一种新的智能变电站通信业务安全隔离技术的研究

为了保障智能变电站通信网络的可靠性和安全性,必须对网络中的通信业务流进行安全隔离传输。分析了智能变电站通信业务流的特点,简述了目前常用的网络隔离技术,着重剖析了目前智能变电站通信网络采用的业务隔离技术的应用情况和特点,指出智能变电站通信业务流对安全隔离的迫切需求。研究了全光交换技术的分类和主流技术的主要特性指标,探索性地提出基于全光波长和全光标签混合交换技术的电力业务安全隔离方案,并详细介绍了方案的技术原理和实现措施。通过引入业务隔离评估模型,以实验方式论证了该方案的可行性。

A new method of smart substation communication service security isolation technology

In order to guarantee the reliability and security of the communication network of smart substation, it must carry out the safety isolation transmission of communication business network flow. This paper analyzes the features of smart substation communication business flow, expounds the present commonly used network isolation technology, emphatically analyzes the application and characteristics of business separation technology of smart substation communication network, and points out urgent demand of communication service flow for the safe isolation. The main characteristic index and the classification of the mainstream technology of all optical switching technology are studied, the power business safety isolation scheme based on all-optical wavelength and optical label mixed switching technology is explored, and the implementation of measures and the technical principle of the program are introduced in detail. Through the introduction of business segregation evaluation model, the feasibility of the scheme is proved by way of experiment.
