Rotating Grid Stabilizer Conversion for grid stability

With the rising adoption of renewable energy, traditional power generation methods are utilized less, and generators are being shut down. Once these generators are shut down, their role in providing rotational inertia, short circuit power and voltage control, to help balance the grid system disappears with them also. Grid stability is, therefore, a vital consideration for transmission and distribution network operators, with increasing renewable penetration.

Siemens Energy offers Rotating Grid Stabilizer (RGS) Conversion solutions leveraging the company's engineering expertise and service capabilities. The RGS Conversion comprises complete solutions for converting existing power plant equipment into synchronous condensers, from engineering to installation and commissioning.

Traditionally, grid stability is achieved through the dependence on the system strength and system inertia. System strength refers to the ability of the electricity grid to recover intact from major disturbances and it is provided by the short-circuit power of the generator or synchronous condenser. The same generator also provides system inertia which is critical to maintaining a steady frequency in the grid. And no matter the source of generated power, electrical grid systems rely on both for grid security, safety, and reliability.

Siemens Energy offers a wide range of synchronous condenser solutions that can be seamlessly integrated with large gas turbines and steam turbines.
