SVC PLUS FS® (E-STATCOM)

As the infeed of power from renewable sources continuously replaces conventional synchronous power generation, the grid frequency is getting more sensitive due to the reduced amount of rotating machines. Now grid operators are faced with the challenge to provide sufficient system inertia of synchronous generators with high rotating masses to stabilize the grid.

A SVC PLUS FS® (frequency stabilizer) can solve this challenge as it is able to emulating system inertia by boosting high active power into the grid when needed. In addition it offers voltage support by means of reactive power compensation.

While grids are undergoing fundamental changes in terms of power generation, renewable infeed and ever-growing demand, power quality and dynamic grid stability are at risk due to less synchronous power generation.

The grid frequency is balanced to 50 Hz or 60 Hz by parity of power demand and generation. The frequency must be kept within specific limits, even in the event of an imbalance: for example, from a disturbance. After a fault, the frequency can only be stabilized by an inertial response from generator-turbine sets. The mechanical kinetic energy defines the frequency drop after disturbance until the operating reserve is activated after several seconds by the primary frequency reserve (PFR). Fewer rotating machines result in shrinking instantaneous reserves, which increases the risk of exceeding critical frequency levels. This may lead to load rejection or a blackout. Grid operators are forced to keep power plants in operation in order to preserve the instantaneous reserve or to optionally invest in additional primary reserve. Some source of fast frequency response (FFR) is urgently needed to cover the gap between inertial response and operating reserves.

In challenging times like ours, grid operators need versatile resources that give them options not only to react, but to act proactively. At that, with SVC PLUS FS®, operators can be sure of a reliable, economical and space-saving solution with many advantages in terms of response time, control accuracy, and economic impact.

While every power grid and every large industrial consumer has specific challenges in terms of power quality, active and reactive power compensation, and grid stability, our customized SVC PLUS FS® turnkey solutions answer these challenges from a single source, including customized consulting.

From technical clarifications to on-site support and turnkey solutions, our service portfolio helps you optimize your assets and their performance throughout their entire service life – with comprehensive solutions from just one provider.

Control & Protection (C&P) systems are key to managing power flows and protecting grid components in HVDC and FACTS plants. Both tasks have to be considered in light of increasingly complex grid architectures and fluctuating power infeed from renewable energy sources. For many Transmission System Operators (TSO) and Distribution System Operators (DSO), this leads to three major challenges: first, fast reaction to market needs and short lead time of the C&P system. Second, reliable and secure operations throughout the entire lifecycle while safeguarding low Total Cost of Ownership (TCO). And last but not least, the C&P system should be easy to expand for new solutions and services. This is crucial in order to cope with the ongoing transformation of the energy system and to leverage the potential of future innovations. With our new modular C&P platform Grid Flow PLUS, we’re addressing all of these challenges.
