| 摘要: |
| 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。 |

| Abstract: |
| 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. |
