| 摘 要： | 数字化变电站中采集器与合并单元之间通信遵循IEC60044—7／8标准，分析IEC60044—7／8中采用的曼彻斯特传输码与CRC校验码。分别对当前光纤通信中使用最广泛的485B码与FT3帧格式中使用的曼彻斯特码、BCH纠错码与FT3帧格式中的CRC校验码进行对比，提出使用485B码代替曼彻斯特码、BCH码代替CRC校验码的新的传输方案，并对新方案进行仿真从而证明新方案的优越性。

| Abstract: | The communication between Collector and Merging Unit of digital substation follows the IEC60044-7/8.Analysis the Manchester transmission code and CRC checksum used in IEC60044-7/8.Compare the 4B5B coding widely used in current optical fiber with the Manchester coding used in FT3 agreement and the BCH error-correcting code with the CRC check code used in FT3 agreement,then come up with a scheme that using 4B5B coding instead of Manchester coding,BCH coding instead of CRC coding.The result of the simulation proves that this new plan is better. |
