提出了基于嵌入式PLC软核的通用配网保护平台设计方案。针对传统保护软件编程灵活性差，现场可配置能力弱的问题，在分析嵌入式PLC软核的特性并讨论了基于PLC软核技术实现110 kV及以下配网综合保护的可行性和优势的基础上，实现了基于嵌入式PLC软核的通用保护平台。设计了基于PLC软核的保护平台系统结构，然后在以ARM9200芯片为核心的硬件平台上实现了PLC软核的移植和调试。采用模块化设计思路，通过结构化文本语言（Structure Text）实现了差动保护、零序电压保护、反时限电流保护等面向配网主设备的保护功能。最后，以10 kV电动机为被保护对象，从保护特性和电磁兼容性等方面进行测试。实验分析表明，所实现的保护平台具有配置灵活，通用性好的优点，各保护参数满足GB/T 7261-2008和GB/T 14598国标要求。

This paper proposes a universal protection platform based on embedded soft core PLC. Traditional software programming has poor flexibility and weak field configurability. After analyzing the characteristics and advantage of embedded PLC soft core, we implement a universal protection platform based on embedded PLC soft core. We design the system structure of protection platform based on PLC soft core, then transplant and debug the PLC soft core on ARM9200 based hardware platform. We realize the widely used distribution grid protections, such as the differential protection, zero sequence protection, inverse time current protection by Structured Text Language, using modular design concept. At last, we take a 10 kV motor as protect object. Experimental analysis shows that the protection platform has good flexibility and versatility. The protection parameter meets GB/T 7261 2008 and GB/T 14598 GB requirements.
