【Abstract】 In order to conduct experimental study for flicker, a decomposed flickermeter model is developed by decomposing the weighting filter of IEC flickermeter. Luminous flux signal acquired from experiments can be input directly into this model to calculate the short-term severity value Pst, which is the index to assess the flicker severity. The feasibility and effectiveness of this model is experimentally verified. The design and establishment process of experimental facility is also presented in the paper. The high-precision illuminance meter is applied to acquire luminous flux signal of the compact fluorescent lamp(CFL) supplied by voltage containing interharmonics with given frequency and magnitude. Experimental studies for CFL light flicker under voltages containing interharmonics with various magnitudes and frequencies are conducted by using the proposed decomposed model. The short-term severity value Pst are obtained, and therefore the interharmonic limit curves for light flicker of compact fluorescent lamp are proposed.更多还原
