If S110, load importance are more than pre-set threshold value, protection level increase, corresponding cooperation time increase is preset Duration, wherein, protection level is less than 3.
The pre-set threshold value is also user's sets itself, and the embodiment of the present invention is not particularly limited it, if load weight The property wanted is more than pre-set threshold value, then protection level increase, corresponding cooperation time increase preset duration.
In existing distribution network protection, the problem of generally laying particular stress on the safe operation for considering system side, and ignore user side, protection Level is single.Compared with existing distribution network protection, adjusted an embodiment of the present invention provides a kind of ground county in fixed setting method, first Switching network topological diagram is obtained in real time, then by the mobile agent access target switching node, collects all of its neighbor switching node Configuration protection information, the load importance of all of its neighbor switching node is calculated based on configuration protection information, if last load Importance is more than pre-set threshold value, then protects level increase, corresponding cooperation time increase preset duration.The ground county adjustment of the present invention Fixed setting method is a kind of expansible protection level, can will protection boundary downstream extend to responsible consumer, upwards with Substation transformer coordinates, and forms a set of definite value relatively-stationary on the basis of substation transformer, setting principle is enriched, examined The power demand of user side is considered, has adapted to intelligent network distribution construction, it is single to alleviate existing distribution network protection setting principle, lays particular stress on and considers System side safe operation, and ignore the technical problem of user side.
First the distribution of protection scheme level is introduced below:
As shown in Fig. 2, this is one coordinates signal by a three-level for coordinating border to extend to feeder line downstream panel switches Figure.This pattern is mainly considered to exit the snap action section of feeder switch 2., reserves one and coordinates the time differential to give down 3. the panel switches of trip, are not in thus the situation that level trips that jumps when downstream fault.Specifically, 3. downstream that ought be occurs During failure, ta3It is small, then 3. user's panel switches first trip, coordinate time feeder switch 2. can just trip by one, avoid Jump when downstream fault the situation of level tripping.
But under present circumstances, if it is the problem that electric system needs to weigh to exit instantaneous section, it is contemplated that system Stabilization safe operation, and the fault-resistant impact capacity of equipment particularly transformer, if exiting should carry out according to different situations Selection.As shown in Fig. 2, generally guarding at present, take still be two-stage Graded coordination system, as time ruler mark blackboard divides in figure Shown, there are t at this timea2=ta30.When using this ta2=ta30Situation when, when downstream fault 3., because ta2= ta30, so 2. 3. feeder switch trips at the same time with user's panel switches, here it is the situation of jump level tripping.Used in the present invention Scheme be two-stage Graded coordination scheme.
Here the characteristics of in order to using the mobile agent, define corresponding electrical network feature again.It is real in electric network protection An existing protection first has to accurately judge faulty equipment, and equipment is done as minimum unit and is cut off from power grid.But due to Power grid can not often distinguish substation feeder and the protection of downstream user side as the afterbody of power grid, Preservation tactics It can only be cut off with tripping at the same time after failure as same fault object.And opened for user side equipped with breaker and accordingly In the case of closing and protecting, then protection cooperation border is needed to extend downwardly, and feeder line also reserves certain adapted space, with shape Layered level mating protection relation, carrys out isolated fault with the fault outage region of minimum level and minimum.How key is to electricity Net topology structure forms the guarantor that information can flexibly be integrated by graphic characteristics with switchgear distribution and related protective nature analysis Shield scheme.
As shown in figure 3, for the short circuit of radius of electricity supply, its protection cooperation should adopt traditional protection configuration, and (level that jumps is jumped Lock), i.e., instantaneous one section of feeder switch is retained, coordinate border so far.And for radius of electricity supply length circuit, then It is considered as protecting with downstream branch and is engaged, reserves level-one or two-stage cooperation is differential, form complete matching relationship.To reach The purpose of failure is precisely cut off during failure as far as possible.Certain this Graded coordination is also contemplated that the economic benefit of user, and system is set Standby horizontal, the demand of institute with specific load etc., integrates and judges.
Therefore the propulsion on protection border how is carried out, then is transmitted by the comprehensive analysis and order of information.If from information Processing and the angle integrated, it is believed that be that level framework is carried out by topological analysis and relevant relaying configuration grade, then By possessing the point of branch's relaying configuration, to it according to its significance level, can be divided by its load character, then shape Into weighted value, the level for determining protection by these weighted values divides.Specifically released again in the form of network information Node distribution Upper figure.
County adjusts the overall process of fixed setting method and is described the above over the ground, below to being directed to Particular content describes in detail.
