Description
Technical field
The utility model relates to a kind of supervisory control system, relates in particular to a kind of supervisory control system of process layer of digitalization transformer substation communication.
Background technology
In recent years, computer technology, the information processing technology and network communications technology development are rapidly, electric substation automation system has been produced tremendous influence, as everyone knows, the digital power system helps to realize the scientific management and the decision-making of electric power system, helps system mode is carried out real-time assessment, improves the security and stability of system, formulate and the enforcement economic operation strategy, help electric power system to implement emergency control and the control of anti-accident.Therefore, digital transformer substation will be the developing direction and the inexorable trend of automation of transformation substations technology.
Along with the ripe gradually of digital transformer substation technical application and deeply, the application implementation of digital transformer substation is from developing into the procedure-oriented layer towards substation level and wall at first, the appearance of process layer is the key character that digital transformer substation is different from traditional transformer station, particularly measure loop and control loop, especially the application of electronic mutual inductor and intelligent switch is ripe gradually, the design of transformer station secondary system, install, debugging and operation maintenance all will produce deep change, and whether the process layer can work accurately and reliably to replace the measurement loop of traditional transformer station, secondary circuits such as control loop become the key of digital transformer substation.
As shown in Figure 1, in digital transformer substation, the secondary circuit signal of process layer then is after elder generation changes by A/D, with all uniform datas packings, passes to relevant protection/measure and control device by Ethernet then and handles.Because the secondary circuit of digital transformer station is by realizing that based on data transmission of Ethernet there is following unreliable factor in the substation secondary loop than traditional:
Synchronism
The secondary circuit of digital transformer substation adopts the asynchronous digital transmission, on present automation logic basis of invariable, if the signal of asynchronous digital transmission loses synchronism, will bring very big hidden danger to the reliability of digital transformer substation, for sampled data, synchronism mainly shows the real-time of measurement data, and above the consistency of frequency acquisition.
Reliability
Digital transformer substation adopts Digital Transmission, and the judgement of secondary circuit broken string will be complicated and various more, propose higher requirement also for each automation cell, bring bigger hidden danger also for the reliability service of digital transformer substation.
Antijamming capability
Digital transformer substation adopts after the Digital Transmission, and the situation of the interference of signal will be more, and message transmission is made mistakes, and frame losing or the transmission of other messages on link, the generation of this type of situation all will be the hidden danger of digital transformer substation operation.
