PURPOSE:To reduce setting labor and error of input data, by obtaining load quantity through predetermined operation for a load for which load quantity can not be obtained based on a typical supply/demand data, then setting the load quantity automatically as input data. CONSTITUTION:Power is fed from a power station 1 through a transmission line 2 to loads 3a-3d. In power interchange calculation, information of respective switchgears in power system is first collected and load measured for respective loads are collected. Measured load quantity flowing from the power station 1 to the transmission line 2 is P and typical supply/demand data to be fed to the loads 3a-3d are Ya-Yd. If quantity of load 3a, can not be obtained, its load quantity Pa is calculated through the formula, and set automatically as data for calculating power flow. |
