seen, the mode of this manual analysis and processing accident is with power network safety operation and prevent that the requirement of large-area power-cuts from being incompatible.
Summary of the invention
The object of the present invention is to provide a kind of electric network fault accident treatment method, can guarantee the reliability of accident treatment, convenient fast quick-recovery electric power.
In order to achieve the above object, the present invention is achieved through the following technical solutions: electric network fault accident treatment method is characterized in that described processing method comprises following steps:
Step 1, determine the failure accident processing sequence according to the failure accident conclusion;
Step 2, determine xegregating unit according to the failure accident processing sequence;
Step 3, determine initial restorer;
Step 4, formation island to be recovered;
Step 5, choose individual equipment and send electricity rule;
Step 6, selection the best are sent electric scheme;
Step 7, send electricity to equipment, failure accident disposes.
Determine the failure accident processing sequence to judge according to the operating mode before the power failure of faulty equipment in the above-mentioned step 1.
Determine in the above-mentioned step 2 that xegregating unit refers to contacting fully between faulty equipment and the non-faulty equipment cut off.
Determine all power equipments that need to be connected with this equipment before the initial restorer to disconnect in the above-mentioned step 3.
Individual equipment send electric rule to comprise in the above-mentioned step 5: bus send to stop using before the electricity and autotomys, and send to use behind the electricity and autotomys;
Circuit send the reclosing of stopping using before the electricity, uses reclosing after sending electricity.
Electric network fault accident treatment method of the present invention compared with prior art has the following advantages: the present invention can be at the failure accident reason, propose effectively to solve countermeasure, intelligent or manually generate recovery scheme, guarantee the reliability of accident treatment, convenient fast quick-recovery electric power.
Description of drawings
Fig. 1 is the method flow diagram of electric network fault accident treatment method of the present invention.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferable specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, electric network fault accident treatment method, processing method comprises following steps:
Step 1, determine the failure accident processing sequence according to the failure accident conclusion, determine the failure accident processing sequence to judge according to the operating mode before the power failure of faulty equipment, better, when the load line fault, if it causes the higher level equipment dead electricity, processing sequence is so, draws back on-load switch earlier, recover then, isolate on-load switch at last;
Step 2, determine xegregating unit according to the failure accident processing sequence, contacting fully between faulty equipment and the non-faulty equipment cut off, better, when busbar fault, if fault bus has bus arranged side by side, and side by side bus is electriferous state, so during the handling failure bus, need pour on the bus arranged side by side the load line of fault bus is cold, carry out the isolation of bus then;
Step 3, determine initial restorer, all power equipments that will be connected with this equipment disconnect;
Step 4, formation island to be recovered;
Step 5, choose individual equipment and send electricity rule, individual equipment to send electric rule to comprise bus to send to stop using before the electricity and autotomy, send to use behind the electricity and autotomy; Circuit send the reclosing of stopping using before the electricity, uses reclosing after sending electricity;
Step 6, selection the best are sent electric scheme;
Step 7, send electricity to equipment, failure accident disposes.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
