In order to improve the wind power penetration, control the volatility of the wind, this paper has carried out the research on the integration of energy storage and generating wind turbine system model. The idea has been gained based on the analysis of the current wind turbine system, wind turbine system with low wind speed starting and running and the integration of energy storage and generating...
Through the analysis of wind turbines, photovoltaic systems, fuel cells and high frequency micro turbines, their models in power flow calculation were established in this paper. Moreover, a novel power flow algorithm based on back/forward sweep technology for radial distribution networks considering Distributed Generation (DG) is proposed. The algorithm develops a reactive power compensation method...
A remote video monitoring system is built based on embedded web server by using moving target monitoring. In the system a novel algorithm based on symmetric difference and background difference is proposed. The system will alert when it detect and recognize the illegal invasion in the scope of monitor. Thus the intelligent monitoring system is achieved. Experiment results show that the new algorithm...
GPS is a new generation of satellite navigation and positioning system which is most widely applied at present. This article introduces briefly the receiving and analysis of GPS data, and the application of GPS positioning, path analysis and navigation module in power inspection instrument software.
At present, the fuzzy control method is a more advanced and reasonable control method. This paper adopts the fuzzy control method of UPFC parallel voltage control and series power modulation to solve the active and reactive power flow control effectively, so that the transmission lines can transmit more power with smaller loss.
This article firstly introduces current situation of network security. Then a brief history and process of network attack have been stated. Methods to launch network attack and principles against network attack have been brought to the notice in detail. Through this paper, people can learn how to build safer network environment.
The dynamic compensation in rural distribution network can not only reduce the active power loss of certain lines and improve power factor, but also ameliorate each nodal voltage level. However, the switching control of dynamic compensation capacitor always depends on the parameters of installation node, namely, local control. There is no uniform scheduling, lacking a full consideration to reactive...
In order to achieve meticulous management in reliability of power supply, the system of MBO (management by objective) is studied based on power distribution network GIS platform. First, a new coding method which used GUID (Global Unique Identifier) technology is integrated in spatial database design. The codes can describe completely the topological structure of distribution network which is necessary...
This paper used the multi-class classification for support vector machine and combined with the good amplitude-frequency characteristic of Fourier transform,the good time-frequency characteristics of wavelet transform and the excellent statistical learning ability of support vector machine to make the classification and recognition to the disturbances of power quality. Mathematical modeling for the...
