The work of this paper has great significance to solve the technology problem of photovoltaic scale access in our country

to master all kinds of power electronic interface of new energy power generation device detection technology

and to promote new energy power generation device design level. According to the actual demand for high altitude photovoltaic power station

this paper proposes a power system simulator as a disturbance and a high voltage source

and to achieve frequency interference and disturbance of high voltage

and other functions

can satisfy the 35 kV and 10 kV voltage class testing requirements. Meanwhile

the designed high altitude grid adaptive mobile inspection system up to 4 000 m high altitude of large and medium-sized mobile test of photovoltaic power station can meet capacity of 1.5 MW and the requirements of the photovoltaic power station unit;it also can simulate the voltage and frequency of the power grid when the steady state disturbance and can detect photovoltaic power station’s ability to adapt to the disturbance. The system is used in Qinghai 200 MW photovoltaic power station of the Yellow River water and tested on site during grid fault. It shows that the mobile detection platform has practical application value.
