Abstract

The invention provides an SOC-based electric power direct current system fault recording and broadcasting method. The method comprises the steps that all paths of alternating current and direct current analog quantity signals are accessed from an electric power direct current system, are collected, filtered and isolated by a signal conditioning circuit and then are sent to an AD sampling circuit,multiple paths of parallel SOC core algorithms are used for obtaining, caching and packaging collected data into a standard UDP data packet, and the standard UDP data packet is sent to a network storage server from a network interface. The method has the remarkable characteristics of full-hardware parallel data processing, high data acquisition speed, high reliability, good real-time performance and no performance bottleneck.

Description

technical field [0001] The invention relates to the field of electric DC system monitoring, in particular to a SOC-based method for recording and broadcasting faults in the electric DC system. Background technique [0002] The DC power supply system of the substation is an important part of the power system. It provides DC power for the signal equipment, relay protection, automatic device, emergency lighting, circuit breaker and closing operation of the substation, and guarantees the power supply in the event of an external AC fault. The backup power supply continues to provide important equipment for DC power supply, and is the basic guarantee for the normal operation of equipment such as relay protection, automatic devices, and circuit breakers. Its stable operation is essential to prevent system damage, accident expansion, and serious damage to equipment. [0003] In recent years, there has been an upward trend in the accidents of protective device misoperation and refusa...
