详细介绍了光纤智能终端设备的硬件结构,及其在数字化变电站中的应用。该终端设备主要功能是就地完成电信号的采集,而后进行光化处理,并输出光信号,经光纤传到主控室光纤保护装置。在数字化变电站中,该智能终端与电子式互感器构成过程层,为间隔层保护设备提供最直接的电网信号。装置硬件组成包括电信号输入,电源、光化处理和光信号输出,除完成PT、CT信号的采集外,还可对多路遥信开关量进行采集。硬件平台的搭建,选用了TI公司的DSP2407作为CPU,MAX125作为高速A/D转换器,并采用HFBR1414作为电光转换输出。
The hardware structure of optical fiber intelligent terminal equipment and its application in digital substation are introduced in detail. The terminal device’s main function is to complete the electrical signal acquisition in situ, and then photochemical treatment, and output optical signals, the optical fiber transmission to the main control room optical fiber protection device. In a digital substation, the intelligent terminal and the electronic transformer form the process layer, providing the most direct grid signal for the bay level protection equipment. Hardware components include electrical signal input, power supply, photochemical processing and optical signal output, in addition to the completion of PT, CT signal acquisition, but also for multiple remote signal acquisition. Hardware platform to build, select TI’s DSP2407 as the CPU, MAX125 as a high-speed A / D converter, and the use of HFBR1414 as the electro-optical conversion output.
