This type of generator is called "synchronous" because the rotor (rotating part) spins at a speed synchronized with the frequency of the electrical grid. ### Operating principle The operation of a three-phase synchronous generator is based on the phenomenon of electromagnetic induction. It consists of a magnetized rotor that rotates inside a stator winding (fixed part). When the rotor rotates, the magnetic field generated by the magnets (or electromagnets powered by direct current) passes through the stator windings, inducing an electromotive force (emf) that generates alternating current. The rotation speed of the rotor is closely linked to the frequency of the electric current produced, and must remain constant to maintain synchronization with the network. ### Usage situations Three-phase synchronous generators are commonly used in power plants (hydroelectric, thermoelectric, nuclear, etc.) where it is necessary to produce large quantities of electrical energy to power the distribution networks. They are also used in industrial applications where precise control of the frequency and voltage of the energy produced is required. ### Fields of use - **Power Plants**: Large-scale energy production. - **Industry**: Energy supply to large industrial plants that require constant and reliable power. - **Backup Systems**: Critical infrastructures where it is necessary to guarantee the continuity of the electricity supply. - **Cogeneration plants**: Combined production of electricity and heat. ### When and why it is convenient to use it The use of a three-phase synchronous generator is convenient when stable and high-quality electricity production is needed. It is particularly advantageous in situations where: - Tight regulation of frequency and voltage is required. - High efficiency is required in the conversion of mechanical energy into electrical energy. - The grid requires perfect synchronization to avoid stability and energy quality problems. ### Why buy a used Ansaldo Sistemi Industriali 25,000 kW three-phase synchronous generator Purchasing a used three-phase synchronous generator from a renowned brand such as Ansaldo Sistemi Industriali can be a very convenient option for several reasons: 1. **Cost reduction** : A new generator of this capacity can be extremely expensive. Purchasing a used unit can offer significant cost savings. 2. **Reliability**: Ansaldo generators are known for their robustness and reliability. Even when used, a generator of this brand, if well maintained, can provide years of efficient service. 3. **Sustainability**: Buying used equipment can be an environmentally friendly choice, reducing the demand for new resources and the environmental impact associated with the production of new equipment. 4. **Faster Delivery Times**: Used generators can be available immediately, reducing wait times compared to purchasing a new generator, which can take months to produce and deliver. 5. **Proof of Quality**: A used generator, if previously in operation, has demonstrated that it can operate reliably, unlike a new unit that has yet to be field tested. In summary, a 25,000 kW Ansaldo Sistemi Industriali three-phase synchronous generator represents a valid choice for those who need a powerful, reliable and more economical solution than purchasing a new unit, especially in industrial or energy production contexts where quality and continuity of service are crucial.
