Abstract
The invention discloses a work method of a failure recovery processing module. The work method is suitable for the failure recovery processing module of a load transfer scheme generating system operating when the power side of a power distribution network breaks down. By the adoption of the work method, a power restoration scheme of an equivalent failure feeder line can be generated according to the failure equivalence and a feeder line failure recovery problem provided by an in-station load transfer scheme generating module.
Description
Technical field
The present invention relates to a kind of method of work of Petri Nets module, the Petri Nets module of load transfer plan scheme generation system when being applicable to power distribution network source-side fault.
Background technology
Power supply reliability is the leading indicator of examination electric power system quality.Improving power supply reliability is one of core drive of intelligent grid construction, particularly intelligent power distribution network construction.In the construction of intelligent distribution network, practical along with feeder automation function, electrical power distribution automatization system effectively shorten power distribution network break down after dead electricity time of non-faulting section, electrical power distribution automatization system becomes the important means improving distribution network reliability.
Feeder automation is one of Core Feature of electrical power distribution automatization system, can realize the fault detect under power distribution network accident condition, fault isolation and service restoration function.Wherein power distribution network service restoration is a multi-target non-linear restricted problem.In this way to solve the problem, intelligent algorithm and heuristic search algorithm are the most general, and many documents conduct in-depth research these two kinds of methods.Although intelligent algorithm can form more excellent recovery scheme, iterations is many, and calculated amount is large, cannot meet the requirement of distribution network reliability.And heuristic search search speed is fast, fault recovery can be realized rapidly.In the engineering of reality, in order to improve the formation speed of service restoration scheme further, the general heuristic search adopting simplification, realizes within 5 ~ 10s, generate service restoration scheme.
It is many that the source-side fault such as substation bus bar decompression, main transformer fault relate to customer interrupted, and coverage is large, although frequency is few, is subject to the attention of power department equally., there is source-side fault in peak times of power consumption, depend merely on the inner margin capacity of transformer station and often cannot recover all loads in growing along with power load.Along with the raising of feeder line contact rate, realizing large-scale load safe transfer by feeder line outside coupling switch becomes possibility to tackle transformer station's not enough problem of inner margin capacity.
Compared with the service restoration problem after feeder fault, the region involved by source-side fault load transfer plan problem is larger.Because the feeder line that every bar bus connects is generally at 8 ~ 12, source-side fault load transfer plan is equivalent to the superposition of multiple feeder fault service restoration problem.If source-side fault load transfer plan problem is also regarded as a multi-target non-linear restricted problem, direct employing intelligent algorithm and heuristic search algorithm generate its load transfer plan scheme, then the dimension of problem becomes geometric series to rise with search volume, makes generation fast very difficult.
Summary of the invention
The object of the invention is the defect overcoming prior art, a kind of method of work of Petri Nets module is provided, the Petri Nets module of load transfer plan scheme generation system when being applicable to power distribution network source-side fault, the feeder fault that can provide according to fault equivalence and station internal loading transfer scheme generation module recovers problem, generates the service restoration scheme of equivalent fault feeder line.
The technical scheme realizing above-mentioned purpose is: a kind of method of work of Petri Nets module, and described Petri Nets module is connected with fault equivalence and internal loading shift module of standing, and this method of work comprises the following steps:
S1, described Petri Nets module obtains pending feeder fault quantity and the fault recovery district of correspondence from described fault equivalence and station internal loading shift module;
S2, whether timing inquiry has needs new feeder fault to be processed, if so, then carries out step S3; If not, then after waiting for 0.1 second, step S1 is returned;
S3, first suspends existing Petri Nets, upgrades the electriferous state turning power supply source in each fault recovery district; Then again add up and turn power supply source data involved by each fault recovery district;
S4, judged whether share turn power supply source, if so, then carry out step S5; If not, then step S6 is carried out;
S5, has that to share the several substance faults turning power supply source be multiple failure, then multiple failure public is turned power supply source decoupling zero equivalence and become multiple and turn power supply source, thus realize multiple failure to change into multiple substance fault;
S6, adopts heuristic mode search to generate feeder fault and to restore electricity scheme;
S7, judges whether that untreated complete feeder fault recovery scheme generates, if so, returns step S6; If not, step S8 is carried out;
S8, judges whether feeder fault is all disposed, and if so, directly terminates; If not, then step S1 is returned.
The method of work of above-mentioned a kind of Petri Nets module, it is characterized in that, in described step S5, the public multiple decoupling method turning power supply source of power supply source decoupling zero equivalence one-tenth that turns of multiple failure be: share and turn power supply source by margin capacity vacancy proportional allocations to corresponding fault recovery district, the rear all feeder faults of process are all substance faults.
The method of work of Petri Nets module of the present invention, beneficial effect is compared with prior art: the Petri Nets module of load transfer plan scheme generation system when being applicable to power distribution network source-side fault, the feeder fault that can provide according to fault equivalence and station internal loading transfer scheme generation module recovers problem, generates the service restoration scheme of equivalent fault feeder line.
