Descarbonização da rede (Abrindo caminho para uma rede elétrica descarbonizada)

High-voltage direct current (HVDC) is ideal for bridging the distances between large-scale renewable power generating installations such as offshore wind farms and the load centers they serve. In a multi-terminal configuration, the collecting of renewable power can be com-bined with pan-continental inte-gration of power transmission systems, such as for intercon-necting multiple regional or national AC grids.

In coordination with the con-nected AC systems, HVDC can provide important services for maintaining power system stability under even the most challenging conditions. HVDC thereby plays a key enabler role in the energy transition.

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 ability is becoming increasingly impor-tant as the rising share of renew-able power generation and the fluctuating nature of its power feed-in can lead to a lack of short-circuit power and inertia.

When fossil-fuel power plants are in standby shutdown, synchro-nous condenser solutions use a conventional generator to provide the necessary inertia and short-circuit contribution by means of its rotating mass while also provi-ding or absorbing reactive power.

HV-transmission assets are a critical part to supply high
quality energy to our society. We  have the unique competence as an OEM to render a compre-hensive suite of services to keep your assets in service over decades. This includes spare parts, refur-bishments, digitalization such as SIEAERO, our overhead power line (OHL) inspection technology based on drones and artificial intelligence, consulting and audits – even full service such as operation and maintenance contracts.

Battery Energy Storage Systems are rechargeable batteries that can store energy from different sources and discharge it when needed. BESS consist of one or more batteries and can be used to balance the electric grid, provide backup power, and improve grid stability.

Our Blue portfolio makes it possible to modernize and expand the existing power grids at the highest level of safety and to simultaneously reduce our eco- logical footprint to an enormous extent without having to com-promise on performance and economic feasibility. The combi-nation of vacuum switching technology and clean air insulation reduces emissions while greatly increasing the recycling.
