Abstract
This invention provides a protection control measurement system, with excellent economy and maintainability. In the protection control measurement terminal, electric quantity acquisition and transmitter-determines synchro-phasor quantities from electric quantity data and transmits the synchro-phasor quantities to arrival time-guaranteed transmitter-. The arrival time-guaranteed transmitter-transmits in real- time the synchro-phasor quantities to the parent station device. Setting value transmitter-transmits setting value data to the message transmitter-, which performs message transmission to the parent station deviceover the communication network. In the parent station device, electric quantity arithmetic processor-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-performs arithmetic operations for accident judgment for protection control measurement terminalsfrom the magnitudes of electric quantities and voltage phase differences.
