“…a WTG is not able to produce rated power, therefore the WTG has to capture as much wind power as possible. To do this maximum power point tracking (MPPT) [9 ] is used to control the system operation, and the output characteristic follows the blue line in Fig. 1.…”

“…In this situation both rotor speed and generator speed decelerate. The electromagnetic torque will be reduced to maintain the generator speed [9 ] and fault pattern 2 will occur in Mode 3 of the P-N diagram. Considering a situation where gusts cause fluctuation of the generator speed in Mode 4 [8], if a pitch system failure occurs then the pitch angles will increase and the aerodynamic torque will decrease.…”

Supervisory control and data acquisition (SCADA) data has been widely applied to identify abnormal conditions in wind turbine generators (WTG). One approach was to apply Artificial Intelligence (AI) to SCADA data, comparing the predicted power output of a WTG and its actual output and using the prediction error as an indicator to detect faults. However, complicated training processes limit its application. This paper presents a normal behavior model (NBM), based on power output-generator speed (P-N) curve, to analyze SCADA data from modern pitch regulated WTGs for detecting anomalies. Through analysis of the operational characteristics of the pitch regulated WTG, it is found that inaccuracies in wind speed measurement, the inertia of the rotor, yaw and pitch misalignments, and air density fluctuation may affect the performance of the power curve monitoring algorithms. This paper shows that under normal conditions the P-N curve based NBM performs better when fitting the SCADA data to WTG output under normal conditions than the power curve. Results demonstrate that it can give alarm to forthcoming faults earlier than the existing condition monitoring system (CMS).

In this paper, an optimal rotating speed tracking method is proposed for doubly-fed induction generator (DFIG) wind turbines. The method employs a fuzzy logic controller to capture the maximum wind power. The generator output power increment, rotating speed increment and the judgment of optimal speed direction signals are all adopted in fuzzy logical system to improve the performance of the conventional method to a certain extend, and simulation results indicate the effectiveness of the proposed method. 1926 978-1-4799-7016-2/15/$31.00 c 2015 IEEE
