摘　　要：针对数字化变电站的一次设备、二次设备的变化,从信息采集方式、控制方式、通信方式等方面说明了数字化变电站安全稳定控制技术与传统变电站的不同,并根据数字化变电站的特点和要求,详细介绍了基于IEC 61850的安全稳定控制装置系统的构架、硬件平台和软件结构,并对稳定控制装置采用的基于现场可编程门阵列(FPGA)的高实时性电气量算法进行了描述。试验结果证明:这种电气量算法的实时性和精度高于传统方法,特别在频率偏离工频时基波有效值计算有明显的精度优势,能够满足数字化变电站安全稳定控制的要求。Based on the characteristics of digital substation equipments, the security and stability control technology implemented in digital substations is compared with that implemented in conventional substations in aspects such as information acquisition method, control mode and means of communication. A security and stability control device based on the IEC 61850 standard is developed according to the requirements of digital substations. The system architecture, hardware platform and software structure of the device are introduced. The field programmable gate array （FPGA） based algorithm for computing electric quantities in real-time is described. Experimental results show that the real-time performance and computation accuracy are superior to those of conventional methods. The advantage of computation accuracy is more evident under the condition when the system frequency deviates from the fundamental frequency of 50 Hz.
