ASPEN DistriView
DistriView: An integrated analysis tool for distribution engineers
ASPEN DistriView™ is an integrated suite of voltage drop, short circuit, relay coordination, and harmonics and reliability calculation software for utility distribution systems. DistriView is designed for networks that has a mixture of 3-phase, 2-phase and single-phase network components, including unbalanced loads and shunts. The user interface is very similar to that of ASPEN OneLiner, with split windows, floating menus and a data browser. Some highlights of DistriView are these:
Native Microsoft Windows program.
Easy-to-use interactive graphics interface under Windows 7, 8 and 10.
Models the distribution network in the phase domain (and not in the sequence domain) for short-circuit, locked-rotor and voltage-drop (load-flow) studies.
Handles radial or network systems. Each network can have multiple feeders. Each feeder can be fed by any number of substation buses.
Simulate short circuits: bus faults, close-in faults, line-end faults and intermediate faults.
Simulates lock-rotor condition for single- and 3-phase induction machines, with a variety of starting methods.
Simulates distribution transformer faults and reports on fault current on the low side.
Simulates voltage drop with a true 3-phase load flow algorithm.
Short-circuit and locked-rotor studies can use a voltage-drop solution as initial condition.
Has advanced analysis tools: stepped-event analysis, voltage sag analysis, arc-flash calculation and more.
Has built-in harmonic analysis engine for frequency scan and harmonic load-flow solution.
Has the ability to calculate feeder reliability.
Has built-in calculator for overhead-lines and cable impedances. Has library of large number of commonly used conductors, pole constructions and underground cable circuits.
Has a fault locator command that accept fault records from COMTRADE files, PDQ files and SEL event files with EVE or CEV extension.
Has arc flash hazard calculator based on IEEE 1584-2011 and -2018 standards.
2-winding transformers: Balanced 3-phase, as well as transformers that are made up of one, two or three single-phase banks with different kVA ratings and impedances.
3-winding transformers without fictitious buses.
2- and 3-way switches, circuit breakers, voltage regulators and boosters, switchable capacitors, grounding banks, and single-, 2-phase and 3-phase lines and cables.
Spot loads and section loads modeled as a mixture of constant power, constant impedance and constant current components in voltage drop studies.
Distributed loads: modeled as ‘section loads’ on lines and cables. The total source load can be allocated to section loads using REA, kWh and kVA methods, as well as using line length.
Synchronous machines and synchronous condensers: Each machine can be controlled to hold constant voltage or constant power in a voltage-drop study.
Induction generators and motors: both 3-phase and single-phase.
Inverter-interfaced generators: for modeling solar, wind type-4 and other generators.
Type-3 wind generators, also known as doubly-fed induction generators.
Advanced relay modeling:
Overcurrent relays, fuses, reclosers, sectionalizers and compounded overcurrent devices: The program comes with curves for about 3000 relay, fuse and recloser types. The relay library is user modifiable.
Distance relays: Has generic mho and quadrilateral characteristics, as well as manufacturer-specific models that mimics the fault-detection and tripping logic of commercial relays from ABB, GE, SEL, Areva, Siemens, and others.
Has the ability to import distance-relay setting parameters from files generated by GE, SEL and other relay manufacturers.
Has automatic coordination checking algorithms for any mix of fuses, reclosers and relays.
Has the ability to allocate loads in a batch mode using billing data or other sources.
Plots transformer damage curve and inrush curves automatically.
Choice of IEC or American transformer symbols, 50 or 60 Hz, English or metric units.
Displays results of voltage-drop, short-circuit and locked-rotor simulations graphically with color visualization of over- and under-voltage areas.
Can output vector-graphics file that can be imported into other software.
Has capacitor placement algorithm for loss reduction.
Can read ASPEN OneLiner data files.
Comes with data conversion program for ArcFM and PTI ADEPT (PSS/U) data files.
