Abstract

A performance test system for a protective relay apparatus (100) is provided with: a circuit (3) that receives an input signal from a power grid and outputs an analog measurement value; a converter (4) that converts the analog measurement value into a digital signal; a circuit (6) that generates a test signal for the protective relay apparatus (100); a switch (2) that is provided preceding the circuit (3), and switches between the test signal and an input signal from the power grid; a CPU (5) that takes in the digital signal as input, carries out protection calculation of the protective relay apparatus (100) and issues a command to protect or control the protective relay apparatus (100) on the basis of the calculation result, and controls the switching timing of the switch (2); and a protection/monitor processing unit (5a) that compares the test signal that is inputted through the circuit (3) and the converter (4), and the test signal that is inputted directly from the circuit (6), and determines whether there is anything abnormal. The performance test system for a protective relay apparatus (100) samples test signals from the converter (4) and input signals from the power grid alternately, and monitors whether there is anything abnormal.
