摘要： PURPOSE:To judge a faulty facility with high speed and high reliability, by combining power interruption facility groups adjoining through trips CD and forming power interruption facility groups, then judging a faulty facility for every group. CONSTITUTION:System information prior to occurrence of system fault, system information immediately after occurrence of fault and trip information of circuit breaker are taken in, then rower interruption systems having electrical relation are classified to form power interruption facility groups R1-R6. Power interruption groups R1, R3 and R5, R6 adjoining through a trip CB are classified into one power interruption facility group, while remaining groups R2, R4 are classified into another group. Operational information for main and standby protection relays is edited for every group so as to judge faulty facility for every group.

摘要： PURPOSE:To rapidly select a stop decision notice information notifying designation by automatically selecting an enterprise in which a switch opening or closing operation is executed to stop a facility to be stopped on the basis of data of the facility to be stopped of a power system which was input in advance and connecting relation data of the power system. CONSTITUTION:Data of facility to be stopped of a power system is input by an automatic selector 4, and an electric facility connected to the facility to be stopped is selected as a notifying destination from the connecting state data of a power system stored in a first memory 5 on the basis of the data of the input facility to be stopped. Then, an enterprise relating in the operation of the power system is selected as a notifying destination on the basis of operation organization data of the power system stored in a second memory 6 from the selected electric facility. Accordingly, when the facility of the power system is stopped, a stop decision notice information notifying designation can be accurately and rapidly selected from the facilities to be stopped.

摘要： PURPOSE:To form an accurate system operation sequence in which a power interruption range becomes necessary minimum by discriminating a power interrupted facility of a system state that a facility to be stopped is disconnected on the basis of a system state of an operating day, and detecting a relating power interruption facility and a slave power interruption facility. CONSTITUTION:A facility to be stopped is disconnected from a system state of an operating day in a simulation manner on the basis of data, such as information relating to facility group for forming a power system and basic construction data of the power system made of coupling information representing the connecting relation of the group, and the discrimination of the power interrupted facility in the disconnected power system is conducted by a computer 3. Then, a relating power interruption facility and a slave power interruption facility which are stopped due to the stop of the facility to be stopped are detected, and the system operation sequence is formed of a system operation instructing sequence forming unit 6 to use or switch the facility which can avoid a power interruption.

摘要： PURPOSE:To correctly discriminate a power interruption even if a malfunction occurs at part of voltage detectors by dividing facilities in a system into electrically connected groups, and discriminating a power interruption by a decision by majority with voltage state information in each group. CONSTITUTION:Various state information of power system facility is input to input processing means 11, and stored in memory means 12. The facilities in the power system is sorted into facility groups each having an electric connection by facility group discriminating means 13 on the basis of memory information. Whether each facility is power-interrupted or non-power-interrupted is discriminated by using the voltage state information of a voltage detector by voltage state discriminating means 14 at each facility group. The discriminated information is compared by power interruption facility discriminating means 15, and when the number of the facilities exhibiting a power interruption state is equal to or more than that of the facilities exhibiting non-power interruption state, the whole facility group belonging to the facility is discriminated as a power interruption.

摘要： PURPOSE:To rapidly and correctly grasp field information by grouping respective pieces of the field information, successively storing them into a memory, making the group of the memory area into the updated group in a time series unit, and renewing successively from the older group of other groups. CONSTITUTION:A file A for the constant number of affairs is divided into plural groups at the output unit of information and to respective groups 1-m, a time series sequence 1-i of an information output is specified. When the memory area of the file A is not full, respective pieces of the field information are stored into respective memory areas of the groups 1-m in accordance with the time series sequence fetched into a computer 24, respectively. On the other hand, for the generation of the new field information, when the memory area of the memory is full, all pieces of the field information of an oldest group (m) of the file A are abolished and the time series sequence of the group is made into the newest group. Thus, the speed up of field information storing processing and displaying data editing can be attained.

摘要： PURPOSE:To transmit data from slave stations placed in the master station side of the faulty point even if the fault occurs in a certain slave station, by connecting a light emitting diode for receiving and a transistor for returning, which are connected to a constant voltage or constant current circuit, in directions opposite to each other to constitute a transmitting and receiving circuit of the slave station. CONSTITUTION:In case of data transmission from a master station 1 to a slave station 2 or 3, a transistor 12 is turned on and off through a photocoupler 11 to transmit data to a photocoupler 21 connected to a constant voltage circuit (or a constant current circuit) 22 in the slave station 2 or 3. Meanwhile, in case of data return from the slave station 2 or 3 to the master station 1, a photocoupler 111 in the master station 1 is turned on, and a photocoupler 15 is turned on. Under this state, a photocoupler 27 in the slave station 2 or 3 is turned on and off in accordance with return data to transfer this return data to a photocoupler 16 in the master station 1. Consequently, even if a fault occurs in the slave station 3, data transmission between the slave station 2 and the master station 1 is not troubled by the action of the constant voltage circuit 22.

摘要： PURPOSE:To keep the continuity of a synthesized map by recognizing the longitude and latitude on a map by a computer and correcting generated errors automatically by another computer. CONSTITUTION:Topographical maps G, H including longitude and latitude are inputted to a computer 2 through an image input device 1. The inputted image data are sent to a computer 6 and horizontally continued dot data on the maps G, H are converted into run length vector data (d). The longitudes c, b on the maps G, H are recognized by the computer 6. A reading error generated at the input of the image is corrected to a previously fixed interval by correcting its distance interval through the computer 2. At that time, the run length vector data (d) is also corrected by the same correction factor. The previously recognized longitude is matched at the connection part (a) of a map I to form the intersected point (e) of the recognized segments.
