The DC System Analysis Module

The DC System Analysis includes: Battery Sizing, DC Load Flow, DC Short Circuit (ANSI), and DC Short Circuit (IEC).

Comply with Industry Standards:

  • Battery Sizing - IEEE standard 485 for sizing Lead-Acid batteries and IEEE standard 1115-2000 for sizing Nickel-Cadmium batteries, determines the size of batteries to supply the worse case DC duty cycle loads and AC emergency loads.
  • DC Load Flow - Calculates power, current and voltage drop profiles. Represents constant kW, I, and Z, load types and evaluates all loading conditions for duty cycle loads and AC emergency loads.
  • DC Short Circuit - ANSI standard 399 and 946, calculates the initial rate of rise and peak fault current.
  • DC Short Circuit - IEC standard 61660, calculates the peak fault current, time constants, time to peak, and steady state conditions.

Benefits:

  • 1. Save time with intuitive scenario manager interface.
  • 2. Communicate designs effectively with graphical and text base results.
  • 3. Improve decisions by quickly comparing resulting curves from different scenarios.
  • 4. Increase productivity by modeling both DC and AC systems in a single project.
  • 5. Reduce mistakes by evaluating all loading conditions and duty cycle loads.
  • 6. Battery Sizing and Load Flow automatically calculates AC emergency loads and their impact on the DC system to help you design safer and more reliable systems.
