“…Online plotting functions, controls and meters are also included, so that the user can alter system parameters during a simulation run, and view the results instantly. Especially, if a model does not exist, PSCAD provides the flexibility of building custom models, either by assembling them graphically using existing models, or by utilizing an intuitively designed Design Editor [1,21]. The converters modular on the grid and generator side which are embedded in Fig.…”

“…Meanwhile, with the progress in technology, WPG will be fully competitive with conventional energy power generation. Although wind energy will not play a major role in this new economy in the near term, the mushroom trend in installed capacity over the past years instills that its role will increase over time and wind farms will be operated more and more similar to a conventional power plant [1,5,6].…”

Along with environmental consciousness enhancement, conventional energy depletion, wind energy exploitation is expanding gradually due to the renewable merit, clean without any pollution and vast reserve features. Therefore, wind power generation (WPG) system equipped with Doubly Fed Induction Generators is emerging as mushroom. Larger rated capacity of power unit, the higher tower and the variable pitch are the main scope in WPG system. However, latent trouble will bring about likewise. If a fault occurred, it will be catastrophic for WPG system. Consequently, the technology of fault detection will play a more important role in WPG system. Based on the present status, a novel method is proposed in this paper after summarizing and analyzing the lack of previous methods. Then an example for detecting the inverter fault is studied using PSCAD software. Results indicated that the proposed method is effective and feasible.

“…Indoor laboratory tests showed that the energy recovery system was able to recover 13% of the fan motor power consumption. Wang Chao [3] designed a device for generating electricity by wind energy in driving process. The results showed that: when the vehicle traveled at speed of 90km/h, the designed device could provide electric energy for the pure electric car with 9% of the power battery capacity.…”

In order to increase the driving range of electric vehicles, a lift-drag hybrid vertical axis wind turbine (VAWT) and an air duct were designed in this paper, which could realize the wind energy recovering. The energy conversion theory of the concentrated wind energy was introduced into the design of air duct. The wind speed would be increased by 30% after concentrated by the air duct which was verified through CFX simulation. The simulation of original vehicle model, wind turbine and air duct were carried out respectively in Ansys Workbench. And after adding the wind energy recovery device, the drag resistance coefficient of the electric vehicle is reduced by about 8.84%. Indoor laboratory tests conducted on a scale-up model show the flow fields inside the air duct and the turbine rotational speeds in different wind conditions. Results show that position 3 is the optimal matching position of wind turbine and air duct where the cut-in speed is about 4.78km/h and the maximum rotational speed of wind turbine is 458rpm.
