Three-phase cage induction machines, configured in two series-connected and one isolated (TSCAOI) configuration, have earlier been proposed for variable speed single-phase electricity generation. Although steady-state characteristics of TSCAOI generators have previously been investigated, both the nature of torque due to unbalanced operation and its impact on overall performance are yet to be analyzed...
A multiple-model adaptive control algorithm is developed for wind power forecasting based on three forecasting models for very-short term wind power prediction. The performance of the three models and the proposed approach is verified in a wind farm in North China. The case study indicates that the proposed approach can provide reasonable very-short term wind power prediction and outperforms the other...
This paper investigates the steady-state characteristics of 3-phase cage induction machines that use two series-connected and one isolated (TSCAOI) phase winding configuration to generate single phase electricity. In this configuration, one phase-winding excites the machine while the remaining two in series generate electricity at constant frequency under varying rotor speeds. The steady-state model,...
Through using the concept of deontic logic and classifying different types of policy conflicts, an effective policy conflict detection method was proposed. The main idea of the method is based on the research on the existing policy conflict detection methods. Then, a powerful conflict library in the detection process is built. The library is combined with the static and dynamic detection of policy...
This paper proposes a practical and effective method base on weather patterns for producing 15-minutes short-term prediction of photovoltaic generation with a prediction horizon of 24 hours. Two different radiation prediction models are examined for two different weather patterns. In the clear sky model, the surface radiation is predicted by calculating the cutting plane instantaneous intensity of...
In order to analyze the dynamic response of the underground pipeline during the earthquake, a numerical simulation of pipeline underground under three-dimension earthquake uniform activation through large mass method by employing the finite element software midas gts. Contact pairs are established between pipe and soil surrounding, and viscoelastic artificial boundary is adopted to simulate transmission...
Based on the research work of network-based intrusion detection system testing principles and conditions, this paper seeks the solution to unify practical research content and GA/T 403.1-2002 reasonably. Precisely, a more comprehensive and reasonable network-based intrusion detection system testing methodology as well as a complete testing work flow is proposed. Based on these foundations, design...
