  现阶段我国的智能变电站通讯技术还处于发展阶段，通讯技术的配套设备应用还处于实践阶段，设备的性能与设计预想存在一定的差距，设备的稳定性相对较差，设备与二次系统的配合度低。通讯网络模式采用开放式协议，使得网络的安全性难以得到保证，加之网络节点与装置交互时，极易受到恶意攻击，使得通讯系统的稳定性差，还需要进一步研究。

    1、智能变电站通讯技术

    1.1 OTN技术

    OTN技术属于下一代骨干传送网，是在波分技术基础上拓展，应用于光层网络的传送网。OTN作为新一代光传递体系，其组网能力较强，具有较强的业务调度能力。善于解决IP业务，包括超长距离传输问题及超大宽带传输问题等，可以为2.5Gbit/s，以及10Gbit/s业务提供数据传统通道。OTN技术的应用主要发挥的是完全向后兼容的优势，除具备SONET/SDH管理功能外，还能够为WDM提供组网服务，实现端到端的连接，能够规范ROADM。

    1.2 PTN技术

    PTN技术的应用，能够完成层面设置。基于统计复用传送的要求来设计，承载多项业务。PTN技术能够支持分组交换业务的实现，且可以实现通道之间的双向点对点连接，PTN技术能够实现50s切换保护。PTN技术融合了SDH技术的优点，使得OAM更加完善，进而使得智能变电站的通讯网络不仅能够实现切换保护功能，还能够实现通道监控功能。PTN技术与GMPLS结合，实现了资源自动化配置，进而提高了网络系统的生存性能。

    2、智能变电站通讯系统组网形式

    2.1 PTP+E1组网形式

    PTP指的是精密时钟协议。PTP即时间同步技术，采用高精度时钟传输实现同步。主要是利用PTP时间，完成同步网的构建，该种组网方式具有可行性。PTP+E1组网方式，将时钟设备所发送的PTP同步信息，传输到交换机系统内部，以此确保交换机能够支持PTP，进而提供PTP信号，将数据同步信号输入到协议转换器。PTP+E1组网方式能够对以太网PTP时间同步信号进行转换，将其转换成2M数字信号，再利用SDH通信链路进行传输，各变电站的SDH设备能够接收到信息。利用协议转换器进行信号转换，对2M数字信号进行转换，使其成为以太网信号，再将以太网信号传输给变电站PTP从钟设备，利用扩展形式进行信号传输，最终实现时间同步。

    2.2 B码+E1组网形式

    该种组网形式采取是手工补偿机制，来消除传输过程中出现的延时问题，或者通过自动补偿机制，来消除信号传输时出现的延时。B码+E1组网理论精度能够达到微秒级。其主要针对时间同步设备所传输出来的信息数据，进行同步处理，在2M通道内实现封装处理，接着利用SDH网络，借助其E1通道，实现时间编码信号的实时传输，进而将时间编码信号传递到同步节点网络中。

    3、智能变电站发展方向

    智能变电站的主要建设方向是智能电网，在此过程中智能变电站是主要环节，只有提高智能变电站的智能化与信息化水平，才能尽快实现智能电网建设。基于智能电网建设体系，要将智能变电站的通信系统建设作为主要内容，构建具有较强稳定性的通信系统，实现全网通信。在构建智能变电站的过程中，要基于变电站系统功能，优化通信系统与其他系统之间的兼容，实现通信系统集成化与模块化建设，提高信息自动化采集程度，实现信息资源共享。加强智能变电站站控层的建设，站控层不仅负责控制设备与协同设备，还负责监视通信与控制通信等。因此，要基于功能需求，扩展站控层，采用紧凑架构，优化通信数据采集与传输，实现设备间的信息交互，提高智能变电站通信系统的安全性与稳定性。

    智能变电站未来的发展方向是智能电网，而智能电网的建设工作中，智能变电站建设是主要内容。智能电网系统的建设，利用通信网络与技术，
