多大な計算時間が必要になる等の問題がある。2. Description of the Related Art As a method of determining a load accommodation mode of a distribution system, a sequential solution method using heuristics as proposed in Japanese Patent Laid-Open No. 63-310333 is practically used as software for a computer system. In the iterative solution method, since the feeder allocation process to each node is multistage in the process of determining the flexible mode, there is a problem that a large amount of calculation time is required especially when the target is large.

要である。Therefore, as described in Japanese Patent Application Laid-Open No. 4-12625, all the systems are collectively searched for the supply validity which is a quantitative evaluation index of the supply suitability of each feeder that can be supplied to each node. A method and an apparatus for determining a flexible form have also been proposed. In this collective processing of all systems, it is important to accurately calculate the supply adequacy of each feeder for each node.

的に各々数1と数2で定義される供給密集度と供給距離
とを用いて求める。In Japanese Patent Laid-Open No. 12625/1992, the supply validity of each feeder to each node is basically determined by using the supply density and the supply distance defined by the formulas 1 and 2, respectively. Ask for.

路である。したがって、各フィーダにとって着目ノード
へのSLPが存在することは、それに供給可能であるた
めの必要条件となる。Supply density = (reserve amount of feeder) / (total load amount of node having SLP related to the feeder) (Equation 1) Supply distance = (reserve amount of feeder−total of relay nodes other than target node) Load amount / (feeder spare amount) (Equation 2) Here, the feeder spare amount is the supplyable capacity of each feeder that is not accommodating to any node. SLP (Sho
rtest Load Path) is detailed in JP-A-63-310333 and JP-A-4-12625. It is a supply path that minimizes the load on the (relay node). Therefore, for each feeder, the existence of the SLP for the target node is a necessary condition for supplying it.

はならない。On the other hand, from the node of interest, the feeder having the SLP becomes a candidate for the feeder that can be supplied to the node of interest. However, if the SLP of the feeder is branched, not all nodes on the SLP can be supplied within the range of the reserve amount, so even if the node of interest has the SLP, it can always be supplied by that feeder (necessary). Not a sufficient condition.

も80/(50+5+15+20)≒0.889 とな
る。フィーダF2については40/25=1.6。As described above, the supply density defined by the equation 1 is only a necessary condition that the existence of SLP can be supplied by the feeder. However, this only gives a rough evaluation of each feeder for the node of interest. Figure 2
In the example shown in (1), the reserve amount of the feeder F1 is 80, the SLPs are # 1 → # 2 → # 3 and # 2 → # 4, and the tip of # 2 is branched. In the figure, each circle is the node to be accommodated, the number in the circle is the load of the node, the broken line is the switch (the broken line in the arrow is the interconnection switch), and the number in () is the supply reserve amount of the adjacent feeder. Show. # 1 → # 2 part before branch and # 3, # 4
The values of the density should be distinguished from and, but both are 80 / (50 + 5 + 15 + 20) ≈0.889 in the equation 1. 40/25 = 1.6 for feeder F2.
【0008】一方、着目ノードまでの距離を数2で定義

給距離と合わせて、#2への供給妥当性はF1よりもF
2の方が高いことになる。その結果#2がF2で供給さ

電してしまう。On the other hand, although the distance to the target node is defined by the equation 2, since it is normalized by the reserve amount of each feeder, for example, for # 2 in FIG.
2 has a higher degree of closeness (F1 → # 2:
(80-50) /80=0.375, F2 → # 2: (40-
20) /40=0.5). Therefore, together with the supply density and the supply distance, the supply adequacy to # 2 is F rather than F1.
2 is higher. As a result, # 2 is supplied by F2, while # 3 can only be supplied by F1, so that power failure occurs at # 3.

単な手法が必要となる。[0009] In Japanese Patent Laid-Open No. 12625/1992, in consideration of the fact that # 3 can only be supplied in F1, it is possible to increase the validity of supplying F1 to # 2 without correction.
However, a simple method is required to raise the supply validity of F1.

