变电站综合自动化是一项提高变电站安全、可靠稳定运行水平,降低运行维护成本,提高经济效益,向用户提供高质量电能服务的一项措施。随着自动化技术、通信技术、计算机和网络技术等高科技的飞速发展,一方面综合自动化系统取代或更新传统的变电站二次系统,已经成为必然趋势。另一方面,保护本身也需要自检查、故障录波、事 Integrated substation automation is a measure to improve substation safety, reliable and stable operation, reduce operation and maintenance costs, increase economic efficiency, and provide users with high quality electrical service. With the rapid development of high technology such as automation technology, communication technology, computer and network technology, on one hand, it has become an inevitable trend to replace or update the traditional secondary substation system with integrated automation system. On the other hand, the protection itself also needs self-inspection, fault recording, things
