<P>PROBLEM TO BE SOLVED: To facilitate high accuracy simulation, and facilitate simulation of various types of loads with different computation cycles. <P>SOLUTION: This three-phase AC load simulation device constitutes an analog circuit which is electrically similar to three-phase AC load of a power system, applies voltage to the analogue circuit from a simulator system to cause a current to flow, and to simulate a system phenomena generated in the power system. A load simulation device 20' is constituted of a digital computation device 21' provided with a plurality of computation processing portions, a voltage-detecting device 23 which detects the voltage applied from the simulator system, a current source 24 which flows the load current corresponding to a current command value from the digital computation device 21', and a breaker 25. The function of the three-phase AC load to be simulated is realized in a control block diagram, constituted by combining a plurality of control parts 216 by the digital computation device 21', and a load computation program of the digital computation device 21' is generated, based on this control block diagram. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
