The PCS6000 provides reliable operation in the harshest environments thereby minimizing maintenance

Medium voltage converters for large wind turbines 

 The growing importance of regenerative energy is accompanied by a rise in the demand for wind power. Wind turbines are today attaining such high power ratings that a medium voltage system is the optimum choice. It allows a higher energy production through reduced losses in the electrical drivetrain and lower installation costs by eliminating expensive cable runs

Perfect match for large-scale wind turbines

ABB’s medium voltage wind turbine converter is the perfect match for large-scale offshore wind turbines. Available up to 15 MW, it can be operated with permanent magnet and induction generators. Its compact footprint allows nacelle or tower installations.

Lowest cost of energy

The PCS6000 helps to utilize the full potential of wind energy, reliably and economically. It lowers the levelized cost of energy (LCoE) through maximum availability, high efficiency, advanced grid code compliance and easy maintenance.

Technology proven worldwide

The procedure for replacing the semiconductors in the VLM is similar but not exactly the

same as the procedure described in section 10.6, Replacing components in POU, page 139.

In the VLM there is only one stack instead of three, but the figures shown in section 10.6,

Replacing components in POU, page 139 apply in principle.

1. Switch off MCB -Q401 to interrupt the 3AC 400 V input voltages of the AC/DC converter

(24 V power supply).

2. On the UPS -G402 turn the selector switch “Bat.-Select” to “Service”, then back to “7.2

Ah” (Fig. 8–11 in section 8.8, Replacing PECINTM, page 97) to interrupt the 24 V battery

supply voltage (the yellow LED “Bat.-Mode” must be dark).

3. Take the pressure loading gauge from its storage place and insert it completely under

the tension jack of the stack.

NOTICE The pressure loading gauge must be inserted completely before the stack can

be released. Otherwise the tension jack can break.

4. If an IGCT is to be changed loosen all 4 fixation screws of the gate unit fixations using a

5 mm Allen wrench to make sure that the gate unit fixation can move freely in vertical

direction.

5. Release the stack by loosening the clamping screw counter-clockwise using the socket

wrench with 12 mm Allen socket.

6. Enter a stabilizer plate in the bottom of the stack.

The PCS6000 wind turbine converter is based on ABB’s medium voltage frequency converters which are installed in thousands of applications worldwide. With their excellent reputation for reliable operation in the harshest environments, the converters are used in industrial and propulsion drive systems, railway grid entities, static VAr compensators, battery storage, tidal 

power plants and many other demanding applications. The first PCS6000 Wind was delivered in 2006.

The ABB approach – more than delivering a product From the early evaluation phase of a new wind turbine to final operation in the wind farm, ABB provides first-class customer consulting, support, training and services. ABB’s converter specialists are experts in all aspects of the electrical system and will build a drivetrain that functions perfectly – from the generator through to grid integration. ABB’s life cycle management involves a highly qualified service team and supporting software tools for remote monitoring. They will maximize the value of the equipment by maintaining trouble-free operation and ensuring maximum availability.
