4.4.1. Synchronous generators
Synchronous generators are the basis of overall power generation. They are used in thermal power stations in conjunction with steam turbines as turbogenerators. Their range of performance extends up to 1500 MVA and a voltage of 10.5 kV. The turbines of water power stations operate at lower speeds as steam turbines. The adoption of synchronous generators along with a 50 Hz network presupposes the employment of multi-pole machines which come as salient-pole machines. Water force generators (hydrogenerators) are also constructed for relatively low speeds up to powers of 500 MVA.
