Synchronous Condenser Systems

Today’s Environment For most utilities ensuring grid reliability, efficiency, and security is a primary concern. As the grid evolves and load profiles change, stresses are being put onto transmission and distribution networks, making the need for voltage support and grid management much more challenging. Globally, utilities are facing many new grid challenges and conditions including: GE offers transmission utilities a simple and reliable solution to address reactive compensation and voltage support requirements. Our newly re-designed motor based Synchronous Condensers are custom designed to...

Benefits of GE's Synchronous Condensers Short-term Overload Capability Minimal Harmonic Generation The GE Synchronous Condenser has a large current overload capability, which can provide beneficial system support during emergencies or short term contingencies. As seen below, a GE Synchronous Condenser can provide more than two times its rating for up to 10 seconds. The machine’s significant overload capability can be accounted for in choosing the size of the machine required. The Synchronous Condenser is not a source of harmonics and can even absorb harmonic currents. The lack of harmonics help...

Customer Success Customer name: Vermont Electric Company (VELCO) Location: Granite Substation, Vermont, USA Application/Challenge: As part of the Northwest Vermont Reliability Project a number of upgrades were investigated to provide for the reactive power needs at the Granite substation. Simulations indicated that the power system is very near a point of voltage instability. In the case of an outage of the Vermont Yankee – Coolidge 345kV line, a continuous reactive power control device is critical to prevent voltage collapse.
