This type of generator is called "synchronous" because the rotor (rotating part) rotates at a speed synchronized with the frequency of the electrical network. ### 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). As 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 grid. ### Application Situations Three-phase synchronous generators are commonly used in power plants (hydroelectric, thermoelectric, nuclear, etc.) where large quantities of electricity must be produced to feed the distribution networks. They are also used in industrial applications where precise control of the frequency and voltage of the energy produced is required. ### Application Areas - **Power Plants**: Large-scale energy production. - **Industry**: Power supply to large industrial facilities that require a constant and reliable power supply. - **Backup Systems**: Critical infrastructures where continuity of power supply must be guaranteed. - **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, high-quality electricity production is required. It is particularly advantageous in situations where: - Tight regulation of frequency and voltage is required. - High efficiency in converting mechanical energy into electrical energy is required. - The grid requires perfect synchrony to avoid stability and power quality problems. ### Why buy a used 25,000 kW Ansaldo Sistemi Industriali three-phase synchronous generator? Buying a used three-phase synchronous generator from a renowned brand like 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. Buying a used unit can offer significant cost savings. 2. **Reliability**: Ansaldo generators are known for their robustness and reliability. Even a used one, a well-maintained Ansaldo generator 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 the wait time compared to purchasing a new generator, which may take months to manufacture and deliver. 5. **Proof of quality**: A used generator, if already in operation previously, has proven to operate reliably, unlike a new unit that still needs to be field-tested. In summary, a 25,000 kW Ansaldo Sistemi Industriali three-phase synchronous generator represents a valid choice for those requiring a powerful, reliable, and more cost-effective solution than purchasing a new unit, especially in industrial or energy production settings where service quality and continuity are crucial.
