按“谁干扰,谁污染,谁治理”的原则,进行谐波源当地治理。即对于产生大量谐波的用户,在用户变的低压侧加装滤波装置。根据装置的原理不同,可分为无源电力滤波器(PPF)和有源电力滤波器(APF)。随着海南省屯昌县各行各业的全面发展,屯昌县供电局的供电量不断增长。因海南特殊的地理环境,负荷分配极不均匀,季节性用电的特征充分体 Press “Who disrupts, who pollutes, who govern ” principle, carries on the local control of the harmonic source. That is, for users who generate a lot of harmonics, the filter device is installed on the low pressure side of the user. According to the principle of different devices can be divided into passive power filter (PPF) and active power filter (APF). With the all-round development of all walks of life in Tunchang County of Hainan Province, the power supply of Tunchang County Power Supply Bureau is constantly increasing. Due to the special geographical environment of Hainan, the load distribution is extremely uneven and the characteristics of seasonal electricity are fully
