Once the unattendedsubstation became a reality, the substation could be made smaller, located nearer the load, and long feeders were no longer necessary.
一旦无人值班变电站得以实现，变电站就可以造得更小，更靠近负荷，也不再需要长的馈电线路了。

Optical fiber technology is widely used by the integrated automation information transmission channel of the unattendedsubstation, so the channel reliability is very important.
无人值班变电站的综合自动化信息传输通道通常采用光纤通信通道传输，保证通道可靠传输至关重要。

As a result, it ensures the power supply reliability of unattendedsubstation technically, meets the requirement of safe power supply management and achieves the goal of maximum reformation benefits.
