High speed bypass switch for high voltage DC systems

Request Number N465215
Need details
Description

Development and / or supply of a high speed bypass switch for high voltage DC applications.

.

The switch is part of every level in High-Voltage Direct Current (HVDC) and Static VAR compensator (SVC) multilevel converters.

 

 

 

 

 

 

 

 

 

Background

Siemens Energy Management is a partner to develop and / or supply HVDC and SVC multilevel converters. 

.

In HVDC and SVC converters many power modules are connected in series. To ensure a highly reliable and uninterrupted converter operation a device to bypass a failed power module is needed. The voltage level of every power module is given by available Insulated-Gate Bipolar Transistors (IGBTs). If a power module should fail a fast bypass switch has to be closed. The bypass switch remains closed after a single ignition.

.

Key Success Criteria

Siemens Energy Management is seeking:

  • New approaches for high speed, high voltage bypass switching
  • That have the potential to meet the specifications of the current bypass switches used in Siemens systems
  • Can be developed in approximately 12 months

The specifications of the current bypass switch we use are:                                              

  • Bypass switch for voltage class between 3.3 kV and 6.5 kV          
  • Closing time equal to, or lower than, 10 ms
  • Current higher than 1500 Amps

 

  • Better performance than above, if possible, is welcome 

 

 

 

 

 

 

 

 

Possible Approaches

Siemens is open to all possible solutions for example, but not limited to:

  • Electrical
  • Mechanical
  • Semi-conductor
  • Vacuum tube
  • Pre-tensioned springs or equivalent

 

  • Other solutions are most welcome.

 

Approaches not of interest

Siemens is open to all possible solutions.
