Description
Technical field
The utility model belongs to the technical field of power network schedule automation, and specifically, the utility model relates to a kind of dispatching of power netwoks and electric quantity acquisition integrated universal simulation test system.
Background technology
Along with the continuous growth of user's request and the continuous propelling of electricity market process, power supply enterprise carries out tasks such as transformer station is newly-built, enlarging, transformation constantly to be increased.For providing the electric energy service of economy, high-quality, the user become certainty.At present, the system that has been absolutely necessary in power industry of power dispatching automation and electric flux system is for power grid security, economy, high-quality, reliability service have been brought into play crucial effects.
Production tasks such as transformer station transforms because power supply enterprise is faced with, newly-built, enlarging are more and more heavier, and personnel simplify relatively, when engineering is heavy, the dispatching automation specialty need be handled three or four scenes simultaneously, and concentrator station and scheduling station all will have people's uniting and adjustment, implement to have brought more inconvenience and challenge to field engineering, make that also the contradiction that the dispatching automation professional is in short supply and engineering is heavy is more outstanding with the engineering uniting and adjustment.
Along with computer, network technology and electric power are used fast development, the update cycle of scheduling station is also accelerating at present, carries out the primary system renewal in average 6 to 8 years, and the groundwork in early stage of update system is to insert telecontrol information, debugs.According to statistics, the average telemechanical debug time of regional dispatching system of administering 30 stations is about 3 months, the average debug time of concentrator station system of administering about 10 stations is about 2 months, the debugging cycle of administering the above large-scale dispatching patcher in 100 stations is just longer, also to arrange overhaul of the equipments between limber up period, carry out tests such as remote control, remote regulating.
Current, the EMS of each power scheduling (Energy Management System, EMS) main station system inserts the transformer station in the compass of competency and remote terminal unit (the Remote Terminal Unit of power plant by simulation, digital special line channel or network channel mode mostly, RTU), this main station system has become the important support platform of guaranteeing power grid security, stable, economy, high-quality operation, and its function and effect have become the indispensable important means of dispatching of power netwoks operational management.And the normal performance and the use of these functions, then be unable to do without factory's station end remote action data accurate, complete, reach continual transmission fast.If there is not the basic data of these telemechanicals, so, the EMS main station system can become cooks a meal without rice water without a source.
Before new transformer station puts into operation, or before a transformer station transforms operation, all to expend a large amount of time and efforts and main website and carry out the information debugging, to guarantee the normal use of comprehensive automation system of transformer substation.The content of debugging comprises that lane testing, stipulations test, remote measure and communication measure examination, remote control remote regulating, electric quantity test.And telecontrol channel be transformer station's field data and data can teletransmission prerequisite.If a reliable passage can not be provided, other test can't be carried out at all.After reliable channel has been arranged, also to expend huge workload to the test of amount of information.Whether all correct as the remote measurement value; Whether no-load voltage ratio that is provided and coefficient be correct; The remote signalling amount is wanted each, and test is guaranteeing that wiring is correct separately, and it is correct etc. that database is filled in.The test of remote control must be carried out especially in strictness, often because the problems such as remote control numbers of pressing plate, wiring, database lead to the failure or problem such as mistake control.All above debugging are all quite wasted time and energy, even reliable passage has been arranged, also between main website and factory station, link up by phone repeatedly, and quite inconvenience, this also causes the cycle of debugging very long.
In sum, the access of telecontrol channel and the step of test have following deficiency at present:
1, manual test is wasted time and energy, and the cycle is very long;
2, periodicity and repeatability, main station system is changed and just need be tested again one time each time;

4, manual operation is difficult to avoid not makeing mistakes.
At present, along with the continuous development of power system dispatching automation technique, the passage uniting and adjustment testing tool between the on-the-spot substation of dispatching automation main station system and transformer station is also more and more.
ABY-9000 supports that simulation main website end four send on distant, remote control issues etc., and testing response time also is provided; As the substation end, provide the simulation of communication data; Quality for passage also has corresponding statistics (stipulations Bit Error Code Statistics).
SGH-1000 function and ABY-9000 are more or less the same, and the main distinction is that all softwares of ABY-9000 and interface are integrated on the equipment, the method that SGH-1000 then adopts interface equipment to separate with software, and software can be installed on computers.
The more preceding two kinds of supports for stipulations of SACO6000 are more weak, only 104 support the distant arteries and veins remote control of remote measure and communication remote regulating, other stipulations support that (product parameters shows for remote measurement, remote signalling, distant arteries and veins, remain to be confirmed), but this system provides one-touch quick file transmitting method, do not need to understand concrete message content during user test, just can directly send corresponding message.
The BTS-1000 system advantage is to provide the plug-in type stipulations, auto-update on the net, and this point is better than top system.
Other products such as XG2056 are exactly the function of some tests comparatively speaking, a little less than the systemic-function of front some, but the XG series of products are smaller, are convenient for carrying.
Because the said goods mainly biases toward the detection of communication equipment and the simple test of stipulations, use face is narrow, do not realize inserting and the debugging scheme from the substation to the main website global optimization, so the said goods is not very high in the occupation rate of market of power supply department, in addition, stipulations are of less types and means of testing is complete inadequately, also limited use.
