Brief description
Fig. 1 is the flow chart that the present invention is applied to intelligent substation switch message forwarding method,
Fig. 2 is the flow chart of forward table checking procedure in Fig. 1,
Fig. 3 is the schematic diagram provided by the present invention for intelligent substation switch message forwarding system
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail.
The present invention provides a kind of self-defined forward table based on the identification of smart machine title being applied to intelligent substation
Switch message forwarding method, including below scheme, as shown in Figure 1：
Step 1, smart machine are sorted out：Secondary device species in intelligent substation base after intelligent substation complete design
This determination, this step needs to count the number of devices in this intelligent substation and species after completing intelligent substation design, such as
How many platform route protection of this station, how many observing and controlling etc..
Function control block (FCB) in described intelligent substation is carried out with statistics sort out, function control block (FCB) refers in intelligent substation system
The control block message of a specific function is completed, function control block (FCB) is the subset of smart machine, and that is, same smart machine can in system
Comprise different function control block (FCB)s.
Step 2, smart machine name definition.
On the basis of this step sorts out statistics in the smart machine that previous step completes, complete the name to all kinds of smart machines
In weighed justice, name definition is in the form of English character, case sensitive, can be by a smart machine during name definition
Applied environment feature interpretation more clear, Ru Yitai is applied to the measuring and controlling equipment of xx circuit, by its name definition can be
Xxck etc., this definition mode is completely combined power system service feature, can be popularized by problem, beneficial to power system O＆M people
The identification of member and use.The basic principle of this step is can not to duplicate between smart machine name definition, i.e. a title
A corresponding smart machine, single smart machine is existed multiple difference purposes control block in the case of, can exist further
Defined in title, control block purposes is to show difference.
Wherein formulating of the naming rule of smart machine needs to require the understanding with operation maintenance personnel according to Operation of Electric Systems
Mode is carried out, thus ensureing that the smart machine name definition one side generating meets power system requirements, two aspects are easy to O＆M
Personnel understand.
Step 3, self-defined forward table.
After completing smart machine name definition, technical staff is in SCD file according to intelligent substation configuration file
Definition smart machine subscribing relationship, complete the foundation of self-defined forward table, forward table mainly has two entries, that is, subscriber and
Subscribed side.The smart machine title of previous definition only need to be inserted this table according to the subscribing relationship in SCD file by technical staff
?.
Step 4, forward table verification：
This step mainly completes the rational verifying work to previously several step, and plausibility check work mainly has two
, Section 1 is to carry out the reasonability of smart machine title and the anti-school of smart machine according to customed smart machine title
Test, can ensure that the integrality of the smart machine in self-defined forward table and the reasonability of title by this inspection.Section 2
For verifying the correctness of forward table, retouched by compareing the subscription both sides in subscribing relationship verification forward table specified in SCD file
Whether correct state.
As shown in Fig. 2 verification forward table comprises the steps：
Step a, described smart machine title is counted；
Whether step b, described smart machine title meet naming rule, if meeting, execution step c, and otherwise title is entered
Row is revised, and jumps to step a；
Naming rule is a kind of a kind of specific agreed specifications for smart machine name nominating, that is, wish in smart machine
Title in embody interval information and function information belonging to this equipment, such as 110kV cyclopentadienyl literary composition line combining unit, embody in its title
The affiliated interval information of this smart machine is 110kV cyclopentadienyl literary composition line and function information is combining unit, completes data sampling function.
Step c, to forward subscription count；
Whether the subscription both sides description that step d, subscribing relationship specified in comparison SCD file verify in forward table is correct,
If correct, verification terminates, and otherwise subscribing relationship is modified, and jumps to step c.
As shown in figure 3, a kind of be applied to the system that intelligent substation switch message forwards, described system includes phase successively
Smart machine classifying module even, smart machine name definition module, self-defined forward table module and forward table correction verification module, institute
State smart machine classifying module, for counting the value volume and range of product of smart machine in intelligent substation；
Described smart machine name definition module, for defining the title of described smart machine；
Described self-defined forward table module, for self-defined forward table；
Described forward table correction verification module, for verifying forward table.
Finally it should be noted that：Above example is only not intended to limit in order to technical scheme to be described, to the greatest extent
Pipe has been described in detail to the present invention with reference to above-described embodiment, and those of ordinary skill in the art should be understood：Still
The specific embodiment of the present invention can be modified or equivalent, and any without departing from spirit and scope of the invention
