Description

A kind of electric energy quality on-line monitoring device

Technical field

The utility model relates to power quality on-line monitoring technique field, specially a kind of power quality on-line monitoring dress It sets.

Background technique

With high-power electric and electronic product be widely used and other be poised for battle property, nonlinear-load capacity it is continuous The problem of increasing, voltage waveform distortion, voltage fluctuation and the power qualities such as flickering and tri-phase unbalance factor occur in power grid is increasingly Seriously.Existing power quality on-line monitoring product mostly uses greatly standard handovers format of the PQDIF as power quality, but uses PQDIF file converts in transient event monitoring and real time data the data being easy to cause between distinct device with limitation not It is compatible, data communication is influenced, therefore how to invent a kind of standard handovers format that can replace PQDIF as power quality, made Data compatibility between distinct device improves the electric energy quality on-line monitoring device of data communication quality, is current this technology neck Domain personnel's urgent problem to be solved.

Utility model content

The purpose of this utility model is to provide a kind of electric energy quality on-line monitoring devices, to solve in above-mentioned background technique The power quality on-line monitoring product of proposition mostly uses greatly standard handovers format of the PQDIF as power quality, but uses PQDIF file converts in transient event monitoring and real time data the data being easy to cause between distinct device with limitation not The problem of being compatible with, influencing data communication.

To achieve the above object, the utility model provides the following technical solutions: a kind of electric energy quality on-line monitoring device, packet ARM control module is included, the ARM control module, which electrically exports, connects display, the ARM control module electrical property input keyboard, The ARM control module is electrically bi-directionally connected FLSH register, Ethernet interface and FPGA data processing module respectively, described Electrically input connection A/D conversion module, the A/D conversion module electrically input connection signal and improve mould FPGA data processing module Block, electrically input connects voltage transformer and current transformer to the signal conditioning module respectively.

Preferably, the chip of the A/D conversion module is AD7606.

Preferably, the display is LCD chromatic liquid crystal screen.

Preferably, the concrete model of the FLSH register is F28335.

Compared with prior art, the utility model has the beneficial effects that this kind of electric energy quality on-line monitoring device, it is contemplated that PQDIF file is monitored in transient event and the limitation of real time data guarantees on the basis of realizing that power quality function is realized Data compatibility between distinct device directly solves the problems, such as data compatibility from mechanical floor, realizes and uses IEC61850 standard agreement and master It stands and carries out data communication.

Detailed description of the invention

Fig. 1 is Tthe utility model system functional block diagram.

In figure: 1 ARM control module, 2 displays, 3 keyboards, 4 FLASH registers, 5 Ethernet interfaces, 6 FPGA Data processing module, 7 A/D conversion modules, 8 signal conditioning modules, 9 voltage transformers, 10 current transformers.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of electric energy quality on-line monitoring device, including ARM Control module 1, for ARM control module 1 using Linux embedded OS as software platform, ARM control module 1 is external FLASH register 4 can save in real time fundamental surveillance index and advanced monitoring index, update according to first in first out, described Electrically output connects display 2, the electrical input keyboard 3 of the ARM control module 1, keyboard 3 and display 2 to ARM control module 1 The human-computer interaction of composition carries out Development of Graphical Interfaces, the electrically two-way company of the difference of ARM control module 1 using Qt/Embedded FLSH register 4, Ethernet interface 5 and FPGA data processing module 6 are connect, ARM control module 1 is by Ethernet interface 5 to mark Quasi- IEC61850 agreement and distant place Power quality management center communicate, and a reserved debugging serial interface and RS232 interface facilitate debugging And downloading program, electrically input connection A/D conversion module 7, the A/D conversion module 7 are electrical for the FPGA data processing module 6 Connection signal conditioning module 8 is inputted, electrically input connects voltage transformer 9 and Current Mutual Inductance to the signal conditioning module 8 respectively Device 10.