ダについては配分を小さくする。In the present invention, attention is paid to the fact that it is effective in avoiding a power failure by selecting, as a supply feeder to each node, one that can supply more power to that node, and the supply capacity Uses the number of feeders that can be supplied to each node. Then, in order to perform distribution based on the demand side needs at each branch, the load amount of the node that can be supplied by the feeder belonging to each branch and the number of other alternative feeders that can be supplied are calculated. If the target becomes large-scale and the number of branches increases, it will be difficult to properly allocate the target.
Increase the distribution of appropriate feeders and decrease the distributions of other candidate feeders.

Therefore, waste associated with uncertain distribution can be reduced, and more appropriate supply adequacy can be calculated.

Basically, the difference from the method described in -12625 is that a block 103 is added and the capacity that can be supplied to a node that can be supplied to each feeder is obtained, and this information is further used to calculate the supply validity of the block 104. That is the point.
【0015】ここで図2に示す例題を用い、供給可能容

前の#4の負荷量20を差引いた残り20となる。First, with respect to the feeder F2, the nodes that can be supplied are # 2 and # 4, and since there is no branch, the available capacity is 40, which is the reserve amount of F2 for # 4, and the preceding is for # 2. The remaining 20 is obtained by subtracting the load amount 20 of # 4.

As for the available capacity, the available capacity is 80 and # 1 respectively.
It becomes 30 which deducted the load amount of. Since # 3 and # 4 fall into a branch, it is necessary to allocate 25 after passing through # 2 by some standard. Table 1 uses only the information on the load amount of the node for each branch. Here, simply, the load amount that can be supplied for each branch is distributed as the expected load amount in the ratio of the supply distance. As a result, # 3 is 25 × 15 / (1
5 + 20) ≈10.7, and # 4 is 25 × 20 / (15 + 2)

と、表1に較べ、より適切な値が求まる。On the other hand, the available capacity shown in Table 2 also considers the number of feeders that can be supplied to each node. That is, the sum of Li / Ni obtained by dividing the load amount Li at the node #i by the number Ni of feeders that can be supplied is calculated for each branch and distributed by the ratio. As a result, Li / Ni is 15/1 = 15 for # 3 and 20/2 = 10 for # 4, and the available capacity is 25 × 15 / (15 + 1) for # 3.
0) = 15, # 4 is 25 × 10 / (15 + 10) = 10
Then, a more appropriate value is obtained as compared with Table 1.

い。For the supply adequacy for each feeder of each node, the supplyable capacity shown in Table 1 or Table 2 is normalized by, for example, 80, which is the maximum feeder reserve capacity in this case, and F1 is obtained.
# 1 is 1.0, # 2 is 0.375, ..., and F2 is # 4 is 0.5, # 2 is 0.25, and so on.

Regarding 2, the supply relevance of F1 is higher and the supply of F2 is performed, so that the supply route to # 3 is secured and there is no power failure.

クの部分を、微妙なものまで含めて明確に判定するのは
一般的には困難である。This problem is caused by the fact that the supply capacity of each feeder was not properly distributed in the branch. In the above method, boundaries are raised based on the rough "power" to each node from the viewpoint of supply capacity for each feeder, so the neck part that should be supplied only by a specific feeder in order to avoid a power outage is delicate. It is generally difficult to make a clear decision, including the ones.

FIG. 5A shows a feeder having an SLP that can be supplied to each node within the range of reserve capacity. . # 1 to # 6 cannot be supplied from F2. on the other hand,
F23 cannot be supplied to # 23 and # 25, and only F1 can be supplied to # 21 and # 22. F21 to # 21 and # 22
In order to supply in # 2, # 23 and # 24 must also be supplied in F1, and eventually, # 21 to # 25 must be supplied in F1. These correspond to the condition (1).

In 5), the reserve capacity is 10 more. Therefore, F1

Must. That is, # 1 to # 7 (supplied by F3), # 11 and # 12 (supplied by F2) correspond to the condition (2). To summarize the above, it is necessary to use the power supply shown in FIG. 5 (2) to avoid power failure. The remaining # 8 to # 10 and # 13 to # 2 are fed to the feeders F1 to F3.
It is necessary to find an interchange pattern that does not cause power failure by appropriately dividing with.

And 95% of each load of # 23 to # 25 is F3.
