Abstract
The invention discloses a method for acquiring a multi-partition relay protection setting value. The method comprises the steps of acquiring the current setting value partition number from a protection information system, then acquiring a protection setting value corresponding to the partition from a relay protection setting value off-line setting database, leading out the protection setting value to a local data file, calling an FTP command to upload protection setting value data to a server appointed by a safety region III, automatically triggering and pushing the file to a data server of an on-line relay protection setting value checking system in a safety region II if a reverse isolation device detects updating of the file, leading the setting value data into the database by the on-line relay protection setting value checking system through name fuzzy matching, and mapping the setting value data to corresponding primary equipment of a power grid.
Description
Technical field
The invention belongs to field of relay protection in power, more particularly the present invention relates to a kind of acquisition methods of multi partition relay protection constant value.
Background technology
Traditional relay protection fixed value setting computational methods are on the normal mode basis of operation of power networks, according to the day-to-day operation rule of electrical network, the usual manner of considering protective device perimeter circuit and plant stand changes, determine the harshest mode, by ensureing that under the harshest mode, definite value meets " four property " (reliability, quick-action, sensitivity and selectivity) requirement determine protection definite value, and the line that returns back out of the same transformer station causing for capital construction or electric network reconstruction project is stopped transport more simultaneously, the special operational modes such as large power plant full cut-off, have little time to check the definite value of protective relaying device around.Obviously, arrange once the operational mode of system has exceeded daily mode, exceeded the limit of consideration of off-line setting calculation mode, just may have the accident potential of protection malfunction or tripping, the coverage that causes the accident expands, and then may cause electrical network major accident.In recent years, along with the fast development of electrical network, electrical network capital construction, power supply are sent, electric network reconstruction project is gone into operation in a large number, and relay protection fixed value setting evaluation work can not meet the requirement of its production cycle.In capital construction, technological transformation project operation process; the bus causing accompany stop, circuit is accompanied the mode of stopping, electrical network abscission ring mode becomes increasingly complex; electrical network abnormal running mode showed increased, the time extends more, has brought huge challenge to current relay protection fixed value setting evaluation work.Therefore, increasing experts and scholars online check, the on-line tuning of relay protection constant value that begin one's study.
China's patent application number is the real-time running data that " electric grid relay protection constant value on-line check integrated data processing method " that 200810147821.2 " relay protection on-line check method for electric grid system " and application number are 200810147822.7 proposed to obtain from electrical network by EMS and DTS power equipment parameter and electrical network; then carry out calculation of fault according to the protection code of adjusting, finally according to checking rule, protection definite value is checked.But above-mentioned patented method does not relate to the data-interface of online relay setting check system and existing relay protection constant value off-line setting calculation system and protection information system, do not relate to the acquisition methods of protection definite value.
There are multiple subregions in the protective device definite value of on-the-spot operation, in the time that power system operating mode changes, needs frequent switching protection definite value subregion.If from whole protection definite values of the current subregion of protection information system acquisition, communication condition is had relatively high expectations, consider the technical conditions of current protection information system, the speed of obtaining on-the-spot all operations definite value is very slow.Protect the speed of definite value very fast and obtain from relay protection constant value off-line setting calculation database, but cannot obtain the residing subregion of current protective device definite value.Relay protection constant value off-line setting calculation database can be preserved multiple engineerings, a corresponding definite value subregion of engineering.
Generally, relay protection constant value on-line check system layout is in safe II district, and relay protection constant value off-line setting calculation system layout is in safe III district, and WangII district of CongIII district transmits file need to pass safety insulating device.
In view of above analysis, the inventor checks for current relay protection constant value the problem existing in evaluation work practice and carries out Improvement, and this case produces thus.
Summary of the invention
Technical problem to be solved by this invention; for the defect in aforementioned background art and deficiency; a kind of acquisition methods of multi partition relay protection constant value is provided; from the current definite value partition number of protection information system acquisition; obtain protection definite value that should subregion from relay protection constant value off-line setting calculation database, carry out relay protection constant value on-line check evaluation work.
The present invention is for solving above technical problem, and the technical scheme adopting is: a kind of acquisition methods of multi partition relay protection constant value, comprises the steps:
(1) from the current definite value partition number of protection information system acquisition;
(2) obtain the protection definite value of respective partition from relay protection constant value off-line setting calculation database;
On relay protection constant value off-line setting calculation database server, configure derivation program, derive protection value data file from database, be stored in this locality;
(3) call FTP order protection value data file is uploaded to the server that safe III district specifies;
(4) reverse isolation device detects after file update, automatically triggers and is pushed to the relay protection constant value on-line check system data server that is positioned at safe II district;
(5) value data is imported to database by relay protection constant value on-line check system.
Further, described step (1), from the current definite value partition number of protection information system acquisition, is divided into two kinds of situations, and the one, the whole network is unified change partitions, and the 2nd, each plant stand is change partitions respectively, i.e. a corresponding partition number of plant stand.
Further; the protection definite value of obtaining respective partition from relay protection constant value off-line setting calculation database in described step (2) can have two kinds of methods; the one, the protection definite value that runs into non-current subregion when reading database is directly skipped; the 2nd, the protection definite value that derives whole subregions is stored in respectively different files, only uploads the protection definite value file of current subregion.
Further, in described step (3), upload which file, upload the cycle, ftp server IP address and directory path can flexible configuration.
Further: in described step (4), reverse isolation device can regularly detect file update, also can detect in real time file update.
Further: when value data is imported to database by described step (5) relay protection constant value on-line check system, by title fuzzy matching, protection definite value is associated to corresponding electrical network primary equipment.
Adopt after such scheme, the invention has the beneficial effects as follows: the protection definite value of can be automatically obtaining current subregion from relay protection constant value off-line setting calculation database is carried out check evaluation work, reduces maintenance workload.Can obtain protection value data file in cross-safety zone.
