Description
Technical field
The invention belongs to the Power System Analysis field, the present invention relates to a kind of more precisely based on the multi-mode DTS interconnected method of trend coupling with the computation model splicing.
Background technology
Along with the expansion of electrical network scale, when being improved, resisting the single failure ability at grid supply quality and be enhanced, cascading failure occurs, cause the potential threat of electric grid large area power cut also to increase greatly.It is more much bigger than in the past to the impact of each regional power grid that catastrophe failure takes place under the interconnected power grid service condition, and the cooperation of scheduling at different levels is vital.As the strong instrument of dispatcher training emulation, how to utilize the DTS system to realize that Combined anti-accident maneuver becomes dispatching centers at different levels questions of common interest.
Use at present the DTS system to carry out Combined anti-accident maneuver and substantially can be divided into two kinds of thinkings: centralized is unified emulation and distributed networking emulation.Centralized unified simulating scheme is that the electrical network with the units of taking part in a performance at different levels all carries out modeling, sets up one and satisfies the unified integrated model of the whole network that Combined anti-accident maneuver requires, and scheduling at different levels are all carried out Combined anti-accident maneuver on this integrated model; Distributed networking emulation is the resource that makes full use of the DTS system that has now built up, and DTS system interconnect at different levels are got up.The exchange of border profile data and event realizes the mutual of DTS system of the superior and the subordinate in the employing manoeuvre process.
Document 2 " based on the DTS of internet associating Training Simulation System " (relay 2006 the 34th the 2nd phase of volume the 70th page) has disclosed a kind of thought with " principal and subordinate's splitting-up method " and has applied to distributed power flow algorithm in the interconnected analysis of power transmission network.This algorithm is transferred side-looking with ground in calculating be the broad sense load side that province transfers side; Transfer side-looking to transfer the broad sense power end of side with economizing with being.
Above-mentioned thought is applied in the actual networking process, and province and district is transferred in the manoeuvre process real-time, interactive separately trend value and the Action Events at critical point, realize province and district trend and equipment state synchronously.Economize and transfer the usually value take the 220kV main transformer as the critical point, follow the tracks of the variation that the main transformer trend is transferred on ground; Ground is transferred usually take 220kV border interconnection as the critical point, follows the tracks of and economizes the power flow changing of transferring interconnection, and the operations such as switch tool are carried out real-time interaction as event.This pattern also is the comparatively general province's ground networking pattern of present domestic use.
Use this algorithm to have following problem: 1. to transfer usually not comprise External network model information in the modeling, but simply become generator to process with the border interconnection is equivalent, therefore can't truly reflect when outer net mode changes to Intranet, particularly to the impact on border; 2. economize each self-modeling of ground, affected by model bigger for the trend result in the networking process, particularly is subjected to the branch road effect of parameters, causes province's ground lap calculation of tidal current inconsistent.
Document 3 " based on the interconnection system distributed tidal current computing method of computation model splicing " (Chinese patent application CN200710191542.1) has disclosed a kind of interconnection system distributed tidal current computing method based on the computation model splicing.This algorithm does not have any outer Coordinating And Iterating Methods yet and calculates between subnet, thereby has avoided complicated algorithm organization pattern, possesses simultaneously and the on all four result of calculation of the integrated calculating of the whole network.This algorithm all is spliced to major network with the computation model of each subnet, carries out the calculating of the whole network trend in the major network side, then result of calculation is returned to each subnet.
As above-mentioned algorithm is directly applied in the actual networked system, along with the subnet quantity that participates in networking increases, the calculation scale of major network and amount of calculation are all in continuous increase, and speed and convergence that the major network trend is calculated have considerable influence.Therefore, characteristics at the actual motion system, need improve this algorithm, major network and should be relations on an equal basis in the networking process from net, major network and all carry out the transmission of computation model file from net is no longer spliced whole models by major network and calculates and the result returns, but major network and separately required electric network model is spliced from net, carry out trend calculating to splicing the back model separately, and result of calculation is written back in the local corresponding device.

In the present invention, disclosed multi-mode implementation method and the multimodal real-time changing method that trend is mated and computation model splices in the networking process.For realizing economizing the different demands of ground in the interconnected process to the networking pattern, the present invention discloses a kind of multimodal DTS interconnected method, this method can be supported critical point trend match pattern, can support computation model splicing pattern again, this method is monitored in real time to the networking pattern setting of each subsystem of participation networking simultaneously, is provided with according to different patterns and adopts different processing modes.
Multimodal implementation method step is as follows:
51) add the computation model export function in the trend module, after each network topology, computation model is exported to file and leave under the assigned catalogue, and stamp markers for this document; Computation model is spliced function embed in the trend module, trend can be spliced calculating to the computation model that receives as required automatically.
52) interconnected interprocess communication carries out real-time supervision to process and the result of trend calculating, if find to have under the computation model storing directory computation model file of renewal, then at once this computation model file is read and sent to other networking subsystems.
53) the interconnected interprocess communication of transferring according to step 1) in definition, periodically obtaining from trend needs readjust the distribution the trend result who send and need to transfer the facility information that obtain trend from economizing toward economizing, and sends to province and transfers; Economize to transfer the message that obtains trend for the needs that receive, from trend, the trend value of relevant device taken out at once and accent with returning to, and readjust the distribution the trend message that the requirement sent writes for ground, then hand to trend and process.
