Intelligent substation networking TT&C system and method thereof
Technical field
What the present invention relates to is the device and method in a kind of intelligent substation secondary control technology field, specifically is a kind of intelligent substation networking TT&C system and method thereof.
Background technology
The IEC61850 system is the structure system that the propelling of intelligent substation engineering provides transformer station's information flow; " three layer of two net " structure becomes the key character that intelligent substation is different from conventional substation; Information " gather at a place; share at full station " has demonstrated fully the convenience that intelligent substation information " is called " as required, and has constituted the basis of " self-healing " type intelligent grid.
Along with the propelling of intelligent substation technology, protective relaying device is changed on the spot will become a kind of inevitable development trend, and main cause is that first and second equipment can connect in factory's completion, test, has very big realistic meaning for simplifying the transformer substation construction process.If protection is changed on the spot is development trend, the propelling of transformer station's unattended operation pattern, and the application model that the conventional substation automated system relates to measure and control device, monitoring backstage, the telemechanical communication server faces the challenge that networking technology is used.
Intelligent substation secondary control technology relates generally to two professional domains at present; First relaying protection field; Quick isolated fault point when the electrical network primary equipment breaks down; Recover electrical network and normally move, the equipment category is the secondary circuit that connects electric current, voltage transformer, the breaker tripping and closing operation circuit (control box etc.) of protective relaying device itself, connection circuit breaker.It two is automatic fields, transformer station's electric operation of normal operation, the anti-misoperation locking between the interval under the maintenance pattern, go up the on-the-spot transformer station of pushing electric network control centre the electric parameters operation information, carry out from the control command of grid dispatching center etc.Whole automatic field Constitution ratio of plant is complicated, and the monitoring background system of using based on measure and control device at interval, " anti-misoperation locking " system that prevents misoperation, responsible transformer station information stores, full station, the telemechanical communication server of being responsible for remote data transmission etc. are arranged.
For solving transformer station's information synchronization precision problem, IEC TC57 working group has increased IEC 61850-90-4 standard newly, as Ethernet switch engineering construction guide rule (Guidelines of Ethernet Network Switch Engineering).Clearly adopt IEC 61588 (quoting the IEEE1588 standard basically) agreement realize network to the time microsecond accuracy; Realize the solution that the full transformer station scope time distributes with IEC 61588 through network, transformer station formulate network to the time standard provide file " IEEE 1588 Precision Time Protocol are used for the ieee standard protocol suite that protecting electrical power system etc. is used " by name.Therefore, intelligent substation is through the building process layer network, and automated system can obtain the information of " unique, synchronous, standard, full station ", and on this basis, information is used and is presented as the characteristic that integrated level is higher.
