电力实时数字仿真(RTDS)系统是分析电力系统特征、测试继电保护及二次设备的重要手段,得到了广泛应用.采用电子式互感器后,RTDS系统不再需要D/A转换和功率放大等环节,可以直接将仿真产生的数据经格式转换后加以使用.文中研究了基于IEC 61850标准的新型RTDS系统的构成和实现,介绍了连接RTDS系统与全数字二次设备的测试模型,通过对110 kV线路数字化保护的试验验证了系统的实用性.

The widely used electrical real-time digital simulation (RTDS) system plays an important role in the stability analysis, security assessment, relay protection equipment test, etc. With the adoption of electronic transformers, neither D/Aconversion nor power amplification is needed in the RTDS system. The data output by simulation software can be directly used through format conversion. The structure and implementation of a new RTDS system based on IEC 61850 standard are discussed. The test model connecting the RTDS system and digital secondary devices is described. The practicality of the proposed RTDS system is validated by a 110 kV line all-digital relay protection module.
