DC System Analysis

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:

Save time with intuitive scenario manager interface.
Communicate designs effectively with graphical and text base results.
Improve decisions by quickly comparing resulting curves from different scenarios.
Increase productivity by modeling both DC and AC systems in a single project.
Reduce mistakes by evaluating all loading conditions and duty cycle loads.
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.
