Abstract
Abstract: While global reinforcement of countermeasures against global warming is required, Japan depends on overseas imports for over 95% of energy consumption. From the resource production site to the domestic final consumption, it is important to continuously build a stable energy supply system. With the accident at TEPCO Fukushima nuclear power plant occurred on March 11, 2011, the expectation for renewable energy is rapidly rising. Among them, the eyes to wind power generation are changing in particular. At the end of 2012, the amount of wind power generation equipment installed worldwide corresponds to 280 nuclear power plants. National Institute of Technology Tsuruoka College introduced a fully independent power supply system by wind power as a part of human resource development project for engineers. In this research, we were able to extract the task by analyzing the power generation characteristics applying Mahalanobis-Taguchi-System (MTS), diagnosing the cause and optimizing power generation efficiency.
Highlights
While global reinforcement of countermeasures against global warming is required, Japan depends on overseas imports for more than 95% of energy consumption
With respect to variations in output characteristics of wind turbines, we will focus on the three items of wind speed, rotor speed, and wind energy from the results of cause analysis and diagnosis by MTS, and the technical views are described below
The factors that cause the wind turbine output characteristics in the compact wind power generation system were analyzed by MTS and the causal parameters were extracted from the analysis results obtained
Summary
While global reinforcement of countermeasures against global warming is required, Japan depends on overseas imports for more than 95% of energy consumption. As a result of a power outage continued at the Great Tsunami caused by the Great East Japan Earthquake that occurred on March 11, 2011, a series of nuclear accidents such as hydrogen explosion and meltdown occurred at the Fukushima Daiichi Nuclear Power Station, and radioactivity was scattered over a wide area. In response to this accident, further stringent safety measures are required, and it is expected that countermeasure and administrative costs will increase [1]. We have worked on optimization of power generation efficiency (high efficiency and output stabilization) by analysis of power generation characteristics applying “Mahalanobis-Taguchi-System (MTS)” to introduced wind power generation and cause diagnosis by application of parameter design
