What is pitch control?

Pitch control is the technology used to operate and control the angle of the blades in a wind turbine. The system is in general either made up by electric motors and gears, or hydraulic cylinders and a power supply system.

How does pitch control work?

Pitch controls adjust the blades in wind turbines by rotating them so that they use the right fraction of the available wind energy to get the most power output, all the while ensuring the turbine does not exceed its maximum rotational speed.

What is meant by pitch control and yaw control?

Blade angle adjustment and turbine rotation are also known as pitch and yaw control, respectively. The purpose of pitch control is to maintain the optimum blade angle to achieve certain rotor speeds or power output. You can use pitch adjustment to stall and furl, two methods of pitch control.

What is function of pitch control system?

How Does a Pitch Control System Work? A pitch control system’s goal is to both monitor and adjust a wind turbine’s rotor blade angle. These blades — which can be as long as 65 meters or more — are responsible for the turbine’s rotational speed.

Why do we need a pitch control system?

There is a tendency that the Cost of Energy (CoE) leads to more compact pitch control systems where space, weight and not least safety are the biggest drivers for more integrated systems. Need help? Turbine control or turbine retrofit?

How does pitch control work in a wind turbine?

Pitch control is the technology used to operate and control the angle of the blades in a wind turbine. The system is in general either made up by electric motors and gears, or hydraulic cylinders and a power supply system. How does it work? The pitch system is a closed loop drive system.

What do you call a variable speed pitch control?

Pitch control. A variable speed pitch control (or vari-speed) is a control on an audio device such as a turntable, tape recorder, or CD player that allows the operator to deviate from a standard speed (such as 33⅓, 45 or even 78 rpm on a turntable). The latter term “vari-speed” is more commonly used for tape decks, particularly in the UK.

How does pitch control work on a DJ deck?

A typical DJ deck allows the pitch to be increased or reduced by up to 8%, which is achieved by increasing or reducing the speed at which the platter rotates. Turntable or CD playing speed may be changed for beatmatching and other DJ techniques, while pitch shift using a pitch control has myriad uses in sound recording.
