Design and Implementation of Distant Signal Transmission Through Optical Fiber

在纵联距离保护系统中,使用远方信号传输装置以代替高频收发信机,可以有效克服电力线复用载波通道所带来的不可靠性,从而大幅度提高信号的传输速度和通信容量,明显增强线路保护装置和安全自动装置的可靠性、准确性和及时性。利用光纤通道实现远方信号传输,是适用于智能电网的最佳传输机制。文中介绍了采用光纤传输的机理、要求及实现方法。

In pilot distant protect system,instead of using high-frequency transceiver,long-distance signal transferring device can overcome unreliability caused by power line carrier channel multiplexing.Therefore,transmission speed and capacity of line is increased quite a lot so,that significantly enhanced reliability,accuracy and timeliness of line protection and automatic safety device.Using fiber channel to achieve the distant data transfer is the best transmit technology in smart grid.In addition,the mechanism of optical fiber transmission,requirements and implementation methods is also described in this paper.
