摘要
由于家用电器的数量及种类大量增加,住宅小区电力谐波污染日益严重,对小区内部安全、可靠供电产生了严重威胁,因此分析谐波的危害以及相应治理预防,对改善小区供电质量和确保电力系统安全可靠运行有着重要的实际意义。本文主要以典型小区作为案例,分析目前小区供电的谐波污染状况,并通过增加有源滤波器,对比分析出有源滤波器对小区供电的谐波治理效果。从有源滤波器的治理案例上可以看出,有源滤波器可以针对不同次数的谐波同时补偿,补偿效果非常明显。
With significant increase of home appliances both in quantity and variety, the power har- monic contamination at residential area becomes more and more serious, causing a serious threat to the security and reliable power supply. Therefore, it will be of great importance in improving power supply quality of the residential area and assuring safe and reliable operation of power system. In this paper, takes the typical residential area as an example, analyzes the harmonic contamination of ample of active power filter that the filter can simultaneously compensate for the different orders of harmonics, and have significant compensation result.
