摘要:
In an agent system having a plurality of agents each of which executes predetermined processing while moving through a plurality of nodes connected to an information network, the plurality of nodes respectively have a plurality of agent platforms which receive and execute the agents, one of the agent platform and the node has synchronization means, and when the plurality of agents which are running on the same node should synchronously execute operation, the plurality of agents on the same node execute processing synchronously by sending a synchronization request message to the synchronization means.

The present invention relates to a system for protecting and controlling main-circuit components of an electricity transmission substation. The system includes devices for digital data output, protection-and-controlling, component controlling-and-monitoring, and communication. The digital data output devices input analogue AC electric values and output digital data. The protection-and-controlling devices input the data from the digital data output devices, and further control, monitor, and protect the substation main-circuit components. The component controlling-and-monitoring devices receive commands from the protection-and-controlling devices or from the substation controlling-and-monitoring equipment, and further control and monitor the substation main-circuit components. The devices for digital data output, the protection-and-controlling, and component controlling-and-monitoring are disposed near or within their corresponding substation main-circuit components.
摘要:
In a data management unit in a computer system, the computer system has a computer in which the data management unit is incorporated, and a terminal intercommunicates with the computer. In the data management unit, an object data storage unit (memory) stores in addresses thereon data items to which the terminal is adapted to make access. A parameter management file stores thereon parameters concerning a data structure of each data item. The parameters include a data name of each data item, a data type of each data item, an address related to each data item on the data storage unit and an array information of at least one data item. Then at least one data item has an array structure, and the array information includes a number of the array elements. On a number of bytes definition table, a number of bytes corresponding to each data type of each data item is stored. A data table producing module is adapted to make, according to the parameters concerning the data structures of the data items of the numbers of bytes of the data types, an address related to each data item in array element units on the memory (data storage unit) correspond to each data name of each data item so as to produce a data table.
摘要:
In the electric power system protective control system, a plurality of protective control apparatuses each having a protective control function to an electric power system are distributed and connected through a communication network to each other so that data communication is permitted among the respective protective control apparatuses. Each of the protective control apparatuses is carried out a process of executing a control operation related to the protective control function of the own apparatus according to a program module. The program module migrates through the communication network to the own apparatus along a predetermined route of migration. Each of the protective control apparatuses executes a process of migrating the program module from the own apparatus to another protective control apparatus. The another protective control apparatus is determined to a next destination of migration according to the route of migration. In a case where the program module is not migrated by the migration process to the next destination protective control apparatus, each of the protective control apparatuses executes a process of changing a next destination of migration of the program module to a predetermined protective control apparatus except for the next destination protective control apparatus, making it possible to prevent the program module from stopping.
