摘　　要：针对常规变电站自动化系统保护功能不足问题,利用间隔层智能电子设备通过数字通信网络进行信息交互,协同实现保护功能。其实现方法是对现有的智能一次设备,提出满足IEC61850规约的基本二次功能,再通过对智能一次设备的研究和功能扩展,为网络化保护发展提供条件。最终实现了满足现有变电站自动化系统安全性、可靠性、稳定性且遵循IEC61850规约的网络化保护,体现了变电站二次系统应用功能的创新。该产品已经在数字化变电站工程中投入运行,并取得了良好效果。Aiming at the defect of normal substation automatic system protection, the interval intelligent electronic device is used to realize both the information communication via digital communication network and the protection function. The realization method creates a condition for networked protection mainly through proposing a basic secondary function which meets the needs of IEC61850 protocol on the basis of existing intelligent primary device and then analyzing and expanding the function of intelligent primary device. The networked protection which possesses security, reliability, stability of existing substation automatic system and complies with IEC 61580 is realized eventually, which reflects the innovation of application function of substation secondary system. The products have been put into practice in digital substation projects, and the application effect is good.
