Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1, the power distribution network large-area power-cuts recovery technology containing distributed power source of the present invention, comprises following several step:
One, large-area power-cuts identification: can identify whether power distribution network there occurs large area blackout quickly and accurately;
Large-area power-cuts be identified by two judgements add one verification mode identify, as shown in Figure 2:
(1), large-area power-cuts identification judges: comprise busbar voltage decompression and judge and the judgement of circuit breaker current zero;
(2), large-area power-cuts verification: whether the controller switching equipment electric current detecting the drive of respective bus bars downstream makes zero, and verification adopts percents to judge.Specifically, exactly this all controller switching equipment in bus downstream is searched for entirely, detect the electric current of the switch of all devices, and all testing results are generated statistics ratio value, zero ratio is more than 80%, and verification is passed through, meet the entry condition shown in Fig. 1, enter step 2; 30% to 60% is suspicious, now notifies that user has the possibility of large area dead electricity herein, and indicating probability value, be confirmed whether to continue to analyze by user, if continued, then enter step 2 below, if do not continued, do not start; Less than 30%, then do not pass through, namely do not meet the entry condition shown in Fig. 1.
Two, turn confession region effectively to isolate: in order to ensure the fail safe that distribution large-area power-cuts recovers, after recognizing large-area power-cuts, the very first time is needed effectively to isolate needing the region turning confession, ensure Supply Security, by all wire-outgoing breaker separating brakes of bus downstream associative, ensure to turn the obvious cut-off point for region, guarantee the Supply Security in territory, area to be transferred.
Three, turn for load Analysis: in conjunction with network topology, load attribute, distributed power source attribute, Power supply ability many factors, analyze needing the load turning confession, Main Analysis load character (important level, duplicate supply user), payload, the short-term load (duty) rule of development, and according to analysis result, load classification is sorted, tentatively obtain the optimal reconfiguration sequence of steps containing distributed power source, prepare optimal reconfiguration.
Four, containing the optimal reconfiguration of distributed power source: complete turning for after load Analysis of previous step, start to carry out load optimal reconstruct, reconstruct is optimized so that load rejection is minimum for target.Utilize the access of distributed power source, expand the power scheduling ability of power distribution network, improve large-area power-cuts recovery capability, thus ensure that power distribution network large-area power-cuts full recovery at short notice becomes possibility, propose in the power distribution network large-area power-cuts recovery containing distributed power source simultaneously, the startup principle of distributed power source, the generation of method of calibration and step strategy, ensures power supply capacity and the power supply quality of power distribution network.
When carrying out the optimal reconfiguration containing distributed power source, mainly follow following principle, as shown in Figure 3:
(1) main power source supply power mode, is paid the utmost attention to, whether the power supply total amount that first calculating main power source provides can satisfy the demand and turn a demand for confession load, when calculating, in order to avoid producing useless amount of calculation, need to consider certain redundancy capacity, generally get the redundancy nargin of 0.2, namely calculate 80% of the total amount that main power source provides and whether can meet the demand turned for load.If can satisfy the demands, then first start with main electric network source as power supply point, with the minimum recovery and optimization reconstruction calculations for target of load rejection, and form initial optimization reconfiguration scheme, due to supply path restriction, even if amount of power supply can meet the demands, also the situation that cannot meet power demands may be there is, therefore, when generating initial optimal reconfiguration scheme, if cannot power demands be met, then need to recalculate;
(2), when main power source cannot satisfy the demands, then consider that the optimal reconfiguration that the power supply possessing black start-up ability participates in calculates, be still optimized reconstruct so that load rejection is minimum for target, generate new optimal reconfiguration numerical procedure; Then, then calculate the distributed power source not possessing black start-up ability, the distributed power source not possessing black starting-up condition is counted in reconfiguration scheme according to access point one by one, and carry out corrigendum calculating according to the Power supply ability of supplementing into, generate new scheme.
(3), when distributed power source participates in recovering, following principle is followed in its startup:
When a, distributed power source are powered to the isolated island formed after network reconfiguration, need the black starting-up principle considering distributed power source:
Load restoration needs to recover one by one by 0 according to the power supply capacity of distributed power source, therefore when recovering the isolated island that distributed power source is powered separately, needs first all to be pulled open by on-load switch, enters again and recover one by one after waiting for distributed power source startup;
During distributed power source black starting-up, the power supply possessing black start-up ability needs first to start, if possess multiple distributed power source possessing black start-up ability jointly to recover, test according to the demand of distributed power source paired running, if can paired running, then put into and can put into same isolated island and run, if verification is not passed through, then split into multiple isolated island and recover;
Do not possess other distributed power sources of black start-up ability, and need the load of recovery, according to power supply capacity, the conditions such as voltage fluctuation limit value calculate recovery capability, ensure power supply quality and power supply capacity, generate the sequence of operation that can meet power demands, operate.
The supply network of b, non-islet operation: if it is grid-connected to there is distributed power source, first main power source is recovered, main power source recovery is carried out again after the load excision that cannot drive according to power supply capacity, then that distributed power source is grid-connected, according to power grid condition, verify grid-connected ability, after verification, generate grid-connected operating procedure, after distributed power source is grid-connected, to power supply capacity be expanded, finally according to newly-increased power supply capacity, the load restoration excised before be powered again.
Five, dynamic conditioning operation: after all operations schemes generation, the executable operations stage will be entered, straighforward operation is carried out one by one by power distribution automation main website according to the sequence of steps generated, in remote control process, may run into the remote control failure because a variety of causes causes, remote control unsuccessfully will cause subsequent operation possibly cannot normally carry out, therefore when there is remote control tripping, need to adopt dynamic conditioning operation, dynamic conditioning is carried out to ensuing operation.If now carry out the whole network reconstruction calculations again, may by what cause the switch operated again to carry out to operate, thus cause endless loop, optimum solution path cannot be obtained, situation simultaneously also in order to avoid causing user repeatedly to have a power failure, therefore the switch operated and the region that restored electricity is needed to lock, after again the switch of remote control tripping being marked, finally re-start secondary network reconstruct to not recovering region again, when carrying out secondary network reconstruct, take network reconfiguration among a small circle as far as possible, and with the minimum scheme for target of load rejection, the step obtained can be operated, the time requirement ensureing computational speed simultaneously and restore electricity.
By the execution of above steps, the large-area power-cuts that the present invention proposes containing distributed power source recovers, and further, in order to perfect disposed of in its entirety flow process, the invention allows for the optimizing operating mode recovered part after failture evacuation, being elaborated as follows.
Six, optimizing operating mode recovers: system completes after large-area power-cuts recovers, and because now operational mode is transient state mode, thus whether system starts constantly to detect large area blackout and eliminate, and whether original bus restores electricity ability.Once detect that original bussed supply ability is recovered, then carry out operational mode recovery operation, according to the system optimal operational mode recorded before large-area power-cuts, again according to development trend and the power supply capacity of power supply, the operability COMPREHENSIVE CALCULATING of switch of existing load, generating run mode recovery policy, electrical power distribution automatization system is used to carry out straighforward operation, thus the operational mode recovered before fault generation, the optimization completing operational mode recovers, and ensures the operation with closed ring of large-area power-cuts process.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
