Abstract
An intelligent substation digital statistical type voltage monitor comprises a statistical type voltmeter. A human-computer interaction interface composed of a display screen and buttons is arranged on a front face of a voltmeter shell of the voltmeter. A 100M/1000M self-adaptive Ethernet interface which conducts data exchange with a combined unit according to an IEC61850-9-2 standard and a 100M/1000M self-adaptive Ethernet interface which is communicated with a main station front-end processor are respectively arranged at side portions of the voltmeter shell. A statistical type voltmeter main machine with data storage and statistics functions is arranged in the voltmeter shell. The intelligent substation digital statistical type voltage monitor can achieve secondary output and sampling to a non-traditional mutual inductor and has the functions of digital voltage signal statistics analysis and intelligentized advanced applications.
Description
Technical field
What the present invention relates to is collection, statistics and the transmitting device of the digital voltage information of the unconventional mutual inductor output of a kind of intelligent substation of the IEC61850 of employing standard.
Background technology
The voltage detecting statistic device, it is the statistical voltage table, generally adopt traditionally analog acquisition, transmission interface is based on RS-232 or the RS-485 of serial port protocol substantially, be widely applied in conventional substation, according to Electricity Monitoring Commission's relevant regulations, it is the requisite standard facility of transformer station's energy monitor.
Along with the all-round popularization that intelligent substation is built, unconventional mutual inductor (electronic type, optical fiber type etc.) and IEC61850 technical standard have obtained extensive application in Practical Project.But current traditional statistical voltage monitoring instrument can only gather the analog quantity voltage signal, does not support the IEC61850 standard, and does not possess the senior application function of Extraordinary.Therefore, how the intelligent substation quality of power supply is gathered, adds up and transmission is intelligent substation problem needing to overcome in service.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of intelligent substation based on the IEC61850 standard digital statistical voltage monitoring instrument, in order to realize, non-traditional mutual inductor secondary output sampling is possessed the digital voltage signal statistics and analyzes and intelligent senior application function.
The objective of the invention is to complete by following technical solution, it includes a statistical voltage table, the watchcase front of this statistical voltage table is provided with the human-computer interaction interface that is made of display screen, button, and the sidepiece of watchcase is respectively arranged with merge cells and carries out the 100M/1000M self-adaptation Ethernet interface of exchanges data and the 100M/1000M self-adaptation Ethernet interface that carries out communication with the main website front end processor according to the IEC61850-9-2 standard; , statistical voltage table main frame that have statistical function storage with data are installed in described watchcase.
The present invention can follow three voltage channel waveform sampling data that the IEC61850-9-2 standard is obtained a merge cells, carries out integral operation according to 10 cycle data and obtains voltage effective value.
The present invention can require to carry out according to " DL/T 500-2009 voltage monitoring instrument technical manual " statistics of rate of qualified voltage, respectively according to adding up day and the moon: qualification rate, super upper limit rate, super lower limit rate, timing statistics, qualified time, super upper limit time, super lower limit time, maximal value, maximal value time of origin, minimum value, minimum value time of origin, average voltage, totally ten two sports [2].
The present invention has following technical characterstic:
1) follow the intelligent substation standards system fully, according to the Intelligent voltage monitor of IEC61850 standard access, realize the intelligent transformer substation voltage monitoring has been solved the problem that traditional voltage monitoring instrument can't access Intelligent transformer station;
2) high performance hardware and software platform, digital intelligent interface possess the ability that the power quality indexs such as harmonic wave, simple harmonic wave, tri-phase unbalance factor, fluctuation and flickering are monitored in expansion.Traditional voltage monitoring instrument can only monitoring voltage qualification rate index, do not possess on the one hand the detectability of other voltage indexs of correlation of expansion, in addition on the one hand because it adopts fixed-analog passage input mode, can't expand the ability that gathers current signal, more specifically not monitor index relevant to electric current, power etc. in the quality of power supply;
3) reduce periodically verification complexity, can easily complete at the scene verifying work.The Intelligent voltage monitor is the pure digi-tal processing, need provide high-precision standard source to come calibrated analog device aging, decay unlike the conventional voltage monitor and the error that causes, only needs get final product by the digitizing verification;
4) the Intelligent voltage monitor has improved maintainability, stability and reliability greatly; On the one hand, Intelligent voltage monitor complete machine is all weak electricity system except power supply, does not all need to be directly involved in traditional PT loop in Installation and Debugging, maintenance process, improves convenience and the work efficiency of work, reduces accident probability; On the one hand the instrument complete machine is the digitizing parts in addition, and stability and reliability aspect all have greatly improved than traditional voltage monitoring instrument.
