摘要
对东莞市配电网的谐波问题进行了全面的普查,对东莞市8个镇,131个企业,247个配变,采用了便携式电能质量分析仪和在线长期监测相结合的方式,进行了实地监测。对监测数据进行统计分析后,得出了东莞配电网的谐波污染现状。结果表明,东莞配电网的谐波污染严重,超过33%的监测点的谐波电流含量超过10%,急需进行谐波治理。
A harmonics survey in Dongguan gird in the Guangdong province of China is presented. It measured 131 enterprises, 247 distribution transformers at 8 towns and 2 districts by using portable power quality analyzer with the combination of on-line measuring. Important conclusions are made and it is showed that the harmonics pollution in district grid is severe. It can be seen from that 33 percent of monitoring point＇s harmonic current distortion content rate are higher 10 percent and the harmonic pollution elimination in Dongguan must be carried out.
