Fig. 2 is in the present invention, the corresponding relation exemplary plot of interval and primary equipment.
Embodiment
Below in conjunction with the drawings and specific embodiments, technology contents of the present invention is described in further detail.
Consider the interconnected characteristic of electrical equipment, all devices principle namely in an interval all interconnects, can electrical island be formed.The present invention first proposes a kind of method of the electrical equipment by being connected to locking equipment search around, and limits the border of respective electric equipment interval search.Be described as follows:
Usually, the equipment interval of electric system is made up of multiple interconnective equipment, and number is limited, can apply the method that " center part " add " boundary element " and be described interval.By guaranteeing that whole interval is separated with closed mode and overall grid structure by " boundary element ", then application ergodic algorithm finds in interval and safeguards facility information after all devices.
In one embodiment of the invention, corresponding searching method be electrical element model in D5000 system basis on realize.After in plant stand, equipment modeling completes, because electrical equipment all connects by connecting period, if so a given interval, the main equipment in corresponding interval is found according to given interval, after main equipment information creating gap model information, can find by connecting period the primary equipment be connected around this main equipment.Describe if the primary equipment searched meets interval, then can safeguard the interval information model that this primary equipment is corresponding.On the basis of topology, carry out searching for the correctness that can ensure to calculate, if the annexation between equipment is not right, then can not calculate within an interval from know-why.
As shown in Figure 1, the idiographic flow of all devices in the scouting interval is as follows:
1) information of main equipment corresponding in interval is obtained
In the present invention, primary equipment refers to transformer, bus, isolating switch, generator etc., main equipment refers to the primary equipment in selected interval, therefore concrete in main equipment corresponding device table primary equipment, the mode can mated by Chinese finds the information of corresponding primary equipment by given main equipment, as type, the information such as electric pressure and connection period of equipment.
2) all devices be connected is calculated by main equipment information
The primary equipment that main equipment is corresponding stores and connects period information, can be got by the 1st step, get connection period, then according to the computation rule of topology, search for the connection period information of all primary equipments by plant stand, connect at these connection period mating main equipment in period information.Can determine which equipment main equipment is connected in this way, then by the mode of recurrence, other connection device can be found out.Such as, main equipment A is connected to equipment B, C, and then by recursive fashion, equipment B is connected to equipment D, E etc., finally finds out the armamentarium in interval.
3) from configuration file, obtain the boundary definition pattern of main equipment
In the present invention, define search border to be realized by configuration file.By the corresponding relation of main equipment and plant stand, the voltage type (i.e. ceiling voltage) of corresponding plant stand can be determined, the configuration file used is determined by plant stand voltage type, the IV interval border corresponding to equipment of distinct device type, different electric pressure can be defined in configuration file, even reach designated equipment and carry out the special of border and define.From configuration file, obtain the boundary definition pattern of corresponding main equipment, the isolating switch boundary definition pattern as 500kV is as follows:
< circuit breaker voltage type=" 500kV " boundary types 1=" bus " frontier properties 1="-" boundary types 2=" circuit " frontier properties 2="+" boundary types 3=" isolating switch " frontier properties 3="-"/>
< circuit breaker voltage type=" 500kV " boundary types 1=" bus " frontier properties="-" boundary types 2=" transformer " frontier properties 2="-" boundary types 3=" isolating switch " frontier properties 3="-"/>
Illustrate: pattern comprises two groups, first group of boundary set is combined into that { bus < does not comprise >; Circuit < comprises >; Isolating switch < does not comprise >}; Second group of boundary set is combined into that { bus < does not comprise >; Transformer < does not comprise >; Isolating switch < does not comprise >}.
4) hunting zone is determined according to boundary definition pattern and topological connection relation
During other equipment that searching main equipment is connected, if the type of other equipment is in the set of the border of correspondence, then think that search arrives border.Determine whether edge device calculates in interval according to the principle comprising and do not comprise again.During other equipment that searching main equipment is connected, if the type of other equipment is not in the set of the border of correspondence, then continues down to search for, stop search until run into border.
5) in search procedure, the primary equipment information of association is stored
In the process of the primary equipment be associated by main equipment search, if the primary equipment found does not meet boundary definition pattern, then preserve the information of these primary equipments, for service intervals and primary equipment corresponding relation are prepared afterwards.To circulate in a manner described all intervals, then can calculate primary equipment corresponding to all intervals.
6) corresponding relation of interval and primary equipment is preserved in a database
After search terminates, in plant stand, related primary equipment information all preserves, again the information at interval is added in primary equipment information, preserve the corresponding relation of interval and primary equipment in a database, just can find all primary equipments under the correspondence of interval later easily.
Figure 2 shows that the corresponding relation exemplary plot of the interval that the present invention calculates and primary equipment.Under normal circumstances, the mode of connection of the equipment of a certain type of the plant stand under a certain voltage type is all fixing, only need to distinguish the border set that plant stand type, device type and electric pressure carry out configuration space, again by the method for topology calculate connection device, the primary equipment comprised in given interval just can be calculated.
Utilize the present invention, can improve the efficiency that interval data is safeguarded, the regional model former many people continuous working completed for several days was completed by people one time; Further, topological mechanism ensures the corresponding relation rationality of interval and primary equipment, thus guarantees the correctness of data.
Above the primary equipment maintaining method for Power SCADA system provided by the present invention is described in detail.For one of ordinary skill in the art, to any apparent change that it does under the prerequisite not deviating from connotation of the present invention, all by formation to infringement of patent right of the present invention, corresponding legal liabilities will be born.
