Technical field
The utility model relates to power network monitoring apparatus field, is specifically related to a kind of portable grid loss monitoring system.
Background technology
In recent years, China is every year because the electricity of line loss problem loss reaches tens billion of kilowatt hour.Relative to 35kV and above network system, 10kV distribution network systems line loss per unit is higher.Current power department all formulates year, season, monthly line loss plan target for taking reducing loss measure to provide foundation further by theoretical line loss caluclation and long-time statistical data; Along with the development of China's electric power energy industry, existing electric power checkout equipment, because configuration is lower, function singleness, extended capability are poor, mobile use is inconvenient, can not meet the diversified demand of work at present.Such as, the main control unit model that existing electric power checkout equipment adopts is comparatively old, and Resources on Chip is limited, and data-handling capacity is poor; Data transfer mode is single, can not be used for industrial site or the commercial location receiving radio data of some difficult wiring; Man-machine interaction mode is single, lacks friendly user interactions mode; And moved by hand gathers the problems such as inconvenience.
Utility model content
The utility model is for the deficiencies in the prior art, a kind of structure is proposed simple, easy to operate, intelligence degree is high, can the voltage of collecting device, electric current, meritorious, idle data, to compare the portable grid loss monitoring system of calculating, the loss value of monitoring equipment self and electrical network with head end data, concrete technical scheme is as follows:
A kind of portable grid loss monitoring system, be provided with central processing unit (1), the communication ends of this central processing unit (1) is connected with wireless communication module (2), meritorious collection terminal is connected with on-the-spot meritorious table (3), idle collection terminal is connected with on-the-spot idle table (4), electric current and voltage collection terminal is connected with digital processing unit (5), A/D modular converter (6) and signal adjustment circuit (7) in turn, and the input end of this signal adjustment circuit (7) is connected to voltage transformer (VT) (8) summation current transformer (9); The display end of described central processing unit (1) is connected with display apparatus module (10), and input end is connected with input keyboard (11), stores end and is connected with storer (12).
The utility model realizes like this, central processing unit (1) gathers the meritorious of equipment under test by on-the-spot meritorious table (3) and the idle table in scene (4), idle data, voltage transformer (VT) (8) summation current transformer (9) is by equipment voltage and current data, after signal adjustment circuit (7) shaping, send in A/D modular converter (6) and be converted to digital signal, this digital signal is after digital processing unit (5) analyzing and processing, be supplied to central processing unit (1), user manually inputs electrical network head end and gains merit, idle, the data such as head end electric current, or the electrical network head end that wireless communication module (2) directly gathers is gained merit, idle, head end current data, after central processing unit (1) is analyzed field data and head end data, draw loss conclusion, and related data and conclusion information are shown by display apparatus module (10).
For better realizing the utility model, may further be:
Described wireless communication module (2) connects respectively with head end reometer (13), total idle table (14) with total meritorious show (15) and be connected by network, wireless mode is adopted to communicate with head end device, structure is simple, acquisition speed is fast, not by the impact of environment.
Described central processing unit (1) is ARM microprocessor, concrete model is S3C2410, the maximum advantage of ARM microprocessor is that speed is fast, low-power consumption, high-performance, chip integration are high, and the price of ARM chip is also only a little more than single-chip microcomputer, ARM chip can transplant embedded real-time operating system, easily realize multi-task scheduling, and simplify the exploitation of the functions such as LCD display, hard-disc storage, network service, greatly reduce the construction cycle of product.
The model of described digital processing unit (5) chip is TMS320F2812, A/D modular converter (6) chip model is ADS8365.The utility model can guarantee sufficiently high sampling rate by digital signal processor (DSP) TMS320F2812 chip, reach as high as each cycle 1024 point, data operation speed is fast, this device adopts ADS8365 chip to carry out data A/D conversion and gather simultaneously, thus realize high-precision multi-channel data process, meanwhile, general High Degree Harmonic Wave in Power System content is lower, when using the resolution of A/D chip to only have 12, the conversion accuracy of A/D converter chip is inadequate, certain error can be caused to higher hamonic wave, therefore the A/D converter chip selecting high-resolution in measuring unit is needed, consider that cost factor selects sexual valence higher, low-power consumption 6 passage 16 A/D converter ADS8365 chips, this chip provides a high speed parallel interface flexibly, can directly be connected with dsp chip.
The beneficial effects of the utility model are: one-piece construction is simple, easy to operate, collection in worksite end is removable, only need corresponding instrument and mutual inductor be connected on equipment under test, get final product the power consumption situation of Quick Acquisition equipment under test, wirelessly gathering head end electric power data, after comparing, accurately draw lossy data, take corresponding measure for lossy data, electrical network is optimized.
