• Improved reliability owing to N+1 parallel operation
  
• Compensating unbalanced current owing to parallel operation
  
• Mimic display panel on the front helps a user check the system

Applications

• Nuclear power-, thermal power- or hydroelectric power plant
  
• Direct/indirect exciter for thermal power plants
  
• Workplace using a large capacity rectifier requiring high reliability

Details

• PCR(Phase Control Rectifier) for a power plant, an automatic voltage regulator adjusting the output voltage of a synchronous generator controls DC current on field winding, adjusting the voltage of a generator.
  
• PCR consists of voltage control unit and rectification unit.
  
• Control unit collects and analyzes signals from a generator/exciter to control a facility, displays the current status using panel PC or PC and records data.
  
• Rectification unit that receives control signal from the controller and supplies DC current, which is on a generator's field, controls DC current that is on a field winding of a generator, adjusting the voltage of a generator.
  
• It ensures the reliability as it is designed with N+1 mechanism for normal operation even though one of rectifiers is broken.
  
• It solves unbalanced current problem, which occurs when multiple rectifiers are operated at the same time.
  
• Mimic display unit is attached on each rectifier for an operator to check the current status and any failure
  
• This product is delivered to all of the domestic power plants and generation fields as its reliability and stability has been well reputed.
