IMD 100 RELIABLE PITCH DRIVE

Pitch system design and technology Reliable Pitch Drive In modern wind turbines, the pitch system is the only brake capable of stopping the wind turbine during operation. This makes the pitch drive a safety-critical component. Pitch Design DEIF designs pitch systems to individually match the specific wind turbine design in order to optimise the operation under the following conditions; high, medium, low wind and extraordinary situations such as lVRT (low Voltage Ride Through) conditions and emergency stop. Our R&D teams base their system design on the load data and aerodynamic characteristics...

»You can easily put a blade into high wind, but if you don’t pitch correctly, you can destroy the turbine.« Jacob Danielsen Product Manager DEIF Wind Power Technology high. In such locations, you don't want to have mal-function or too much service. Model based design and dynamic model Reduce risks of design failures and R&D resources from design to implementation. DEIF has a specialized team for Model Based Design and control for the purpose of supporting customer design teams with Dynamic Link Library, (.Dll). By including .Dll in your mechanical design to verify the loads and performance. New...

IMD 100 Pitch drive built to last The Integrated Motor Drive, IMD, has been developed on the basis of DEIF’s decades of accumulated knowhow about the entire wind turbine and its pitch systems. With its integrated motor solutions, the IMD reduces cabling in your system and provides maximum reliability at minimum cost. Engineered to your application, the IMD is bound to become your preferred choice for pitch and yaw control. t PATENT PENDING IMD comes with components such as I/O, ballast resistor, EMC filters, choke and power supply and therefore eliminates the need for a variety of external components....

Functional safety The IMD is a critical function in electric pitch systems, controlling the blade angle during turbine operation and in safe stop situations. the IMD complies with the ISO 13849 safety standards due to the failsafe hardware resulting in a high MTTFd and high performance level PL. offering redundant safety chain I/O, automatic safety homerun function and RFE/RUN for direct hardware control, the drive has been designed to provide the highest possible safety. The IMD complies with performance level d on single blade and performance level e on 3 blade system level. Pitch System

IMD 100 All-in-one pitch drive Power Supply Mains connection & EMI Filter IMD has a failsafe motor brake supply output fully controlled and monitored to detect wire break or short circuit. Some of the big components in standard drive applications is the EMI filter and line choke which protects the grid from the electric switching power noise and the mains breaker disconnecting the drive from grid. The IMD contains a built-in switch mode power supply for the internal and external functions, all supplies are galvanically isolated to prevent short circuits on one supply from causing malfunction...

IMD 100 Easy configuration and set-up Interfaces – CAN/CANopen,USB Configuration & Service The primary control and command interface is CAN or CANopen. The CAN port is connected directly to the pitch motion controller located in the hub or turbine controller over the slip rings. The software also contains trending functionality similar to an oscilloscope, displaying all measured and calculated values. the communication and configuration of the IMD is carried out utilising one of many communication interfaces. For easy installation, configuration and test a USB service port is place on the front,...

Mechanical & electrical Installation In the turbine hub, the rotation and vibration can easily result in wire break or loose wires. All IMD connections are spring loaded to comply with the mechanical challenges and keep the same torque on the wires. D-sub connectors are secured by screws and give EMC protection to the communication signals The compact design of the IMD allows for installation in any pitch cabinet and contains all electrical connections and interface in only two directions. This makes it mountable in the corner or the side of the cabinet with full access to all terminals. Mechanical...

Pitch Drive Features The Integrated Motor Drive, IMD 100, is a robust microprocessor-based drive containing all necessary functions for functional safety, motor control, sensor input and distributed I/O. The IMD is intended for wind turbine pitch systems interfacing to a Pitch Motion Controller or directly to a wind turbine main controller. The IMD 100 is a motor drive designed to fit into the small space in pitch panels installed in the hub. Climate and operation conditions are among the toughest in any application. Continuous rotating, continuous vibration, continuous temperature change 24/7...

Maximum reliability for remote areas Cutting-edge pitch design for Sewind Both in terms of the technology the solution was based on and the attitude of the supplier, SPERI singled out DEIF Wind Power Technology as a possible partner, and we decided to go for a full-scale test by ordering prototypes for real life testing. Initially, we were intrigued by the open attitude of DEIF’ Mr Xun says. ‘DEIF’s openness towards sharing the technology so that together we were able to develop a solution which Sewind could continue the development and maintenance of was exactly what we was looking for. In 2011,...

Cutting-edge pitch design for Sewind »We were looking for a more open partner in terms of willingness to share the technology so that we could optimise the entire design in a teamwork.« We decided to make the first solution from DEIF based on traditional energy storage technology, and we have now developed it into a cutting-edge solution based on ultra-cap technology', and Mr. Xun adds with a smile 'that is the benefit of working with a partner mastering several technologies, it simply gives us full freedom of choice'. 'In addition, the choice becomes a safe one given the fact that DEIF can also supply...
