Research of the impact of voltage quality and reactive power configuration for shock loads connected into distribution network

This paper proposes three dimensions of characteristics to describe the shock load, including reactive power, time, rate of change, then established the simulation model to did deep analysis on the impact of the voltage quality problem for shock loads connected into distribution network, it focuses on comparing the different dimension characteristic due to the difference of the impact of the voltage quality problem, finally proposed the basic principle and advices for shock load access, and it plays a guiding role in reactive power configuration for shock loads connected into distribution network.
