如图1和图2所示，具体工作原理如下：
S01：建立通信链路。
本申请的实施例涉及到远程的主站、变电站的透明代理模块和保护装置。在变电站网关机部署透明代理模块，使用变电站网关机的调度数据网IP与主站建立TCP链接。
远程主站具备各种保护规约的接入功能。当需要接入新的变电站时，首先在远程主站按照变电站保护装置情况完成所有的配置工作，包括每个保护的网络IP地址、使用的通信规约等。
需要说明的是，主站与透明代理模块之间使用专用通信规约进行通信，专用通信规约是是为了满足主站和透明代理模块的功能需求专门定制的私有规约。透明代理模块与保护装置的规约包括标准规约或者保护厂商的私有规约。
远程主站配置完成后，如图1中S01，远程主站启动建立通信链路过程。远程主站首先与变电站网关机的透明代理模块建立TCP链接，其次建立保护装置 通信链路，具体如下：
(1)主站发送建立TCP链接信号至透明代理模块，透明代理模块接收主站的建立TCP链接信号后，建立与主站的TCP链接，之后向主站发送TCP链接建立的结果。
(2)TCP链接建立完成后，基于保护通信协议的需要，主站发送一条或多条建立保护装置通信链路命令，以建立不同端口号或者不同链路类型的通信链接。
建立保护装置通信链路命令包括保护装置的IP地址、端口号和链路类型；透明代理模块根据上述信息建立与保护装置的通信链路，并对通信链路进行通信链接编号，得到通信链路对应的通信链接编号；之后向主站发送保护装置通信链路建立的结果，其中保护装置通信链路建立的结果包括通信链路对应的通信链接编号。
S02：透传数据。
如图1中S02，远程主站与透明代理模块之间的通信链路建立之后，启动透传数据过程。
远程主站根据保护的通信协议，组织通信报文，按照专用通信规约发送规约第一数据转发命令，透明代理模块收到规约第一数据转发命令，转发其中的规约第一数据到相应的保护装置。同理，透明代理模块收到保护装置的规约第二数据后，组织规约第二数据转发命令发送到远程主站。通过透明代理模块的中转代理，可以实现远程主站与保护之间的双向通信。
需要说明的是，远程主站发送的规约第一数据转发命令包括规约第一数据和相应的保护装置的通信链接编号，透明代理模块根据规约第一数据转发命令 中的“通信链接编号”查找到对应保护的通信链路，并通过该通信链路将规约第一数据转发到对应的保护装置。
透明代理模块接收保护装置发送的规约第二数据及其通信链接编号后，组织成规约第二数据转发命令，发送到主站。其中，规约第二数据是根据保护装置的规约组织的数据，保护装置所使用规约包括标准规约或者保护厂商的私有规约。
S03：关闭通信链路。
如图1中S03，远程主站根据需要可以启动关闭通信链路过程。
当远程主站需要关闭与某个保护装置的通信时，下发关闭保护装置通信链路命令到透明代理模块，透明代理模块断开与该保护装置的通信链路，之后向主站发送关闭装置通信链路建立的结果。
需要说明的是，响应于主站与透明代理模块通信中断时，透明代理模块断开与所有的保护装置的通信链路。
通过以上实施例，可以实现如图2所示的透传效果，变电站网关机透明代理模块与远程主站有且只有一路物理链路，变电站网关机透明代理模块与每个保护建立独立物理链路。通过透明代理模块，将所有保护的物理链路报文映射到同一个透明代理模块与远程主站的物理链路，实现远程主站“直接”访问保护装置的效果，不受保护规约的限制。
在一实施例中，提供了一种基于透传链路的远程保护信息传输方法，适配置为前述实施例的透明代理模块，包括如下步骤：
根据规约第一数据转发命令，向相应的保护装置发送规约第一数据；
接收保护装置发送的规约第二数据及其通信链接编号后，向主站发送规约 第二数据转发命令；
其中，规约第一数据转发命令包括规约第一数据和相应的保护装置的通信链接编号；规约第二数据转发命令包括规约第二数据和相应的保护装置的通信链接编号。
在一实施例中，提供了一种基于透传链路的远程保护信息传输方法，适配置为前述实施例的主站，包括如下步骤：

其中，规约第一数据转发命令包括规约第一数据和相应的保护装置的通信链接编号；规约第二数据转发命令包括规约第二数据和相应的保护装置的通信链接编号。
