Title:
ELECTRIC POWER SYSTEM SIMULATION EQUIPMENT
Document Type and Number:
Japanese Patent JP3892163
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To eliminate higher harmonic components, undesirable for simulator control, which are contained in a command signal turned into an analog signal after digital processing.
SOLUTION: This simulation equipment is provided with an analog control means 4 which simulates an electric power system, and a digital control means 1 which receives a feedback signal from the analog control means, executes specified digital processing, and outputs an analog command signal to the analog control means, and simulates system phenomena of the electric power system. An signal correction means 2 is installed which samples a command signal outputted from the digital control means by using a period shorter than the processing period of the digital control means, adds a specified number of sampling signals out of the sampled signal which are time-continuously outputted, and outputs the added signal to the analog control means, instead of the command signal.
