Tension transmitter HVDC PLUS

A new approach for new challenges Transmission systems need to live up to new challenges in the wake of decarbonization, decentralization, and digitalization: A growing number of large-scale offshore wind farms needs to be connected to the grids, strained AC grids must be stabilized to ensure reliable operation, energy-hungry megacities require low-loss power supply solutions. This is where Siemens’ outstandingly compact HVDC PLUS technology comes into its own. Based on trendsetting modular multilevel voltage-sourced converters, it is blazing the trail for modern trends in HVDC transmission by making it possible to combine the advantages of HVDC transmission with extra benefits such as AC voltage control, black start capability, and other functions that improve the performance and security of any transmission system. Improve grid performance with flexible HVDC technology Transmission system operators need to handle increasingly complex grids and meet new demands. Space-saving, innovative HVDC PLUS systems help live up to challenges such as the reliable power supply of metropolitan areas, the improvement of grid stability, and grid access for offshore wind farms. The smart answer to new challenges in complex transmission systems •Full four-quadrant operation for independent, flexible active and reactive power control •Flexible AC voltage control to support weak AC networks •Robustness against AC network disturbances: Can be operated under asymmetrical AC network voltage conditions and can help compensate unbalanced loads •Ability to contribute to short circuit current and to black-start shut-down networks
