The randomness of wind energy and its harmonic. Finally, the wind farms also have another uncertainty of forecasting have caused serious problems such as voltage fluctuations, flicker. power quality problems, which restrain the further These typical problems of wind farms will increase development of wind farms. Therefore, it is a hot the loss of electricity equipment, and even lead to topic to research and solve the power quality the wind farm off-grid operation , and can result in problems of wind farms. This paper describes the huge economic losses [1, 2]. Therefore , it is important aspects of power quality problems about necessary to analyze the power quality of the wind the voltage fluctuations and flicker, harmonic, farm, and comprehend its harmonic characteristics, voltage deviation of the wind farm combined with which will contribute to improve the operating the measured data of Baolian wind farm. Finally, conditions and efficiency of the wind farm.In order the loss of a real wind farm is also considered by a to ensure measurement for power quality problems simulation model. and keep the power system stable, Chinese Power

Adopting the connection group structure of Dd0yn11, this paper designs a novel low-voltage (LV) distribution transformer (DT) based on inductive filtering (IF), and verifies the proposed transformer through a comprehensive innovation experiment. Firstly, the functional relationship between valve-side harmonic current and grid-side current was derived according to the winding model, and the filtering features were obtained to compute the impedance between the valve-and grid-side windings. Next, the design calculation was carried out by the engineering magnetic circuit (EMC) method. After that, a three-dimensional (3D) model was established for the proposed transformer on ANSYS Maxwell. The simulation results show that the proposed transformer meets the design requirements on the relevant parameters, and eliminates the harmonic pollution in the grid. Finally, the proposed transformer was proved correct and effective through experiments, and found to stimulate studentsꞌ interest in learning and innovation.

Abstract:The output power and terminal voltage of the fixed speed induction generator fluctuate in the partial load region where the wind speed is below the rated vale, resulting in fluctuations in the grid frequency and voltage. In this paper, a novel pitch angle control strategy has developed by introducing an exponential moving average (EMA) concept from which the controller reference power (signal) can be set for below-rated wind speeds. Therefore, the employed pitch angle controller together with static synchronous compensator (STATCOM), named the unified voltage and pitch angle controller (UVPC), addresses the objective of smoothing the output power and terminal voltage regulation of a wind generator, subjected to below-rated wind speed variations. Moreover, an interval type-2 fuzzy logic technique has incorporated in the pitch angle controller design, since it is more efficient in handling the uncertainties in membership functions and rules than its traditional fuzzy logic counterparts. Simulation results clearly show that the proposed UVPC effectively smoothens out the generator output power and also regulates the terminal voltage at its constant magnitude.
