摘要:
继电保护装置是电网安全运行的关键设备,其关键部件自主化程度不高,亟需自主化改造。继电保护装置自主化面临的主要问题是主控芯片选型困难及存储芯片可靠性、一致性不高等问题。从芯片自主化标准的研究出发,遵循继电保护装置可靠性、选择性、灵敏性和速动性的基本要求,详细描述了基于龙芯处理器的继电保护装置平台框架,主要包括主控芯片选型标准、整体平台架构、双核运行模式、核间数据交换、存储检错纠错等方面的内容,从硬件和软件两方面介绍自主可控继电保护装置平台的设计原理和关键技术。基于设计平台方案的继电保护装置已经在多座变电站挂网试运行,运行情况良好。

Abstract:
Relay protection devices are the key equipments for safe operation of the power grid, but the auto-nomization degree of their key components is not high, so the autonomization reconstruction of them is urgent. The main problems of the autonomization of relay protection devices are the difficulties in selecting the main control chip and the low reliability and consistency of the memory chip. Starting from the research of chip autonomization standard, following the basic requirements of reliability, selectivity, sensitivity and rapi-dity of relay protection device, the platform frame of relay protection device based on Loongson processor is described in detail, mainly including the main control chip selection standard, the overall platform structure, dual-core operation mode, data exchange between cores, memory error detection and correction, etc.,the design principle and key technology of the platform for autonomous controllable relay protection device are introduced from both hardware and software aspects. The relay protection device based on the designed platform scheme has been put into trial operation in many substations, and the operation is good.
Key words:  autonomization  autonomous controllability  relay protection device platform  relay protection device  relay protection  reliability
