Abstract
The invention relates to an electric power equipment fault early-warning method which comprises the following steps of acquiring acting quantity information of a power grid in a fault occurrence time, namely switch information and protection action information; acquiring action information from a data acquiring and monitoring system and a circuit breaker, and obtaining fault occurrence time of each action node of a suspected faulted component; discriminating faulted equipment in the power grid in a real-time online manner and generating fault brief information; combining the switch information, the protection action information and the fault brief information by a transformer substation for forming transformer substation fault data information; receiving and analyzing uploaded fault data information by a scheduling center, performing real-time diagnosis on the fault equipment of the power grid according to a logical reasoning algorithm, and performing comparison checking on the diagnosis result and the fault diagnosis result of the transformer substation. The electric power equipment fault early-warning method has advantages of acquiring fault information in the power grid equipment in time, shortening accident processing time, ensuring safe and reliable operation of the power grid, ensuring high safety of power grid equipment and preventing abnormity of the power grid.
Description
Technical field
The present invention relates to grid equipment detection technique field, be specifically related to a kind of electrical equipment fault method for early warning.
Background technology
Along with China's power industry fast development, installed capacity in power grid quickly increases, and electrical network scale is with becoming to expanding, and also complicated therewith in structure, the method for operation is varied, and the warning message presenting to dispatcher also gets more and more. When electrical network is properly functioning, the warning information that power equipment produces also needs to artificial treatment; During electric network fault, hundreds of warning message can at short notice on deliver to regulation and control center, these warning messages can not be carried out Correct Analysis and process by regulation and control person in very short time, it is impossible to make full use of fault message find out fault occur region and equipment. So there is fault message difficult judgment in existing dispatching of power netwoks warning system, artificial treatment labor intensity is big, accident treatment efficiency is low, the shortcoming affecting power grid security, reliability service.
Summary of the invention
It is an object of the invention to provide a kind of electrical equipment fault method for early warning, it is possible to obtain the fault message of server timely, notify staff timely, shorten the accident treatment time, ensure power grid security reliability service.
For achieving the above object, present invention employs techniques below scheme:
A kind of electrical equipment fault method for early warning, comprises the following steps:
(1) by a large amount of warning messages produced before and after electric network fault are screened, it is thus achieved that namely the actuating quantity information in electric network fault moment switch and protection act information;
(2) action message from data acquisition, monitoring system and chopper is obtained, first gone out power supply interrupted district by breaker actuation condition adjudgement, again the element in power supply interrupted district is classified as suspected malfunctions element, by protecting the time scale information with chopper, obtain the fault time that each action node of suspected malfunctions element occurs;
(3) namely switch according to actuating quantity information, the differentiating in electrical network the equipment broken down and form fault bulletin information of protection act information and real-time online fault time;
(4) transformer station forms substation fault data message after switch, protection act information and fault bulletin informix being collected, and is sent to grid dispatching center monitoring system by dispatch data net;
(5) control centre's real-time reception resolve the fault data information that each transformer station uploads, adopts logical reasoning algorithm, real-time diagnosis electric network fault equipment, and check of being compared by the fault diagnosis result of diagnostic result Yu transformer station.
Further, described fault data information includes: data public information part, for recording the basic public information of described substation fault data; Data block information part, for recording the content of described substation fault Deta bearer.
As shown from the above technical solution, heretofore described electrical equipment fault method for early warning can obtain the fault message in grid equipment timely, notify staff timely, shorten the accident treatment time, ensure power grid security reliability service, thus ensure that the safety of grid equipment, it is to avoid electrical network generation abnormal conditions.

S3: namely switch according to actuating quantity information, the differentiating in electrical network the equipment broken down and form fault bulletin information of protection act information and real-time online fault time;
S4: transformer station forms substation fault data message after switch, protection act information and fault bulletin informix being collected, and is sent to grid dispatching center monitoring system by dispatch data net;
S5: control centre's real-time reception also resolves the fault data information that each transformer station uploads, adopts logical reasoning algorithm, real-time diagnosis electric network fault equipment, and check of being compared by the fault diagnosis result of diagnostic result Yu transformer station.
The present embodiment, described fault data information includes: data public information part, for recording the basic public information of described substation fault data; Data block information part, for recording the content of described substation fault Deta bearer.
Embodiment described above is only that the preferred embodiment of the present invention is described; not the scope of the present invention is defined; under the premise designing spirit without departing from the present invention; various deformation that technical scheme is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that claims of the present invention is determined.
