Design on Embedded System in Parameter Measurement for Electric Power System
Abstract
In order to avoid out of whack in large-scale complex power system caused by the influence of artificial or natural factors, this paper explores the application of embedded system in electric power system measurement of electrical parameters. In the paper, it researches the related algorithm of the characteristic parameters in power system, takes the microcomputer line protection system of a 110 kV substation as an example, constructs the software and hardware platform of electric power parameter state monitoring system based on embedded microprocessor, and designs the hardware circuit and software control program. The system commissioning results demonstrates that the designed system can determine whether the fault of the related equipment, sends correctly the trip command to make the isolation between the fault equipment and the power system so as to protect the system from being damaged. The experiment results show that it is effective and available to electrical parameter test of the embedded system based on integrated testing method in the power system for guaranteeing the safe and stable operation of power system.
