The flexible grid interface equipment for distributed photovoltaic power generation integrates most of the functions of distributed photovoltaic power generation equipment,such as the relay protection,measurement and control,electric power quality control,telecontrol and harmonic elimination,etc. It is used to connect the distributed photovoltaic power generation system to the power grid and realizes the centralized management to distributed photovoltaic power generation. In addition,it is also an important technical means to realize the 'plug and play'function of distributed photovoltaic power generation. This paper introduced the specific research contents of flexible grid interface equipment,proposed a control mode of'main control box + distributional control modules ',solved the large harmonic wave problem of distributed power generation unit when it is running under low power condition,and realized the anti-islanding function at the interface.
