As gas and steam power generation plants approach the end of their operational life, plant owners face a challenging decision between upgrading or retiring the plant. Retiring a power generation unit ...

Alternating-current (ac) generators are commonly referred to as synchronous generators or alternators. A synchronous machine, whether it is a generator or a motor, operates at synchronous speed, that ...

As more wind and solar generation is added to the power grid and large coal and nuclear plants are retired, a reduction in reactive power is becoming a concern. Underutilized gas and steam turbines ...

As more renewable energy sources and battery storage units are specified and incorporated into power systems, consultant specifying engineers are faced with many challenges that could impact the ...

A direct current is applied to the rotor winding of a synchronous generator to produce the rotor magnetic field. A prime mover causes the generator rotor to rotate the magnetic field in the machine. A ...

Synchronous generators are the core of a number of power plants. They are used for electricity production. Pole coils, in turn, are a vital component found in all synchronous hydro generators. They ...

The proposed GFM PVSG concept can transform today's GFL PV plants into GFM PV plants, thereby offering a cost-effective approach forward. Figure 1. Grid forming PVSG: Parallel a GFM storage system ...

A group of researchers in Australia has outlined a new methodology to determine the minimum power rating of energy storage systems (ESSs) used for emergency under-frequency response. The ESS size must ...
