Abstract

Automatic reactive power voltage control is an important means for assuring safe and stable oper-ation of photovoltaic power station. In this paper

the reactive power voltage control strategy for large scalegrid-connected photovoltaic power station is analyzed

and the test method is given in accordance with re-lated standard. The real measurement and test for certain photovoltaic power station in Jiangsu Province isutilized

the reactive power output and control capability is verified

the issue channel mistake of com-mand is found and the voltage exceeding issue of the system is collected. The reason during the test periodis searched through command discrimination mechanism and voltage blocking logic analysis and the im-provement measures in the future is given.
