v5.0 [Dec 26, 2012]
1.New Unbalanced Power Flow Program
A Load Flow analysis is used t--evaluate the running steady-state condition of a system, under different load, supply and configuration conditions. Power Analytics Unbalanced load Flow model easily identifies unbalanced system characteristics.
Large amounts of unbalanced current can cause negative sequence and ground relays t--operate. There are many problems that result from "to--much" unbalance. If the load is balanced there will be n--current flowing in the neutral. For that reason a neutral wire is sometimes not connected t--a balanced three phase load. An unbalanced load will cause neutral current t--flow, if a neutral is connected. Due t--unbalanced load ,some current will flow through the neutral wire; hence due t--I2R losses, voltage drop will occur in neutral - s--the voltage regulation will decrease.
2.New Short Circuit Program Features
--New Bus Short Circuit Evaluation feature (PDE). Seamlessly provides instant comparison of short circuit results and bus ratings.
--New Impedance Tolerance feature for generators, transformers and feeders. Enables easy setup of multiple maximum and minimum fault calculations
3.Improved photovoltaic short circuit model. Introduces advanced inverter options for accurate calculations.
--Additional flexible annotations. Provides options t--simultaneously display several IEC-61363 short circuit components on the one line diagram.
--New Case Study feature that enables t--save customized short circuit options.
4.Extended computation of thermal currents t--LG, LL, and LLG faults.
--Scenario-Dependent DC short circuit temperatures. Fully integrated capability t--simulate effects of multiple temperature variations on DC system faults.
--New VFD Regenerative Mode. Augments IEC-61363 motor short circuit model with a new user defined percent rating of let-through current.
5.New Functions in PDC Program
--New single phase PDC. Coordination curves can now be entered directly int--single-phase equipment.
--New Multi-Segment Relay capability. Enables use of tw--instantaneous segments.
--New User-Defined Short Circuit Arrows. User can specify short circuit level independently of the components used in the study.
6.New Text Editor
--New user friendly spreadsheet implementation. Enables users t--directly copy and paste 3-phase, DC, and single phase data from text editor t--Microsoft Excel and vice versa.
7.Enhanced Cable Ampacity Program
--New function t--vary percentage of current returning through sheath, shield, concentric neutral or skid wire.
--Improved GUI with Spreadsheet implementation; enables quicker edits and changes in cable installation cases.
8.Innovative Harmonic Program Features
--Special user-defined harmonic impedances. User can define impedances for selected elements in the network. This feature is being used for harmonic analysis of offshore platform fed by long subsea cables.
--New Global Copy and Paste function. Enables pasting of all properties of one component (e.g. feeder) t--several other components at the same time; single paste over multiple components.
--Several enhancements t--DesignBase licensing:
--Upgrade t--Flexnet version 11.10.1.0
--Simplified license server interface
--Added more user friendly warning messages t--help resolve network connectivity issues.
--New Text Report Viewer program. Enables quicker edit and formatting capabilities similar t--Microsoft Word.
--Enhanced Digitizer t--automatically work within the Fuse library program
--Additional key tools t--facilitate shipbuilding design:
--New Branch Voltage Drop report in Power flow
--New single phase load analysis option
--New Interactive Error Checking Report. Offers a user friendly global view of model discrepancies and missing data. Each error can be resolved by simply clicking on its log entry in the report.
--PDC library enhanced with hundreds of new devices
9.New Help files format
