GE CR2962E1A4 Plugging Switch 1600 RPM Max Speed Flange Mount

The PSPP Linthal was commissioned and handed over to

operator AXPO in 2016 and is producing energy since then.

The 1000MW PSPP is one of the most advanced

hydroelectric power plants in the world.

It is equipped with four rotating machines of 250MW each.

where the decision was taken to use the variable speed

technology to improve operation behaviors and increase the

advantages in regard of efficiency in full load and especially

the significant improvement in part load operation.

Power Conversion’s scope includes:

• Four 48/48MVA converters for the variable speed asynchronous machines

• Four excitation transformers 18/3.0kV; 28MVA

• Control excitation equipment to start-up the machine and synchronize the

units to the grid

• Overvoltage control protection (crowbar) for rotor of the machine

• Low voltage ride through (LVRT) ability according to Swiss grid code

A Safer and Cybersecure Substation

Transmitting the instrument transformers´ measurements digitally

through optical fibers eliminates the risk of inadvertent mishandling

of the current and voltage circuits and makes the relay room a safer

work environment, eliminating hazards and reducing the risk of

personnel injury.

The MU360 complies with the main standards for digital

substation IEC 61869-9. IEC 61850 edition 2.1 and IEC 61869

13. which guarantees its interoperability and compliance to the

requirements for being the physical to digital interface of modern

digital substations. Furthermore, measurements of each CT/VT

set may be broadcasted in protection and power quality profiles,

allowing multiple Protection, Automation and Control applications

to consume the data without needing extra footprint for acquisition.

To ensure MU360 have all this connectivity in a cybersecure way, it

has been designed according to IEC 62443 and have all capabilities

described by SL2 of this standard, including RBAC, secure boot and

signed firmware.
