摘要

This paper presents simple methods of determining parameters of interior permanent magnet (IPM)rnsynchronous generator such as magnet flux (λ_M), d-axis inductance (L_d) and q-axis inductance (L_q)ofrnIPM synchronous generator, which are used to control the wind turbine generator. These methods are simplernand do not require any complex theory, signal injection or special equipment. Moreover, a sensorless speedrnestimator is proposed to estimate the speed of the generator without using speed sensor. The measuredrnparameters are used in this speed estimator. The elimination of speed sensor will enhance the system robustnessrnand reduce the design complexity and system cost for a small-scale wind turbine considered in this paper. Therneffectiveness of parameter measurement methods and sensorless speed estimator is demonstrated byrnexperimental results. Experimental results show that the proposed speed estimator that uses the measuredrnparameters can estimate the generator speed with a small error. Copyright © 2014 John Wiley & Sons, Ltd.
