摘　　要：电力负荷中不断增加的非线性负荷为谐波源 ,在运行中会产生谐波电压和电流。为了保证电网和电力设备的安全和经济运行 ,GB/T 1 45 4 9- 93电能质量公用电网谐波 ,规定了谐波电压和电流的限值。The growing nonlinear charge is harmonic source in electric power system. During performance it gives rise harmonic voltage and galvanism. In order to assure equipment safety and economy of its performance,the national standard GB/T 14549-93'Electric Energy Quality Communal Electric Fence Harmonic'specifies the limited value for harmonic voltage and galvanism. We can efficiently restraint harmonics with proper technical measures against harmonic source.
