Increasingly decentralized energy systems and the associated uncontrolled power flows pose new challenges for the existing, mature grid infrastructure. Thermal overloads in the lines and a growing number of cases in which frequency and voltage come critically close to acceptable range limits, or even exceed them, threaten grid stability and the transmission infrastructure, and often require costly redispatch intervention to deal with current and voltage factors. Compared to traditional power flow controllers, UPFC PLUS® controls power flow in just milliseconds. The Unified Power Flow Controller UPFC PLUS® thus stabilizes the AC grid even when critical situations develop suddenly (Grid Code N-1). That means UPFC PLUS® lets you get the most from your existing grid capacity while maintaining maximum protection, reducing the risk of power failures, and minimizing redispatch costs.
Go on a journey of discovery in our digital showroom and get to know the Unified Power Flow Controller UPFC PLUS® from a new perspective.
An unified power flow controller (UPFC) from Siemens Energy redirects current within milliseconds. Your solution to meet n-1 standards and to secure power supply even in hazardous events.
With a response time of just milliseconds, UPFC PLUS® is significantly faster than a phase shifter so you can intervene much faster in critical situations.
Unlike a phase shifter, UPFC PLUS® is not only able to control power flow but also enables dynamic reactive power compensation and voltage control and it can also compensate for disruptive factors like vibration.
