Description

Grid fault analytical method
Technical field
The present invention relates to grid fault analytical method.
Background technology
Electric system has the feature of hierarchical structure, and namely electric system is made up of plant stand, circuit, and plant stand is made up of equipment such as switch, disconnecting link, bus, transformer, generator, capacitor, charge circuit.Form network topology by line connecting relation between plant stand, between electrical equipment, formed plant stand topology with switch and plug-in strip annexation.In prior art, power system device failure analysis methods is according to code text and abstract scheduling experience, and waste time and energy, result is not accurate enough.After having an accident, operator on duty's reporting by telephone protection act situation of being dispatched by transformer station or subordinate and switch trip situation, and manually check equipment failure situation to trip device place.During accident settlement, be also according to power grid accident after the method for operation and the topological structure and accident treatment code etc. of electrical network, the fault recovery scheme that engineer is feasible, and the grid switching operation being completed accident treatment by the mode that straighforward operation or phone are issued a notice.Visible, the mode of this manual analysis and accident settlement, with power network safety operation and prevent 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 grid fault analytical method, effectively can analyze the faulty equipment in electric system, accurate failure judgement device type, proposes effective solve scheme, and fast and easy recovers electric power.
In order to achieve the above object, the present invention is achieved through the following technical solutions: grid fault analytical method, is characterized in,
Above-mentioned method comprises following steps;
Step 1, acquisition power failure equipments information;
Step 2, acquisition switch motion information;
Step 3, acquisition protection act information;
The method of operation before and after step 4, acquisition fault;
Step 5, the information obtained according to step 1-4, must be out of order conclusion.
Obtain power failure equipments information in above-mentioned step 1 to refer to, enumerate power failure equipments, and describe the running status of electrical network when having a power failure generation.
Need power equipment to classify before obtaining power failure equipments information in above-mentioned step 1, be divided into: switchblade knife equipment, equipment except switchblade knife equipment.
Obtain switch motion information in above-mentioned step 2 to refer to, judge the repeatedly action of switch, the repeatedly action of switch is integrated into a switch motion information.
Outage analysis is carried out after obtaining switch motion information in above-mentioned step 2.
Obtain protection act information in above-mentioned step 3 to refer to, judgment device whether trigger protection signal, obtains protection act model.
Obtain the method for operation before and after fault in above-mentioned step 4 to refer to, judge the power supply direction equipment of this equipment, obtain dead electricity model.
Fault conclusion is obtained according to protection act model and dead electricity model in above-mentioned step 5.
Grid fault analytical method of the present invention compared with prior art has the following advantages: the failure message being obtained equipment by step-by-step analysis, and get rid of suspicious factors, accurate judgment device failure cause, proposes effective solve scheme, and fast and easy recovers electric power.
Accompanying drawing explanation
Fig. 1 is the method flow diagram of grid fault analytical method of the present invention.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
Grid fault analytical method, method comprises following steps;
Step 1, power equipment to be classified, be divided into: switchblade knife equipment, equipment except switchblade knife equipment, obtain power failure equipments information, enumerate power failure equipments, and describe the running status of electrical network when occurring of having a power failure;
Step 2, acquisition switch motion information, judge the repeatedly action of switch, the repeatedly action of switch be integrated into a switch motion information, carry out outage analysis afterwards;
Step 3, obtain protection act information, judgment device whether trigger protection signal, obtains protection act model;
The method of operation before and after step 4, acquisition fault, judges the power supply direction equipment of this equipment, obtains dead electricity model;
Step 5, the protection act model obtained according to step 1-4 and dead electricity model, must be out of order conclusion.
Although content of the present invention has 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 amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
