I have an update of 7.0.2.4 to 7.0.4.4 maybe it is not the latest but the software key will be disabled after the update. The key.gen no longer works.
Description DAPPER Studies DAPPER is an integrated set of modules for Three-Phase Power System Design and Analysis including rigorous load flow and voltage drop calculations, impact motor starting, traditional fault analysis, demand and design load analysis, feeder, raceway and transformer sizing, and panel, MCC, and switchboard schedule specification. Discography Avicii more. Benefits: • 1. Generate better designs by comparing alternatives quickly. Improve accuracy with DAPPER’s rigorous solution methods. Save time by sharing a common project database and interface. Improve consistency with standard design libraries.
Design safer systems by comparing calculations with short circuit and continuous ratings. Communicate designs effectively with presentation quality graphics, reports, and equipment schedules. LOAD FLOW/VOLTAGE DROP: With DAPPER, users can calculate the voltage drop on each feeder and transformer branch, voltage on each bus, projected power flow, and losses in the power system. This program may be used for conventional voltage drop analysis, loss analysis, power factor studies, capacitor placement, long-line charging effects, impact loading for motor starting studies, generator sizing, and for cogeneration analysis. With DAPPER, a single load flow program models loop and radial power systems.
Features: • Models radial, loop, and multiple independent systems. • Models utility and generator equivalent impedance calculated from short circuit duty.
• Models up to 50 utilities/swing bus generators. • Models up to 400 regulated and unregulated co-generators. • User definable per unit driving voltage at each utility and swing bus generator.
• Models transformer primary and secondary taps and off nominal rated voltages. • Full transmission line modeling with built in line parameter calculators. • Models any combination of motor and non-motor loads with global and/or local load factors. • Models any combination of constant kVA, constant impedance and constant current loads. • Reports bus voltage, voltage angle, and voltage drop at each bus. • Reports branch voltage drop, power flow in kW, kVAR, kVA, Amps and power factor.
• Reports branch loss in kW, kVAR, kVA, and total system losses. • User definable report criteria for bus and branch voltage drops. • Percentage voltage drops based on system voltage per ANSI standards. • Double precision calculations improve solution accuracy. • Rapid solution convergence. • Suitable for impact motor starting, capacitor placement and power factor studies. • Load flow results validated to match with benchmark calculations and IEEE examples.
COMPREHENSIVE FAULT ANALYSIS: The DAPPER Comprehensive Fault Analysis program provides a network solution of three-phase, single-line to ground, line-to line, and double line to ground fault currents; RMS momentary fault currents; asymmetrical fault duties at three, five, and eight cycles; the positive, negative, and zero sequence impedance values between each fault location, and contributions from utilities, generators, and motors. At each fault location, the direction, X/R, and magnitude of fault currents are reported, thus providing a clear view of the conditions that exist during the fault. Features: • Symmetrical and Asymmetrical values reported at 1/2, 3, 5, and 8 cycles. • Asymmetrical values reported at user selected fault time.
