Decision-making technique.
Background technology
With the continuous development of extra-high voltage grid construction, interregional interconnection is more and more closer, and substation is as power grid core
Website, to the quick processing of its multiple compound contingency, fast quick-recovery normal device power transmission, more stringent requirements are proposed.Power grid event
The quick disposition of barrier there is an urgent need to using compared to former more abundant fault message, progress rapidly and accurately faulty equipment every
From, and the power transmission path of optimization is provided.
Currently, after identifying faulty equipment by accident analysis, selection restores power transmission path and relies primarily on dispatcher's
Operating experience, such way can be applicable in the case where minor scale power net simple fault.But for power grid multiple compound contingency
Speech, non-faulting equipment to be restored may more than one, and the recovery of each non-faulting equipment power grid can be generated compared with
Big influence, in addition lead to the problem of it is new, such as power flow transfer cause branch overload.Therefore, restore in power transmission path process, such as
The recovery sequence of what reasonable arrangement non-faulting equipment, on the one hand ensures the safe and stable operation of power grid, avoids insecurity
Occur again, on the other hand takes recovery power transmission path most short, the operating experience for relying solely on dispatcher judges, past
It is past to be difficult to obtain satisfactory result.
Invention content
It is an object of the invention to provide a kind of optimal power transmission path decision methods of the power grid of rule-based formula, and the present invention is in failure
When processing, the optimal path that restores electricity is formulated to dispatcher.
A kind of optimal power transmission path decision method of the power grid of rule-based formula, it is characterised in that carry out according to the following steps：
Step 1, breaker closing Cahn-Ingold-Prelog sequence rule when determining circuit power transmission；
Step 2, power transmission Cahn-Ingold-Prelog sequence rule when determining multi-line simultaneous faults；
Step 3 determines busbar or transformer fault power transmission rule；
Step 4 plans optimal power transmission path：Optimal power transmission path planning is carried out to complex fault according to above-mentioned rule.
A kind of optimal power transmission path decision method of the power grid of rule-based formula, it is characterised in that following steps：
Breaker closing Cahn-Ingold-Prelog sequence rule is when step 1 determines circuit power transmission：It first closes a floodgate far from fault point side；Or, if line
Road side is equipped with high-voltage shunt reactor, then closes a floodgate since offside；Or, if circuit side is power plant, opened from offside
Begin to close a floodgate.
Power transmission Cahn-Ingold-Prelog sequence rule is when step 2 determines multi-line simultaneous faults：The preferential power transmission of important interconnection or failure between province
The preferential power transmission of the preceding circuit in heavy condition.
Step 3 determines that busbar or transformer fault power transmission rule are：Busbar or transformer on site fault clearing and must be examined
Look into errorless rear power transmission.
Step 4 plans that optimal power transmission path is：According to above-mentioned steps one, Step 2: the rule progress described in step 3 is whole
Body power transmission path planning, to maximize guarantee power grid operation.
Description of the drawings
Fig. 1 is that the power transmission rule of the present invention forms flow chart.
Fig. 2 is the optimal power transmission path decision flow chart of the present invention.
Specific implementation mode
The technical solution of the present invention is further elaborated with specific implementation case below in conjunction with the accompanying drawings.
A kind of optimal power transmission path decision method of the power grid of rule-based formula, as shown in Figure 1, it is characterised in that press following step
It is rapid to carry out：

Step 3：Busbar or transformer fault power transmission rule are determined, for busbar or transformer fault, it is necessary to which scene excludes
Failure simultaneously checks errorless rear power transmission.
Step 4：Plan that optimal power transmission path is：According to above-mentioned steps one, Step 2: the rule progress described in step 3 is whole
Body power transmission path planning, to maximize guarantee power grid operation, detailed process is as shown in Figure 2：
(1) first determine whether that faulty equipment is that circuit or busbar or transformer are intended to busbar or transformer fault
On site fault clearing simultaneously checks errorless rear power transmission；
(2) for line fault, determine whether single-phase fault, if not single-phase fault, to arrive on site fault clearing
And check errorless rear power transmission；
(3) if line fault is single-phase fault, failure judgement equipment is a plurality of circuit or single line；
(4) a plurality of circuit is decomposed into multiple single lines power transmission in order, and power transmission path order planning strategy is：It is important between province
It is the first power transmission of heavy-haul line before interconnection or failure；Power transmission after common line.
