IEC 60034-3:2020 free download.Rotating electrical machines – Part 3: Specific requirements for synchronous generators driven by steam turbines or combustion gas turbines and for synchronous compensators.The size is 23.4M.
IEC 60034-3:2020 applies to large three-phase synchronous generators, having rated outputs of 10 MVA and above driven by steam turbines or combustion gas turbines. Also included are synchronous Mvar compensators of the same output range connected to a grid for the purpose of exchanging reactive power.

Turbine driven synchronous generators and synchronous compensators shall fulfil the basic requirements for rotating machines specified in IEC 60034-1 unless otherwise specified in this document.
Wherever there is reference to an agreement in this document, it shall be understood as an agreement between manufacturer and purchaser.
The rated conditions of a compensator are basically the same as those of a generator but with different definitions of apparent power and power factor.
—The rated apparent power consists mainly of the maximum continuous reactive output at ated voltage when the machine is overexcited, and of a small amount of active power delivered to the compensator.
—The rated power factor is close to zero, reflecting mainly the maximum reactive power and the losses compensated by the grid.
For compensators, the range of reactive power shall be agreed upon.
