    Abstract SSRF project mainly consists of electron linear accelerator，intensifier， electron storage ring and electric heating system，showing a total installed capacity of about 12 000 kVA. Main electric equipment for the electron linear accelerator，intensifier and electron storage ring is power supply device of dipole / quadrupole / sextupole magnet， and is mostly rectifier equipment，generating 11t h and 13t h higher harmonic.

At the beginning of design，mechanism analysis on harmonic source of the distribution system has made，the internal structure of harmonic source has improved to reduce the harmonic. In addition，the system harmonic is forecasted by means of simulation experiment，and this provides scientific basis for comprehensive treatment of harmonic of the distribution system of SSRF project at the later stage.

    摘　要　上海光源工程主要由电子直线加速器、增强器、电子储存环及电加热系统等配套设施组成，总装机容量约12 000 kVA，其中电子直线加速器、增强器、电子储存环的主要用电设备均为2极、4极、6极磁铁的电源装置，且绝大部分为整流设备，所产生的高次谐波主要是11次和13次。

上海光源工程在设计之初就考虑谐波影响，对其配电系统中的谐波源进行机理分析，改进谐波源的内部结构以减小谐波，并通过仿真实验预测系统谐波，为上海光源工程配电系统的后期谐波综合治理提供科学依据。
