SYNCHRONOUS CONDENSERS

SYNCHRONOUS CONDENSERS Synchronous condensers, also called synchronous capacitors or synchronous compensators, are synchronous machines which can provide voltage regulation, reactive power, short circuit power, and inertia to the grid. They play a key role due to the increased energy generation by renewable sources and shutting down of conventional power plants that lead to a worsening of electricity supply services, voltage quality and grid stability. A strategic deployment of synchronous condensers stabilizes the grid and helps to reduce the risk of blackouts. Simple and very reliable industrial...

Stand alone package Stand-alone packages are particularly useful for grid nodes where power electronics or renewable energy sources are connected. Based on the shaft inertia and electrical parameters required by the grid, this package is configured by combining standard turbo generators with minor adjustments (e.g., thrust bearing, phonic wheel, etc.), or using as alternative a fully tailored salient pole machine. A flywheel can be supplied to provide the best match with the specific project requirements. With adding a flywheel, the increased inertia will contribute to the reduction of frequency...

Power Plants with synchronous condensing capacity In conventional, combined or open-cycle plants, the driven generator is decoupled from the turbine by a clutch and operated as a condenser. This solution is suitable for Customers needing to supply reactive power to the grid and no active power (turbine not in operation), as well as to reconnect the turbine in the event of active power demand, ensuring the maximum level of operating flexibility for the Customer. Two operating modes are therefore possible: • Power Mode (turbine engaged) • Synchronous Condenser Mode (turbine disengaged) Condenser...

Retrofit solutions for existing power plants Ansaldo Energia provides full support to convert existing or obsolescent power plants to synchronous condensing facilities, adding new value to present assets. We can tailor the most suitable option according to Customer needs, ranging from the easiest solution, i.e. mechanically decoupling the turbine and using the generator as a stand-alone package, to more specific ones such as converting the turbine shaft into a flywheel or other, more impacting, solutions.
