| 摘 要： | 从中压配电线载波通信DL 790系列标准出发,尤其针对DL/T 790.31标准,现场测试中压架空配电线载波通信的频谱干扰,结果分析显示,按照DL/T 790.31标准,中压配电线数字载波通信装置设计为标称信号输出功率最大5 W(37 dBm),其所产生的泄漏干扰不会对现有的载波通信系统,尤其是继电保护专用电力线载波收发信机系统产生干扰。 |
| 关 键 词： | 中压配电线 载波通信 频谱干扰 DL790系列标准 |

| Abstract: | According to DL/T 790 series standards,especially DL/T 790.31 standard,the measurement of spectrum disturbance of carrier communication over Medium-Voltage(MV) overhead distribution line has been carried out.The results indicate that the spectrum leak of the MV carrier communication device does not interfere with the existed carrier communication system,especially carrier transceiver for relay protection under the 5 W(max) nominal signal output power. |
| Keywords: | Medium-Voltage(MV) distribution lines carrier communications spectrum disturbance DL 790 series standards |
