The greatest impact on grid power quality of wind power integration is power fluctuation in range of 0.01Hz–1Hz. Low Voltage Ride Through is also a major technical problem in Wind Power Generation. The SEMS (Superconducting Magnetic Energy Storage System) possess the characteristic of high storage energy density, low loss, fast respond speed and etc, so SEMS is applied in the wind power generation...
This paper presents a novel parts state correction method using image processing. In order to correct state, this paper illustrates the method of how to detect the hole in parts' location and how to calculate parts' deviate angle mainly based on Hough transform. This method is proved to be useful and efficient in practice. The paper is innovative in three facts. First, the matching image is a more...
The utility-interactive inverters can operate in grid-connected and islanded mode. The key technology of dual-mode inverter is to achieve the seamless transfer and reduce the impact of current and voltage to load or grid. A practical grid-connected switch is a physical switch and the switching delay exists. The paper analyzes the influence of the switching delay in detail, that is, there is a uncontrollable...
PurposesThe application of FESTO training system in the design of automatic control system is introduced. With the help of resarch of one example, the real industrial application of the conveying controlled automatically, one convenient design method of pneumatic electrical - pneumatic automatic control system is developed Procedures. Practice proves that using this method is a good way for learning...
Widespread applications of the power electronic-based loads continue to increase concerns over harmonic distortion. This paper therefore proposes a novel fuzzy logic variable hysteresis band current control technique of shunt active power filter, to compensate the harmonics and/or the reactive power generated by nonlinear loads. In this technique, the interference between phases due to the construction...
The three-dimensional power real-time topology and color is the important and indispensable component of the three dimensions of power monitoring man-machine interface. The application of existing three-dimensional power GIS is still relatively rare in real-time color. In the basis of NET and XNA, this paper implements three-dimensional real-time topology and color by using the method of dynamic mapping...
