面向电力隔离装置的高可靠跨区传输方法研究

Research on High Reliability Transmission Method Across Security Zone for Power Isolation Devices

云计算等新技术在电力企业的大规模应用使传统电力安全分区模式难以有效支撑现有业务,文章基于TCP提出了一种简化的跨安全区交互协议,屏蔽了设备底层的文件传输细节,统一生产控制大区与管理信息大区之间交互接口,满足请求/应答、订阅/发布传输模式。利用多线程技术开展面向电力隔离装置的多通道数据传输,建立了跨区优先级控制与数据确认机制,实现了高可靠的跨安全区传输,最后给出实验验证过程及结果,有助于提升电力安全分区之间的信息共享能力。

The large-scale application of new technologies such as cloud computing in power supply companies makes the mode of traditional power security zones cannot efficiently support the existing businesses.A simplified interaction protocol of crossing security zones is proposed based on the TCP,which encapsulates the file transfer protocol in the base of isolation devices.It unifies the exchange interface between the production&control zone and the management&information zone,and the transmission modes of request/reply and subscription/publication.Multi-channel data transmission in isolation devices is implemented by multi-thread technology.It established data confirmation mechanism by priority controlling in crossing security zones.It implemented high reliability of transmission of crossing security zones.Finally,it gives experiment process and results.The method helps to improve the ability of data sharing across different power security zones.
