摘要： A communication control portion (11) performs most of communication processing performed by a communication apparatus (1). The communication control portion (11) also executes communication with another communication apparatus (1) using a communication parameter determined by a communication parameter determination portion (13). A transmission line estimation portion (12) measures characteristics of a transmission line (2) at a predetermined timing and regarding a predetermined section, and estimates the state of the transmission line (2). The communication parameter determination portion (13) newly generates an optimum communication parameter from a plurality of communication parameters obtained based on an estimation result obtained on the transmission line (2) by the transmission line estimation portion (12).

摘要： A control apparatus C of a horizontal axis wind turbine apparatus WTG calculates the value en of a pitch angle command for each blade based on the rate of change ΨD of the azimuth angle Ψ of a Nacelle N and the rotor azimuth angle of the blades B1, B2 and B3, causes the rotor R to generated torque around the yaw axis by periodically controlling the angle change of the pitch angle of the blades B1, B2 and B3, and using that torque, controls the rate of change of the azimuth angle of the nacelle N. The value of that angle change is calculated as a value that increases as the inputted value of the rate of the change ΨD increases.

摘要： To provide a horizontal axis wind turbine capable of reducing flutter, and by extension, reducing the load on the wind turbine, without controlling the yaw, regardless of the direction of the wind relative to the nacelle. When the wind speed is above a specific value, the yaw angle of the nacelle is held constant, the blade pitch angle is controlled according to the yaw angle Y of the wind direction relative to the nacelle, and the rotor is allowed to rotate freely. Even when the yaw angle of the nacelle is held constant, allowing the rotor to rotate freely makes it possible to reduce the load by avoiding flutter.

摘要： The variation cycle L of the characteristics of a transmission line is divided into a plurality of sections (n sections), a procedure is repeated in which transmission line estimation is performed for only one section among n sections in one beacon period, and thus transmission line estimation is performed for all of the n sections. The beacon period T is set based on (T=L×m/n), where n is an integer that is 2 or larger, and m is an integer that is n or larger and whose greatest common measure with n is 1.