54) the trend computing module is before Load Flow, earlier trend message and the computation model message of the subsystems that receives are judged, if certain subsystem is the computation model Splicing model, then the computation model message to this subsystem of receiving splices calculating, abandons the trend message of this subsystem; If be the trend match pattern, then directly process the trend message of this subsystem, to the exerting oneself/load and revise of this locality, abandon the computation model message of this subnet.
Can switch in real time the networking pattern of each subnet in the networking process, the variation of each subsystem networking pattern of system's monitoring in real time also adopts corresponding mode to calculate.
Transfer the interconnected real-time changing method of networking pattern that illustrates to economize to transfer with two ground below.Fig. 1 is the rough schematic view of province's zone network modeling, has also represented the general modeling pattern of power system application software of domestic each control centre, and Fig. 1 (a) transfers the modeling schematic diagram for economizing, and wherein left-hand component belongs to regional A, and right-hand component belongs to regional B, l
3Be the interconnection between the regional AB, the 220kV main transformer in the factory station is equivalent one-tenth load usually; Fig. 1 (b), Fig. 1 (c) are the respectively corresponding modeling schematic diagram of regional A, regional B, common interlocal interconnection is processed as equivalent generator, and has comprised the following complete modeling of 220kV main transformer.
Suppose that networking starting stage two places accent all adopts the trend match pattern, the implementation of this moment is as follows:
A) transfer A and ground to transfer B periodically will need the S that sends
A, S
BThe l of trend is obtained in main transformer high-pressure side trend value, requirement
3The latest calculation model file of this locality that equivalent generator information, trend module derive sends to province and transfers.After message was received in province's transfer, it was for subsequent use earlier main transformer trend value to be handed to the trend module; The computation model packet parsing is become file and puts into assigned catalogue, for file is stamped markers; Transfer requirement to obtain l for ground
3The message of trend obtains interconnection trend value and returns to respectively and transfers from the trend module; Economize simultaneously and transfer also that this locality is up-to-date computation model message file to transfer A and ground to transfer B with sending to.
B) the trend module is before carrying out trend calculating, the A that participates in networking, the networking pattern that B is transferred are detected, be the trend match pattern this moment, transfer main transformer high-pressure side trend value to write in the local system on the ground that receives, revise the trend value of two duty values such as main transformer, then do not process for the computation model file that ground is transferred.
Suppose and transfer A to switch to the computation model Splicing model on ground, ground transfers B still to keep the trend match pattern, and the implementation of this moment is as follows:
C) reception of interconnected message and process still as the step of aforementioned province accent a) shown in.
D) the trend module is before carrying out trend calculating, the A that participates in networking, the networking pattern that B ground is transferred are detected, this moment, regional A switched to computation model splicing pattern, trend is calculated the latest calculation model file that reads the A that receives, splice with the local latest calculation model file of deriving before, splice point is chosen as the main transformer high-pressure side automatically.With the splice point is the boundary, economizes the duty values of transferring such as 220kV main transformer and is cut; Ground transfers the above all devices in 220kV main transformer high-pressure side to be cut.Spliced result economizes the following equipment of 220kV of stealthily substituting and having contained the above all devices of local 220kV and regional A.Area B still is the trend match pattern, according to abovementioned steps b) directly to the station S of factory
BThe duty value that waits revise.Spliced province transfers electric network model as shown in Figure 2.Carry out trend with this spliced model and calculate, and calculate finish after with S
AThe station owner of factory becomes high-pressure side trend result and is written back to Fig. 1 and economizes and transfer S
AThe station owner of factory becomes etc. in the duty value.
More than economize to transfer side to illustrate that multi-mode realizes and real-time changing method as example, the implementation of transferring side on ground is similarly, transfers over the ground below the implementation of side to briefly explain:
Only normally transferring in interconnected process need to transfer in row interconnected with province, and does not directly carry out data interaction between other areas, in Fig. 1 regional A as example, the border interconnection l between the required and regional B
3Information directly from economize to transfer obtaining, need not has data interaction with regional B again.
Suppose that initial networking pattern is a critical point trend match pattern between regional A and the province's accent, performing step is:
The transmission of a) transferring trend message, computation model message and processing procedure etc. transfer step a) identical with aforesaid province.
B) owing to adopting the trend match pattern with economizing accent, ground accent trend module directly will be economized when carrying out trend calculating and transfer the trend message that returns to process the l in the revised version zone network
3The trend value of equivalent generator.
Become the computation model splicing with economizing the networking mode switch of transferring, then Ci Shi performing step is as follows:
C) between the province ground reception of message and process still as the step of transferring aforementionedly a) shown in.
D) economize the pattern of transferring this moment and switched to the computation model Splicing model, ground is transferred no longer to process to economize and is transferred the trend message that returns, but before trend is calculated, resolve economizing the computation model of transferring, to splice with the local computing model, splice point still is chosen as 220kV main transformer high-pressure side.At this moment, the above all devices of 220kV is cut in the ground mode transfer type, economizing the duty values of transferring such as 220kV main transformer is cut, finally be spliced into a ground and transfer the computation model of the following electric network model of 220kV+province's mode transfer type, as shown in Figure 3, on this model, carry out trend and calculate, and the result of calculation of the above equipment of 220kV that is cut in the computation process is written back on the corresponding device of ground mode transfer type.
