Abstract

PURPOSE:To obtain a device for forming safe and reliable recovery plan corresponding to system condition, by judging a possibly faulty facility upon occurrence of fault then forming a recovery plan sequentially in the order of less possible faulty facility. CONSTITUTION:Information of a power system 1 is taken into an input device 2 so as to judge a power interruption zone through a power interruption zone judging means 5 based on operational information of relay or circuit breaker. A possibly faulty facility is judged through a faulty facility judging means 7 based on same information and the possibility of fault is calculated. Threshold of operational condition of the power system 1 obtained based on the system information is stored in a storage device 9. An arithmetic unit 10 prepares a recovery plan at first without employing the possibly faulty facility at all, and if the plan can not be prepared, facilities having operational condition lower than the threshold stored in the storage device 9 are employed in the order of increasing possibility so as to prepare a recovery plan.

(Prior Art) As electric power systems become more complex and enlarged, once a power outage occurs, operations for restoration become complicated and the time required for restoration becomes longer.

By the way, restoration of a load that has experienced a power outage due to an accident in the power system can be divided into two stages: determining the equipment in question and creating a restoration plan. In other words, the faulty equipment is determined based on information from relays and circuit breakers that were activated due to an accident in the power system, and then a recovery plan is created to restore the power outage without using the faulty equipment, and the system is operated. It is to do.

Conventionally, operators have determined which equipment has been involved in an accident based on information about activated relays and circuit breakers, and when it comes to creating recovery plans, recovery plans have been created in advance for hypothetical accidents. When this happens, operators make decisions based on this plan.

(Problem to be solved by the invention) Therefore, various attempts are currently being made to automate the determination of accidental equipment and the creation of recovery plans.In particular, methods using knowledge engineering and methods that apply probability are used to determine accidental equipment. If these methods are introduced, it is possible to indicate the candidates for the accident equipment using probability. In addition, there are methods for creating a recovery plan, such as a method based on a combination of recovery patterns and a method using knowledge engineering.

ところで、事故設備の判定は復旧計画作成にとって重要

By the way, determining the equipment involved in an accident is an important factor for creating a recovery plan. For example, now A and B are candidates for the accident equipment.
, 95% probability that there are three C.

4.9%、0.1%として算定された場合を考える。Let's consider the case where it is calculated as 4.9% and 0.1%.

Although it can be said from this result that A is probably the accidental equipment, there is a problem in creating a recovery plan based on this fact alone assuming that B and C are not the accidental equipment. Particularly in the case of target systems or core systems, even though the probability is low, if the equipment in question were to be used for restoration, it could cause a serious accident. Therefore, equipment that is likely to have been damaged should not be used for recovery, no matter how low the probability.

Now, when a power outage accident occurs in the power system, operating information of relays and circuit breakers corresponding to the power outage section is input to the digital computer Z via the input device 2. First, the power outage area calculating device 5 processes operation information of relays and circuit breakers to determine the power outage area and the power outage load therein, and stores the determination result in the power outage area storage device 6.

Here, a method of creating a recovery plan created by the recovery plan creation arithmetic device 10 will be explained with reference to the flowchart shown in FIG. First, the first calculation unit creates a recovery plan using only sound equipment, excluding all accident candidate equipment, and examines each of them. For example, it is examined whether all the power outage loads can be restored under the condition that the two overload frequencies do not deviate from the specified range, and if restoration is possible, that restoration plan is adopted. If the result of the analysis created and examined by the first calculation unit is that it is impossible to restore the power outage equipment, the second calculation unit predetermines the probability that the equipment is the one that has failed among the accident candidate equipment. Check for the presence of equipment that is smaller than the threshold. If there is no equipment smaller than the threshold, the creation of the recovery plan ends without being able to restore all the power outage loads. Furthermore, if there is a facility among the accident candidate facilities whose probability of being an accident is smaller than a threshold value, a recovery plan is considered using the facility with the lowest probability of being an accident facility. Then, in the same way as the above-mentioned consideration in the first calculation unit, it is examined whether all the power outage loads can be restored, and if it is possible to restore them, that restoration plan is adopted. If recovery is not possible, consider a recovery plan using equipment that is smaller than the threshold and has a lower probability of being an accident equipment,
If recovery is possible, adopt that recovery plan.

ここで、」二記しきい値については次のように決定する
ことができる。
Here, the threshold value can be determined as follows.

(1)事故が基幹系統で発生した場合にはしきい値を0
とする。すなわち、事故の可能性のある設備は復旧には
全く使用しない。
(1) If the accident occurs in the main system, set the threshold to 0.
shall be. In other words, equipment that is likely to cause an accident will not be used at all for recovery.

(2)事故が二次系統で発生した場合にはしきい値を少
し大きな値、例えば3%とする。
(2) If the accident occurs in the secondary system, set the threshold value to a slightly larger value, for example 3%.

(3)同じ区域で事故が発生した場合、重負荷時に用い
るしきい値を軽負荷時に用いるしきい値よりも小さな値
とする。これは万一事故設備を復旧に用いた場合重負荷
時の方が重大な結果を招来する可能性が高いためである
(3) If an accident occurs in the same area, the threshold value used for heavy loads is set to a smaller value than the threshold value used for light loads. This is because if the accidental equipment were to be used for restoration, there is a higher possibility that serious consequences would result if the equipment was under heavy load.
