Valves
To achieve the space constraint and weight reduction, cartridge valves are used in the wind turbine power packs.
The screw-in cartridge valves, solenoid-operated cartridge valves, and proportional directional control valve are fitted in the manifold of the hydraulic power pack of the windmills.
Check valve (cartridge type) is also known as a non-return valve. The function is to allow the flow of oil in one direction and completely block in the other direction
The relief valve limits the maximum system pressure in a hydraulic circuit. This normally closed valve opens to relieve the pump flow back to the reservoir when the preset pressure is reached. This prevents the system pressure from rising above the set value.
Solenoid operated poppet valves are in types of 2 way 2 positions and 3 way 2 position valves are used.
When the solenoid coil is not energized, the oil flow is between one path, that will be changed to another path when the solenoid coil is energized.
The proportional valve is the most important and sensitive component in the entire hydraulic system. The proportional valve is used for pitch regulation in a closed-loop position-controlled mode. The control computer generates an electrical signal to set the blade angle depending on the wind speed. The proportional valve receives this signal and positions the pitch cylinder and operated through the linkage mechanism of the blades.
The closed-loop mode constantly monitors this position and automatically corrects the blade angle in case of drifts.
A normal solenoid valve has finite flow paths like P – A, P – B which can be activated by energizing solenoids
PRESSURE SENSOR
In a hydraulic circuit, the oil pressure will be maintained to the required pressure. If the pressure drops (or) pressure goes up, it will create a problem and damage the parts and valves. So, the pressure sensor is fitted in the circuit and pressure will be monitored.
POSITION SENSOR
In a windmill, to get the maximum wind efficiency, the turbine blades will be pitched. This blade pitching operation will be done by a hydraulic pitch cylinder which actuates the pushrod to rotate the blades to the correct position. For the accurate movement of the cylinder piston, the Linear Position Sensor is required. This sensor indicates the position of the piston and indicates how much movement has been done to blade pitching.
TEMPERATURE SENSOR
In Gearbox and Hydraulic power pack, the oil will get heated due to continuous working. Due to the rise in temperature of oil, it creates damages to the gear, valve failure and oil itself lose its properties. To avoid this, the temperature of the oil is to be sensed and monitored. By receiving this temperature indication, the cooling system will work and cool the temperature of the oil. For the above purpose, the temperature sensor is used in windmills.
LEVEL SENSOR
In a gearbox and power packs, the oil level to be maintained to the required level. If the level of the oil is not maintained, it leads to pump failure and gearbox failure. So, for maintaining the oil level, sensors are used. If the level goes beyond the minimum level, the sensor will indicate the level by signals and it will shut down the machine till the oil is filled.
SPEED SENSOR
The speed sensor is a device that tells the speed of a rotational part. In wind windmills, the rotational speed of brake disc, Generator, Blades, and Gear Box are needed. To find the rotational speed of the components, this sensor is used.
VIBRATION SENSOR
In a windmill, if any part or whole windmill starts to vibrate due to any specific problem, the windmill has to stop and the message has to be displayed on the screen. For these, a vibration sensor will be fitted. If measures the charges of the velocity of a given component. Any vibration will reflect the change in velocity, which will produce an electrical signal.
