摘要： This invention provides a protection control measurement system, with excellent economy and maintainability. In the protection control measurement terminal 1, electric quantity acquisition and transmitter 14-1 determines synchro-phasor quantities from electric quantity data and transmits the synchro-phasor quantities to arrival time-guaranteed transmitter 15-1. The arrival time-guaranteed transmitter 15-1 transmits in real- time the synchro-phasor quantities to the parent station device 3. Setting value transmitter 14-2 transmits setting value data to the message transmitter 15-2, which performs message transmission to the parent station device 3 over the communication network 2. In the parent station device 3, electric quantity arithmetic processor 32-1 calculates electric quantities as close as possible to true values by multiplying received synchro-phasor quantities by setting value data. The protection control measurement arithmetic processor 32-2 performs arithmetic operations for accident judgment for protection control measurement terminals 1 from the magnitudes of electric quantities and voltage phase differences.

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.
