数字化变电站集成保护信息共享通信特性分析研究

Digitized Substation Integrated Protection Information Sharing Communication Characteristics Analysis Research

数字化变电站中继电保护的数据通信与保护跳闸等环节的实现形式已经发生了重大变革,其技术条件也促进了集成保护的发展。目前,对35 kV及35 kV以下变电站,保护测控相互融合、信息共享,保护、测控功能集成在一个独立的装置中,已经成为业界共识。而实时、可靠的网络通信是数字化变电站实现集成保护的先决条件和关键技术。因此,以35 kV数字化变电站为例,利用主流通信仿真软件—OPNET对其信息共享特性进行仿真研究。

Realization of relay protection in digital substation data communication and protection trip link has been changed, the technology also promotes the development of integrated protection. At present, the substation on 35kV and 35kV,protection and control integration, information sharing,the functions of protection,measurement and control integrated in an independent device, has become the industry consensus. The network communication of real time, reliability is the condition and key technology of digital substation, the prerequisite to realize the integration of protection, therefore, based on the 35kV digital substation as an example,the use of mainstream communication simulation software-OPNET to the sharing of information to do simulation research.
