Parameter estimation procedure for the equivalent circuit model of compact fluorescent lamps

• Compact fluorescent lamps (CFLs) consume highly distorted currents and may account for significant consumption on distribution feeders.
• Estimation procedures of the CFL model parameters must be studied in order to predict CFL harmonic current emissions into networks.
• This paper describes estimation procedures of CFL parameters and presents estimation algorithms based on least square techniques and actual measurements.

The spreading use of compact fluorescent lamps (CFLs) in utility distribution systems is leading to increased concerns over power quality because CFLs consume highly distorted currents, which may account for significant power consumption of distribution feeders. For this reason, CFL models and estimation procedures of CFL model parameters must be studied in order to predict CFL harmonic current emissions into networks. This paper describes estimation procedures of CFL model parameters and presents estimation algorithms based on least-square techniques and actual measurements. The estimation procedures are validated with extensive laboratory measurements.
