The spread of wind energy converter is progressing in recent years and its capacity is becoming larger and larger. In order to capture more energy from the wind, it is important to analyze loss characteristics of wind generators for operating speed which is determined dependent on the wind speed. This paper presents a method to evaluate various losses in wind generator as a function of wind speed, which is based on the steady state analysis and thus the calculation can be performed quickly. By using the proposed method, wind turbine power, generator output, various losses, and the total energy efficiency are calculated for three types of wind speed data which are represented by a weibull function.

Recently, wind power generation is increasing in the world. In the wind power stations, induction machines are mostly used as generators. Since induction generators have a stability problem similar to the transient stability of synchronous machines, it is important to analyze the transient stability of power systems including wind generators. Although there have been some reports analyzing the transient stability problem, wind turbine and wind generator are, in most cases, modeled as one mass shaft system having total inertia constant. This paper presents simulation analyses of transient stability of power system including induction generator which is expressed by a two-mass shaft model and analyzes an effect of shaft system modeling on the transient stability characteristics. Simulations are performed by PSCAD/EMTDC in this study.
2 0 0 0 OA 風力と水素を核とするエネルギークラスターの構築
独立系統と離島を対象として風力発電機と水素電解槽から成るシステムを検討した。前者では風力機を並列接続してその出力を電解槽に供給するため、直流出力並列回路に対するDC-DCコンバータ制御法を導出し、次に複数の風力機から成る実験システムを構築し、発電機がそれぞれMPPT制御されかつ電解槽に電力を供給できることを確認した。後者ではディーゼル発電機と負荷から成る小規模モデルを構成し、風力機出力を電解槽に供給し、発生水素を燃料電池に入力して電力と熱を発生し、それを負荷に供給するシステムを設計した。このシステムを小規模系統に導入することにより周波数変動が減少し、CO2排出量も低減できることを確認した。

Recently the wind power generation has attracted special interest and many wind power stations are being in service in the world. In the wind power stations, induction machines are mostly used as a generator. Since induction machines can become unstable during a fault in power system, like a step-out of synchronous machines, it is important to analyze the stability of power system including wind generators. This paper presents a consideration on the stability of induction generators from a point of view of voltage stability.

Recently the wind power generation has attracted special interest and many wind power stations are being in service in world. In the wind power stations, induction machines are mostly used as a generator. Since induction machines also have a stabi problem like the transient stability of synchronous machines, it is important to analyze the transient stability of power system includ wind power stations. This paper presents a model of induction generators, develops methods of power flow calculation and transi stability simulation of power system including induction generators, and presents considerations on the characteristics of transi stability of induction generators on the basis of numerical simulations.
