Description
Technical field
The invention belongs to the power automation field, be specifically related to a kind of secondary equipment of intelligent converting station dynamic reconfiguration system and method.
Background technology
2007, somewhere power supply administration has carried out statistic of classification to the substation secondary device that damages, by consulting the correct time of ruuning situation record, runtime environment temperature, weather condition and device damage, the concrete reason that packet lookup is damaged, and to causing the substation secondary device source of damage to be classified as follows shown in the table 1.
| Sequence number | Date | Project | Frequency | The accumulative total frequency | Accumulative total % |
| 1 | 2006.2～2006.11 | Be struck by lightning | 21 | 21 | 42.86％ |
| 2 | 2006.2～2006.11 | Operating ambient temperature is high | 13 | 34 | 69.39％ |
| 3 | 2006.2～2006.11 | Long operational time | 5 | 39 | 79.59％ |
| 4 | 2006.2～2006.11 | Ageing equipment | 5 | 44 | 89.80％ |
| 5 | 2006.2～2006.11 | The operation improper use | 3 | 47 | 95.92％ |
| 6 | 2006.2～2006.11 | Other | 2 | 49 | 100％ |
Statistics shows, causes the main cause of the non-artificial damage of substation secondary device to be: substation secondary device suffers thunderbolt, high, the long operational time of operating ambient temperature and ageing equipment.
There is research to point out; highly integrated CPU card, logica board etc. are arranged in secondary device; also have power insert, modulus or digital-to-analog conversion plug-in unit, LCDs etc.; be integrated with small-sized TV, the TA of a large amount of coil windings above such plug-in unit; because compact conformation, long time continuous working is added the dust accumulation in the running environment; its heat only by on the equipment with outer blow type radiator fan delivery ratio the difficulty, so need some peripheral apparatus such as air-conditioning, exhaust fan etc.When the weather conditions of fast season of temperature variation and high temperature, should fail in time to open air-conditioning for master-control room, central station of floating dock, when perhaps air-conditioning breaks down, can not keep suitable indoor temperature.Because conventional proof cycle is limited, can not in time find the running environment of secondary device operation, equipment can continuous working under the continuous high temperature condition, might cause the phenomenon of " electron transfer ".In case occur, situation can be more and more serious, to causing short circuit at last, various components and parts are damaged.In real time measures ambient temperature of temperature online monitoring system is installed in suggestion, so that the operations staff pinpoints the problems fast and in time processing.In addition, secondary device need to be changed it in operation a period of time, and every complete equipment has tenure of use, to the time limit in time change, prevent the plate fault that causes because of the plug-in unit oxidation.
Studies show that, flashover, thunderbolt shock wave are coupled by ground wire, produce superpotential and cause secondary device to damage, cause power grid accident or equipment breakdown, major measure is to eliminate the existence of interference source and cut off coupling channel, to the independent grounded screen of secondary device installing, suppresses earthy variation.
Statistics shows, certain 110kV intelligent substation is since operation time a year and a half, and secondary equipment of intelligent converting station power supply defective is more, mostly is random fault, is difficult for finding.
According to another the maintenance information of engineering staff feedback, the common fault of secondary device has that power supply, remote signalling plate, CPU network interface, remote measurement plate, exit plate relay are bad, program BUG.In fact; substation secondary device has possessed certain self-checking function; for example " Q/GDW 396-2009 IEC 61850 engineering relay protection application models " have defined the self-diagnostic function of each module of microcomputer protecting device; the running status of power supply, CPU, I/O interface, A/D conversion, storer and other plug-in unit of touring diagnostic device is by giving supervisory system on brcbAlarm, the brcbCommState switch fault report.
At present, some intelligent substation pilot has been used the secondary device repair based on condition of component of state-based variable on-line monitoring, but monitoring only is the running status of perception secondary device, can not satisfy autonomous and self-healing requirement, unattended station particularly, can't reach the spot the very first time to finish to overhaul when secondary device lost efficacy and resume operation, universal equipment has reduced the complexity of system simultaneously, has improved the reliability of system.
