Description
Technical field
The present invention relates to a kind of power dispatching automation communication protocol techniques field, is driven based on event more particularly, to a kind of
The IEC104 stipulations analysis system and methods of mechanism.
Background technology
With the proposition and progressively deep, the especially extensive access of new forms of energy, it is desirable to which power system has of intelligent grid
The characteristics of standby real-time, reliability is high, data hold strong loading capability and high intelligence degree.Electric power scheduling automatization system conduct
The core of Operation of Electric Systems, the quality of data communication know the lifeblood of scheduling system intelligent degree.
IEC104 stipulations possess the advantage of uniqueness with its transmission medium as the Internet, used as the key of electric power dispatching system
Link, which is efficiently always the target that people pursue with stability.Existing IEC104 stipulations, generally using order, association
, the method for designing of proceduredriven, program detects main website with substation by the way of poll according to the pattern for designing one by one
Connection status, and in a fixed order, the various functions in 104 stipulations are realized successively.The order higher for priority level,
Need to be processed by the way of multithreading in the priority level for designing various orders in advance.
Existing IEC104 analytic techniques are suffered from the drawback that：
（1）Using order, proceduredriven mode, it is the execution sequence of the event and event fixed by programme-control, therefore
Very flexible, with user to interact difficulty big；
（2）Between various functions module, relatedness is strong, and the degree of coupling is high, and the exception of some function may affect other functions
Realize, uncontrollable factor is more in program operation, and debug difficult；
（3）When there is random, uncertain event to occur, need to start multithreading and processed.The introducing of a large amount of threads, meeting
Increase the expense of hardware memory, excessive thread is run simultaneously, or even program operation can be caused disorderly；
（4）In multithreading running, when several threads need to operate same object, thread latency is easily caused
Long or even deadlock, so as to affect real-time.
The content of the invention
The present invention mainly solves existing IEC104 resolution systems and have that very flexible, uncontrollable factor are more, debugging is difficult,
A kind of problem of operation disorder, thread latency length and deadlock, there is provided IEC104 stipulations solutions based on event-driven mechanism
