On the basis of the computed value, a receiving power target value interpolation means 3 computes an interpolated power receiving point power target value so that a target value of each section during the setting period, if a change direction of the target value from the preceding section for the own section and a change direction of the target value to the subsequent section are identical, will vary in magnitude in the own section and a time integral value in the own section will have a same value as a time integral value in a section for the same target value.

SOLUTION: A CPU of a multifunctional protection relay device determines the connection state of the secondary side of the transformer and the input terminal of the multifunctional protection relay connected to an A/D conversion circuit from the relation between a current Ir detected by a current transformer via the A/D conversion circuit, the phase of Ir, and an R-S interphase voltage similarly detected via the transformer and A/D conversion circuit, the phase of T-S interphase voltage. When any of them is in reverse phase connection, an instantaneous electric power W is calculated by reversing the polarity of the interphase voltage which is detected in the reverse phase connection.
