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 2000, XP, Vista and Windows 7.
- Models the distribution network in the phase domain (and not in the sequence domain) for short-circuit, locked-rotor and voltage-drop studies.
- Short-circuit and locked-rotor studies can use results of a voltage-drop study as initial condition.
- Handles radial or network systems. Each network can have multiple feeders. Each feeder can be fed by any number of substation buses and generators.
- Has the ability to calculate feeder reliability.
- Has built-in harmonic analysis engine for frequency scan and harmonic load flow solution.
- Has built-in arc flash calculator.
- Models balanced 2-winding transformers, as well as transformers that are made up of one, two or three single-phase banks with different kVA ratings and impedances.
- Models 3-winding transformers without fictitious buses.
- Has a comprehensive set of distribution system components, including 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.
- Models distributed loads 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.
- Has the ability to allocate loads in a batch mode using billing data or other sources.
- Models spot loads and section loads as a mixture of constant power, constant impedance and constant current components in voltage drop studies.
- Models induction generators and motors, both 3-phase and single-phase.
- Models synchronous machines and synchronous condensers. Each machine can be controlled to hold constant voltage or power in a voltage drop study.
- Has models for overcurrent relays, fuses, reclosers and sectionalizers. The program comes with curves for about 3000 relay, fuse and recloser types. The relay library is user modifiable.
- Plots transformer damage curve and inrush curves automatically.
- Has models for most distance relays. The distance-relay library is user modifiable.
- 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.
- 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 and displays simultaneously the fault currents for all the buses on the one-line.
- 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.
- Can output vector-graphics file that can be imported into AutoCad and similar software.
- Has capacitor placement algorithm for loss reduction.
- Has automatic coordination checking algorithms for any mix of fuses, reclosers and relays.
- Comes with data conversion program for MutiSpeak data files.
- Proven in utilities worldwide.