Alternatively, with reference to figure 4, collecting the configuration protection information of all of its neighbor switching node includes:
S401, judge target switch node go out whether the number of degrees are 0;
As shown in Fig. 5 (a), 5 (b), 5 (c), the TE for being distributed in each switch, it is straight to preserve this switching node in database Connect connected using this node as starting point, the order adjoining list using destination node as direction point.Such as in Fig. 5, node number is 4 Node, there is the destination node of two connections, is respectively 2 nodes and 3 nodes.The information in Ri rows can be represented with bit vector, it is right Only store and control oneself relevant node connection figure in each TE, so each node only corresponds to a row vector.First is section Period, second are the branch's number (spending) that is connected, and the 3rd is connected specific node number.Using in JAVA class libraries Java.util bags create a vector, there is three-dimensional, are the vectorial reality that an actual connecting node is each dimension again in the third dimension Example object, its dimension are determined by the degree parameter of the second dimension.When the network structure of system changes, i.e., when this switch When the corresponding connection number of degrees and connecting node change, when often connecting a new node or reducing by a node, it will make The number of degrees increase one or subtract one, match with network real-time architecture.
For 5 (a), when target switch node is 3, go out the number of degrees for 2, it is corresponding to be switching node 1 and open Artis 3;When target switch node is 2, it is 4 to go out the number of degrees, and corresponding is switching node 1, switching node 3, joint Point 4 and switching node 5 (i.e. lower floor's switching node).
If S402, go out the number of degrees for 0, terminate and access;
If S403, go out the number of degrees be 0, it is determined that the lower floor switching node direct-connected with target switch node;
Illustrated so that target switch node is 3 as an example, the lower floor switching node direct-connected with target switch node is respectively Switching node 1 and switching node 4.
S404, using the lower floor switching node direct-connected with target switch node as all of its neighbor switching node;
All of its neighbor switching node using switching node 1 and switching node 4 as target switch node 3.
S405, the configuration protection information for collecting all of its neighbor switching node.
Specifically, configuration protection information is user's setting, there is configuration protection then to put 1, be configured without protection and then set to 0.Receive Collect the configuration protection information of switching node 1 and switching node 4.
Alternatively, with reference to figure 6, the load importance of all of its neighbor switching node is calculated based on configuration protection information to be included:
S601, be that all of its neighbor switching node assigns weights;
Specifically, the imparting of weights has user independently to set.
S602, calculate all of its neighbor switching node weights and;
S603, using the weights of all of its neighbor switching node and the load importance as all of its neighbor switching node.
If load importance is more than pre-set threshold value, protection level increase, the corresponding cooperation time increases preset duration, Wherein, level is protected to be less than 3.
As exceeded pre-set threshold value, then its upper strata protective layer level rises load importance, corresponding to coordinate the time to add Δ T.Specifically , as shown in Fig. 5 (a), for target switch node 3, (load importance is more than for its last requirement for meeting configuration protection Pre-set threshold value), then, protection level adds 1 grade, and upper strata protection level (i.e. 2) is corresponding to coordinate time increase preset duration.
Alternatively, the mobile agent includes id information, and after completion task, the mobile agent disappears the mobile agent automatically.
In order to meet the analysis requirement of real-time, after the analysis agent positioned at host determines failure switch, it will be produced Raw the mobile agent, in order to avoid it searches for the time of destination server, the analysis agent of host provides the target of dynamic agent The address (ID) of server, the setting in this path can be registered realization in the mobile agent manager.And in this, as The ID (unique mark) of this task of the mobile agent.Operation content (OPERATION) is write in the content of the mobile agent (content).After the mobile agent reaches destination server, according to the mission requirements of itself, using local data resource into Row corresponding analysis.Need exist for knowing present node be connected directly with each branch switch, then using local data storehouse, by number According to the satisfactory each point transmission trip signal of content in storehouse.Here each TE is required to have the number being connected directly with this node According to library storage resource, direct relation occurs because only being switched with itself, takes limited memory source.When this task is complete Cheng Hou, the information that the mobile agent need to only be successfully completed to one work of host loopback where manager itself, manager will This task is unregistered according to ID, this mobile agent disappears automatically, by the Garbage Collector of host and each TE by its time Receive, discharge its internal resource utilized.ID therein is the unique mark of a mobile agent, whole from its generation to disappearing In a life cycle, no matter it is moved to the arbitrary point in network, it can all register this mark, and area is carried out with other agent Point.Here it is also pointed out that be either host system database, or the related network topology database of switch of each TE, All belong to permanent data base (persistent), can refresh in real time because of the change of network structure, but not disappear.Divide with more than The mobile agent (instant) property of division life is different.
It is to be collected by the mobile agent according to system topology information that Zhong Di of embodiment of the present invention counties, which adjust fixed setting method, Analysis is drawn, therefore the strategy provided is expansible protection level, and original protection boundary is downstream extended to important use Family, coordinates with substation transformer upwards, forms a set of definite value relatively-stationary on the basis of substation transformer;It is aided with the same time Demarcation switch and the intermediate switch of long transmission line and its corresponding protection section are engaged, and overcome original protection scheme to depend on line Road length, is influenced not ensureing to coordinate the characteristics of selective by the method for operation.
Embodiment two:
