Description
Technical field
The present invention relates to a kind of office and put (shelf depreciation) intelligent assembly check system and method, belonging to is on-site calibrating method and the technology that intelligent assembly is put in GIS office.
Background technology
Current intelligent substation comprises the multiclass on-Line Monitor Device such as GIS office puts, GIS air chamber, breaker mechanic property, leakage current of an arrester, transformer core, transformer oil chromatographic and temperature of oil in transformer.Because intelligent substation has installed a large amount of sensors and on-line monitoring system device, the important component part that smart machine carries out regular maintenance is become to the verification of the validity of these sensors and on-Line Monitor Device parameter measurement, accuracy and reliability.
Jiangsu Power Company is the unit of domestic first batch of employing intelligent substation pilot, state net first pilot 220kV intelligent substation Xi Jing become put into operation after, organizational strength is analyzed and studies intelligent substation crucial smart machine regular maintenance scheme and put into practice, and achieves certain achievement.Also see up till now many weak points are also existed to the regular maintenance scheme of on-Line Monitor Device by putting into practice us:
Mostly carried out complete test when on-Line Monitor Device is dispatched from the factory, but field-checking and laboratory verify and be very different, only School Affairs inspection is carried out to the partial function of on-Line Monitor Device at present, do not realize covering comprehensively.Such as on-Line Monitor Device is put in GIS office, simulating signal is only adopted to carry out functional verification to IED at present, sensor is put to the critical component office of system and lacks effective detection means, whether that cannot understand that sensor is in operation characterisitic parameter there occurs change, and the design function of the defect type putting IED of playing a game also lacks corresponding verification means.Similar situation is also present in other on-Line Monitor Device, therefore studies the field-checking technology of such device and develops associated check device, and the key parameter covering on-Line Monitor Device is the task of top priority.
At present all with functional, master is verified as to the field-checking of most of on-Line Monitor Device, verification means are fairly simple, lack complete technical system, deep research is not carried out to the validity of check results, accuracy and reliability, therefore the calibration technology of necessary comprehensive system ground research on-Line Monitor Device, improves validity and the accuracy of check results.
Current employing be that School Affairs detection is carried out to single on-Line Monitor Device, and many on-Line Monitor Device even do not consider the requirement of field-checking in operation, and it is quite complicated that field-checking disconnects line, brings very large difficulty to the enforcement of field-checking.In addition on-line monitoring system is split separately to come to have verified also one by one and increase workload, also reduce the reliability of system simultaneously.
