As a man-made pollutant to the ionospheric electromagnetic environment, power line harmonic radiation (PLHR) is widely known in these years. It is urgent to conduct research of the influence of PLHR on ionospheric state parameter variation. Based on the observed data of instrument for detection of particles (IDP) onboard DEMETER, by combination analysis on self-orbit and revisiting orbits of PLHR, we statistically studied the variation of pitch angles and energetic electron fluxes of low, middle and high energy bands before and after 72 PLHR events detected in the ionosphere above China. The results show that before PLHR a few events show pitch angle scattering, and the energetic electron fluxes of low energy band tend to decrease. This may be due to the influence of PLHR, or due to this state variation of ionospheric energetic electrons which leads to the easy detection of PLHR.
