Description
Technical field
The invention belongs to the methods of the relay protection of power system fixed value adjusting of field of relay protection in power, especially relate to
And the relay protection fixed value setting calculation method based on Clustering.
Background technique
Traditional relay protection fixed value setting calculation method is all client/server (abbreviation C/S) frame using standard
Structure is realized, i.e., installs commercial data base server software in the server end of better performances, be responsible for the storage of data；User's
Client installs relay protection fixed value setting program.When setting procedure is run, as client from the commercial data of server end
Various data needed for reading adaptive setting and calculation of short-circuit current in library, and subsequent all adaptive setting work is all in visitor
Family end is completed, and client is after the completion of calculating task calculation result data write service device client database.Traditional adaptive setting
The framework of system such as Fig. 1, using the system of client/server (C/S) framework, there are the following problems:
(1) client process calculating speed is slow.Since calculating task is completed on the client, and client performance is limited,
The biggish task of calculation amount during adaptive setting, such as the tasks such as braning factor calculates, limiting value calculates, can be such that client falls into
Enter " no response " state, it is sometimes desirable to could calculate within several hours and finish, during which the work of user is not due to being available computer
It is greatly affected, the user experience of entire adjusting system is very poor.
(2) server and client are one-to-many relationships.One server is directly facing all clients, all numbers
According to interaction all by network implementations, when the data interaction that server end and client are frequent, especially work as multiple client
When interacting simultaneously with server, it be easy to cause the corresponding slow of database interface.And with the increase of client terminal quantity,
Due to database interface, the inquiry of commercial data base and write-in response speed can be slower and slower on server.
(3) server is merely responsible for data management.Common server possesses in more CPU and high speed compared to client
It deposits, computing capability outclass client workstation.And the relay protection fixed value setting of traditional client/server framework calculates
System, which only is used to server to install commercial data base, does data management work, suffers the hardware resource with superior calculated performance
It has arrived and has left unused, caused the huge waste of server hardware performance.
(4) what existing adjusting software server end used is all windows operating system, is easy by virus and wooden horse
It threatens, and then causes the safety and reliability for protecting fixed value adjusting system that can not ensure.
Summary of the invention
The technical problems to be solved by the invention are to provide for the defects of aforementioned background art and deficiency based on collection
The relay protection fixed value setting calculation method of group's technology.Its object is to improve the calculating speed of relay protection fixed value setting calculating
Degree, higher efficiency utilize server end hardware resource, improve the operating experience of user.
To realize the above-mentioned technical purpose, the technical scheme adopted by the invention is as follows: the relay protection constant value based on Clustering
The computation-intensive task being related to during fixed value adjusting is transferred to computing cluster to be responsible for completion by synchronizing calculation method, can be with
Significantly improve the calculating speed of relay protection fixed value setting, it is characterised in that the following steps are included:
(1) computing cluster and client being made of multiple servers using the relay protection fixed value setting system of this method
Work station two parts it is main at；Computing cluster is responsible for completing all computation-intensive tasks, the task schedule of computing cluster, node pipe
Reason, calculated result processing work are automatically performed by the cluster management program operated on computing cluster server；
(2) computing cluster is responsible for two class of computation-intensive task dividable completed, i.e. the whole network scan task and client mentions
Friendship task；
(3) the whole network scan task refers to the cluster management program in computing cluster in grid operation mode or power grid mould
The computation-intensive task of automatic trigger when type changes, the computation-intensive task of the automatic trigger include limiting value meter
It calculates, braning factor calculates；Its distinguishing feature is scanned for primary equipment all in adjusting target grid.
(4) client workstation is user and the terminal that relay protection fixed value setting system interacts, and is equipped with adjusting
Client software is calculated, it can be achieved that pre-processing to user's operation；If user's operation belongs to computation-intensive task, adjusting
Software for calculation first automatically inquire database in the whole network scan task as a result, if inquiring correlation calculation result, terminate the meter
Calculate process；If not inquiring calculated result, automatically generates client and submit task and submit to computing cluster, then certainly
Dynamic cyclic query calculated result simultaneously completes subsequent calculating；Client submits task to be characterized in for part primary equipment in power grid
Calculating task.
(5) cluster management program in computing cluster is responsible for after finding new calculating task request, by server cluster
In each server node loading condition calculating task is dynamically distributed automatically；It is close that the server of computing cluster is equipped with calculating
The calculation procedure of collection type task, the calculation procedure of the computation-intensive task include that limiting value calculates, braning factor calculates；Root
It is calculated according to the task call relevant calculation program of distribution and feeds back calculated result；Cluster management program can be by different server
Analysis result be uniformly processed.
Further, the cluster management program meeting automatic election generates unique command node in computing cluster, commander
Node is responsible for task distribution, the processing work of calculate node Stateful Inspection, calculated result；Server as command node occurs different
Chang Hou, management and computing function are replaced by the normal server node of another mesa-shaped state for re-electing generation in a group of planes automatically
Command node originally.
Further, the cluster management program and intensive calculations program support cross operating system operation；The operation system
System includes Windows, Linux, Unix, domestic kylin secure operating system, domestic loses in thought secure operating system.
Further, the computing cluster can realize the redundant configuration of computing resource, the calculating task meeting of abnormal server
In Autonomic Migration Framework to normal server, system, which only has a server normal operation, can also complete all calculating tasks；Entirely
The normal calculating service of system is not influenced by separate unit or multiple servers node failure；Whether each server node, which participates in, is counted
Calculation task can be by user setting.
Using the relay protection fixed value setting calculation method described in the invention based on Clustering, by calculating task
Processing has been put into server end, and uses Clustering and carry out being uniformly coordinated pipe to server end Servers-all node
Reason, the hardware resource that server end is utilized significantly more efficient compared to traditional user terminal/server framework reduce client
The work load and network burden of work station improve the overall calculation efficiency of adaptive setting system, improve user experience, will
The computation-intensive task being related to during fixed value adjusting transfers to computing cluster to be responsible for completion, can significantly improve relay protection
The calculating speed of fixed value adjusting.
