The use of compact fluorescent lamps (CFLs) in utility distribution systems is spreading due to energy consumption concerns. This can damage system power quality because CFLs are nonlinear harmonic injecting loads. For this reason, CFL modeling must be studied to predict their harmonic current emissions into networks. This paper presents a CFL model for calculating these emissions, as well as a simple estimation algorithm for determining the model parameters from experimental measurements. They are both validated with laboratory tests.
