Description

Parallel connected synchronous condensers are mainly used for providing short-circuit power and inertia. They also help to stabilize the network through voltage recovery during faults. This becomes increasingly important with the rising share of renewable power generation that leads to a lack of short-circuit power and inertia. Due to the fact that conventional power plants are shut down, synchronous condenser solutions use a conventional generator to provide the necessary inertia and short-circuit contribution by means of its rotating mass while also providing or absorbing reactive power. Proven solution to stabilize the grid A synchronous condenser provides short-circuit power, inertia, and reactive power for dynamic loads. Siemens supplies a broad range of generators up to 1,300 MVA at full speed. Inertia and short-circuit power are key elements of grid stability – yet their availability is shrinking. This is caused by the addition of renewables-based power generation to the energy mix, phase-out of thermal power plants, new HVDC systems, and the extension of power supply systems to remote areas. All of this influences the stability of transmission networks, resulting in a worldwide renaissance of the synchronous condenser. The Siemens synchronous condenser solution comprises a horizontal synchronous generator connected to the high-voltage transmission network via a step-up transformer. It is started up and stopped with a frequency-controlled electric motor (pony motor) or a starting frequency converter.
