Background technology

The arrival of and regional interconnected trend complicated along with the expansion of electric power networks, the behavior of transformer substation system also will become increasingly complex.The applicability of some original assumed conditions and simplified model all will be accepted further challenge and check.Enrich detailed field measurement data, especially fault or the data under the abnomal condition in the case, will have more and more significant values undoubtedly.They are not only the foundation of analyzing failure cause check relay protection action behavior, also for work about electric power person studies the real behavior of understanding complication system, find that its rule provides valuable data.

Along with advancing by leaps and bounds of singlechip technology, the use of high performance substation data harvester can further enlarge the quantity of information of electric system, improves reliability, accuracy, dirigibility, real-time and provides necessary advantage for sharing information resources.

Summary of the invention

The purpose of this utility model provides a kind of substation data acquisition and analysis device that utilizes current advanced person's embedded scm technology; its main task is the change procedure of the relevant system electric parameter after the big disturbance of record transformer station takes place and the action behavior of relay protection and automatic safety device; substation data is gathered and detailed analysis in real time, make it to adapt to better the needs of power system development.

Substation data acquisition and analysis device of the present utility model, it is characterized in that comprising core processor, respectively therewith the analogue collection module, switch acquisition module, non electrical quantity acquisition module, transducer signal input interface, touch-screen, USB interface, Ethernet interface, VGA interface, the GOOSE that are connected of core processor open into, described analogue collection module, switch acquisition module, non electrical quantity acquisition module are connected with voltage table, reometer, isolating switch, disconnector, the transformer of transformer station respectively.

Described core processor is ECN-I765.

Described transducer signal input interface unit is electronic mutual inductor signal input interface or conventional transducer signal input interface.

Described core processor is connected with analogue collection module, switch acquisition module, non electrical quantity acquisition module by the inner high speed bus.

The utility model mainly partly is made up of core processor, switch acquisition, analog acquisition, communication interface, display unit.Can support respectively electronic mutual inductor and conventional mutual inductor the input, can support the communication standard IEC61850 of transformer station of new generation, support comprehensively GOOSE open into.

The utility model is gathered the non electrical quantity states such as voltage, electric current, isolating switch and temperature of oil in transformer of transformer station in real time by the optical fiber interface of analogue collection module, switch acquisition module, non electrical quantity acquisition module or digital transformer substation.

The switch acquisition module functions have finish regularly start, manually boot, idle contact starts and low-frequency start, the high frequency of condition in starting starts, logout, frequency record under each condition of variable frequency starting.

The major function of analogue collection module has: finish manually boot, the collection of the analog quantity under the sudden change amount startup of condition in starting, overcurrent startup, overvoltage startup, under-voltage startup, the startup of negative phase-sequence overcurrent, the startup of zero sequence overcurrent, negative phase-sequence overvoltage startup, electric current variation entry condition.

The data that switch acquisition module and analogue collection module collect are passed to core processor by the inner high speed bus, after core processor is received real time data, put in order and preserve with file layout, and mutually and content such as fault localization, and these contents are shown on touch-screen according to the real time data failure judgement type of receiving, fault-time, failure line selection, choosing.The voltage and current that mainly is circuit, bus and transformer to transformer station is gathered automatically, is stored, action behaviors such as transformer station's failure message, protective relaying device, switch; And calculate the effective value of electric current and voltage, print the information of waveform, switching value sequence of movement, down time and the fault type of electric current and voltage.Electric parameters is gathered and analyzed, and the change procedure of record trouble and misoperation reproduces the electric parameters change procedure of fault and misoperation, as analyzing electric power system fault reason and the main foundation of searching the trouble spot.
