摘　　要：随着能源和环境问题日益加剧,作为传统电网延伸和补充的户用风光互补发电系统拥有光明的发展前景,对其电能质量问题进行研究成为必然。为了解决户用风光互补发电系统带来的电能质量问题,对该系统电能质量扰动产生的机理进行分析,并在Matlab/Simulink平台对理论分析进行仿真。仿真结果表明:谐波和闪变是系统主要电能质量扰动因素,最大功率跟踪控制、风速和光照等自然环境的改变、LC滤波器参数设置和非线性负载都会对系统电能质量产生影响。研究成果可为户用风光互补发电系统电能质量的提高及更广阔的应用提供支持。With the energy and environmental problems, as extension of traditional grid, household scenery complementary system has a very bright prospect. To study the power quality problems of this kind of system become inevitable. In order to solve the household scenery complementary power quality problems brought by power generation system, in this paper, the mechanism of power quality disturbance is analyzed, and the theoretical analysis is simulated on Matlab/Simulink platform. As a result, specify harmonic and flicker is the main power quality and disturbances. Simulation results showed that the maximum power tracking control, the natural environment such as wind speed and illumination changes, LC filter parameter and nonlinear load had large degrees of influence on the system power quality. This paper provides support for power quality improving and wider application for household scenery complementary system.
