A kind of intelligent substation on-line operation monitors and remote maintenance systemTechnical field
The utility model relates to a kind of intelligent substation on-line operation and monitors and remote maintenance system, belongs to power engineering application.
Background technology
In current electric power system, microcomputer-based intelligent equipment uses in a large number, particularly based on the relay protection device, failure wave-recording equipment, safety control device, stability contorting equipment, measuring power angle equipment etc. of microcomputer, these secondary devices are independent operating substantially in electrical network, lack the integrated managements such as integrated, the data analysis of information, early warning and utilize; The achievement that correlation technique development obtains is not made full use of yet.Along with construction and the development of computer network in transformer substation construction of intelligent substation, traditional single collection of secondary device information, low to aspect information flowrates such as transformer station's maintenances in the distance, electrical network O&M somewhat expensive, operation management difficulty, fails the advantage after embodying intelligent substation digitlization completely.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of intelligent substation on-line operation to monitor and remote maintenance system, and this system can realize the long-range intelligent substation on-line operation to each substation secondary device information, automatic monitoring, failure diagnosis, relaying protection distant place controlling functions and monitor and remote maintenance.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of intelligent substation on-line operation monitors and remote maintenance system, and this system comprises secondary device information collection module, input interface, relaying protection distant place control module, remote auto monitoring module, Analysis on Fault Diagnosis module, communication module and CPU; Described secondary device information collection module is provided with input interface; Described secondary device information collection module respectively with relaying protection distant place control module, remote auto monitoring module, Analysis on Fault Diagnosis model calling, described remote auto monitors and Analysis on Fault Diagnosis module is connected with CPU respectively by communication module.
Described remote auto monitoring module is sent to CPU by the detection data of setting cycle to secondary device through communication module.
The detection data of described Analysis on Fault Diagnosis module to secondary device are sent to CPU through communication module.
The beneficial effects of the utility model:
Intelligent substation on-line operation of the present utility model monitors and remote maintenance system can realize the supervision of the long-range intelligent substation on-line operation to each substation secondary device information, automatic monitoring, failure diagnosis, relaying protection distant place controlling functions and remote maintenance.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of intelligent substation on-line operation monitors and remote maintenance system, and this system comprises secondary device information collection module, input interface, relaying protection distant place control module, remote auto monitoring module, Analysis on Fault Diagnosis module, communication module and CPU; Described secondary device information collection module is provided with input interface; Described secondary device information collection module respectively with relaying protection distant place control module, remote auto monitoring module, Analysis on Fault Diagnosis model calling, described remote auto monitors and Analysis on Fault Diagnosis module is connected with CPU respectively by communication module.
Described remote auto monitoring module is sent to CPU by the detection data of setting cycle to secondary device through communication module.
The detection data of described Analysis on Fault Diagnosis module to secondary device are sent to CPU through communication module.
When using this system, first complete secondary device by secondary device information collection module and access native system with Standards Code by input interface, through communication module, CPU is sent to by remote auto monitoring module formation detection data to the secondary device information that secondary device information collection module obtains; Through communication module, CPU is sent to by Analysis on Fault Diagnosis module to the fault-detection data that secondary device information collection module obtains simultaneously; The distant place that the relaying protection data of secondary device information collection module acquisition complete protective relaying device through relaying protection distant place control module is controlled.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
