Source.
In order to enable those skilled in the art to better understand the solution of the present invention, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention are described, it is clear that described embodiment is only present invention a part
Embodiment, instead of all the embodiments.Based on the embodiments of the present invention, it should fall within the scope of the present invention.
On the basis of existing communication agreement, the present invention proposes a kind of feasible method of low cost, is not changing original son
Under the premise of soft and hardware and the overall system structure of standing, by designing new software algorithm in main station side, substation is handled to realize
Recorder data and the evaluation for reporting recording bulletin information performance.
Below for the embodiment of the present invention fall into a trap operator station recording bulletin data processing time principle explanation:
When grid collapses or device operation occur abnormal, prudential sub-station can be by the action message of device or abnormal letter
Breath is converted to 103 message formats, and active upload quickly handled after receiving information so as to main website to main website, to tune
Degree person and protection staff carry out the alarm prompts such as failure, exception, and provide necessary data for accident analysis and support.
Prudential sub-station can also be referred to as substation, sub-station device, and the information of active upload mainly includes warning information, event
Information and recording bulletin information are respectively that 1,2 and 12 application layer data units are reported and (can be used in the present embodiment with number
ASDU1/ASDU2/ASDU12 is indicated).Alarm, event information transfer mechanism and recording bulletin transfer mechanism it is different:
The warning information and event information that protective device generates, generally by station communication network, active reporting is to sub-station device, substation
Device should actively be transmitted to main website in the first time for receiving protective device information；The recording bulletin information that protective device generates,
Equally by station communication network, active reporting is answered after receiving the recording bulletin information of protection to sub-station device, sub-station device
Corresponding recorder data is called to protective device in time and is stored in the local memory device of substation, is then pushed to main station system
Recording bulletin information.
As shown in Figure 1, for the timing diagram of alarm/event communication in the embodiment of the present invention.As shown in Fig. 2, real for the present invention
Apply the timing diagram that recording bulletin communicates in example.
In timing diagram shown in Fig. 2, the delay that protective device wave-record chart reports is that failure record is generated from protective device
Wave information time tdStart, the time t of recording bulletin ASDU12 message is received to main websitemUntil, delay time TdlyAre as follows:
Tdly=tm-td
If the recording bulletin ASDU12 message time that substation receives protective device generation is ts1, recording letter is sent to main website
Reporting ASDU12 message time is ts2, the T of data network transmission delayl, then the time T of substation handling failure recorder data are as follows:
T=ts2-ts1=tm-ts1-Tl
Therefore, if main website can obtain protective device generate recorder data time and main website receive ASDU12 message when
Between, it can acquire the delay time that recording bulletin data report；If it is known that substation receive protective device information time and
Data network link delay, it can acquire the time used in substation processing data.Through due to the information that protective device generates and change
Power station local networks are transferred to substation, and the time for handling recorder data relative to substation and data network chain road delay time numerical value are very
Small (protective device reports information time to have special test), therefore for ease of calculation, it is believed that substation receives protective device
The time of fault message is approximately equal to the time that protective device generates fault data, the also approximately equal to time of failure generation, it may be assumed that
ts1≈td
In 103 communication protocol specifications, without special data network link delay test method, find after study, it can
To use link layer test frame to reach measurement TlPurpose.The time t for the request for test frame that record main website is sent respectively0With receive
The time t for the confirmation test frame that substation is answered1, then link transmission times can be calculated by following mode:
Tl=(t1-t0)/2
Protective device generates Fault Recorder Information time tdIt can be replaced with the time that failure occurs.Protective device is detecting
When to electric network fault, markers can be stamped to fault recorder data, which is generated by the clock that protective device is kept, and in recording
Sub-station device is transmitted in bulletin data, " fault time " domain section of the sub-station device in ASDU12 is filled in the markers and be reported to
Main website, the value are the markers t in protective device time systemf。
Since the time source of main website and substation and protective device is different, such as main website uses NTP in main station side net
Acquisition time in network, stand in protective device when generally using GPS or pulse synchronous signal, and in standing protective device exist by
The markers abnormal phenomenon caused by time source failure.Therefore, main website and protective device time are in different time system, lead
Cause main website that can not be computed correctly substation truthful data and report delay time, at the same also can not each substation of lateral comparison performance.
Therefore, main station side needs to be unified in markers in system at the same time, i.e., by tfIt is transformed into main station time td, with
Just it is calculated and is analyzed.According to code requirement, substation should pass the alarm/event information that protective device reports to main website immediately
It is defeated, therefore can use this characteristic, estimate the discrepancy delta T of the time system of protective device time system and main station system:
Δ T=tm-[tf+(ts2-ts1)+Tl]
Since the information is transmitted in substation immediately after receiving protective device information, can will receive protective device information to
The time that main website is sent between information ignores, it may be assumed that
ts2-ts1≈0
Then: Δ T=tm-(tf+Tl)
Δ T is brought into the time t for adjusting each recording bulletin and generating in protective devicef, have:
td=tf+ΔT
Thus, it is possible to calculate this recording bulletin data approximate processing time of substation T and approximate transmission delay Tdly。
Below by way of examples, technical solution of the present invention is described further, as shown in figure 3, for the present invention
Embodiment fall into a trap operator station recording bulletin data processing time method embodiment schematic diagram.In order to calculate substation recording bulletin
Data processing time, main station side are divided into 3 sub-function modules, are respectively as follows: link delay calculating, protective device markers adjusted value meter
