Mechanical energy is converted to electrical energy by the wind turbine generator. Wind turbine generators are unique among the several types of generating units that are connected to the electrical grid. The generator must work with a power source that provides highly variable mechanical power.
The electrical machine that generates electricity is the Wind Turbine Generator. A low-rpm electrical generator is at the heart of any wind power system, transforming the mechanical rotational power supplied by the wind into useful electricity to power our houses.
Due to the fluctuating nature of wind power, operating the WTG at variable speed is advantageous since it decreases physical stress on the turbine blades and drive train while also improving system aerodynamic efficiency and torque transient behaviours.
The field is on the stator and the armature is on the rotor in traditional DC machines. The stator is made up of several poles that are either activated by permanent magnets or DC field windings.
The lift force is greater than the drag force, causing the rotor to spin. The rotor is connected to the generator either directly or by a shaft and a series of gears that allow the generator to be physically smaller by speeding up the spin.
The wind creates a turning force when it passes over the blades. Inside the nacelle, the rotating blades cause a shaft to revolve, which then goes into a gearbox.
The Global Wind Turbine Generators Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2027, registering a CAGR of XX% from 2022 to 2027.
The Haliade-X, the world’s largest and most powerful offshore wind turbine, was revealed today by GE Renewable Energy. Because a single turbine may produce more power, the total number of turbines in the farm can be lowered, resulting in lower capital expenditure for the balance of plant and lower project risk as the installation cycle time is reduced.
The SG 10.0-193 DD, the company’s first 10+ MW offshore wind turbine, was introduced today by Siemens Gamesa Renewable Energy (SGRE), the world’s leader in the offshore business.
In one 10 MW turbine, the new SG 10.0-193 DD combines experiences and knowledge from five generations of proven direct drive technology. In the offshore wind energy sector, this is a showcase of strong performance, quick time-to-market, and minimal risk. Vestas India has announced the launch of a new low-wind turbine generator.
Vestas India, a subsidiary of Danish wind turbine maker Vestas Wind Systems, is trying to grow its presence in India and develop products tailored to the Indian market.
Rotor monitoring system (RM-S).The stresses placed by bending moments on the rotor blades of wind turbine generators are measured using the rotor monitoring system (RM-S).
With the right closed-loop control, it may be utilised to conduct predictive maintenance applications, increase plant working time, or proactively reduce loads.
To achieve this, the inner side of the rotor blades of a wind turbine generator are attached towards the base of the blade with high-precision but durable sensors based on strain gauges.
The custom designed strain gauges and a controller from Phoenix Contact with PLCnext architecture make up the solution’s foundation. High-resolution, directly coupled Axioline F modules link the controller to the rotor blade sensors.
The sensor wires and power supply have the appropriate safety mechanisms fitted to safeguard the system from overvoltages and lightning strikes. To enhance the system for direct, wireless connection, a modem is an option. You may interact with the system through PROFINET, Modbus/TCP, OPC-UA, or CANOpen.
The controller receives the measured variables and preprocesses them before sending you signals in physical units. Additionally, variables arising from the strain signal are determined, including the bending moment and material tension.
Additionally, mean values, minimum and maximum values, signal variance values, and statistical parameters are obtained.Limit values can also be provided so that if they are exceeded, automated notifications can be issued through one of the bus interfaces.
The higher-level controller can simultaneously access the data produced in that manner for signal scanning. All raw data may be buffered to an SD card on a sFTP server in CSV or binary format, where it can then be retrieved by a separate system for additional analysis.
To achieve this, the RM-S gives you an HMI-based commissioning interface that is based on web technology. additional than a browser, you don’t need any additional software. You may configure the system, view the measured results, and keep an eye on the system status using the HMI.
