AC voltage stabilizer SVC PLUS® FS

dynamic

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. Frequency and voltage support for dynamic grid stability By using a bulk number of supercapacitors, the new SVC PLUS FS® (E-STATCOM) is a cost-efficient, compact solution that can emulate system inertia by boosting high active power into the grid when needed. It also 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.
