Challenges of Real-Time Parameter Estimation of a DFIG using Synchrophasors

• This paper explores the challenges faced during the utilization of synchrophasors received from PMUs in order to estimate the parameters of a DFIG in a real-time. PMUs are installed at the stator and rotor terminals of an 11-KVA DFIG, in order to provide high resolution synchrophasor data at a reporting rate of 50 msgs/sec. These synchrophasors are processed in real-time using an embedded controller in order to measure and estimate the internal parameters of the generator, i.e., magnetization and leakage inductances. Closed-loop variable speed drive, active power and reactive power controls are implemented for the DFIG. This paper discusses the laboratory setup, control and parameter estimation experiments carried out on the DFIG. The testing process, challenges faced, and overall experimental findings are also presented.
