PSS®E 34.0 Highlights

• Integrated Node-Breaker Support• Node-Breaker topology support in engine• Automatic substation topology generation• Novel approach for linking Bus-Branch and Node-Breaker worlds• Node-Breaker contingency analysis

• Updated study file management system• Improved power flow models• Solution parameters saved in SAV, RAW and SEQ• Support for branch names• 12 Customizable ratings groups• Results spreadsheets• Geomagnetic Induced Current (GIC) improvements• New dynamics models• Many user interface, diagram, settings and plotter improvements

May 2015



Automatic Substation Building

• Choose from several common substation configurations (breaker and a half, ring bus, etc)

• Easily add multiple buses at different voltage levels

• 90% of the work is done for you. Terminals can easily be moved after the initial layout is generated

May 2015



Linked Bus-Branch and Node-Breaker Diagrams

• Visual indication and clickable link for substation diagram in bus-branch view• Easily drill down to substation detail from the bus-branch model• Customized substation diagrams will automatically be loaded if available, or

diagrams will be create dynamically as needed.

May 2015



Example Node-breaker Contingencies

fault line from bus 101 to bus 102 ckt 1 / open line with

brkrs

isolate branch from bus 201 to bus 202 ckt 2 / open line with

brkrs

fault bus 3005 / clear bus with

brkrs

disconnect swd sub 4 from node 5 to node 2 / open brkr or switch

close swd sub 2 from node 1 to node 7 / close brkr or

switch

isolate swd sub 1 from node 3 to node 8 / isolate brkr with

brkrs

contingency "stuck_brkr_example" fault line from bus 101 to bus 102 ckt 1 / open line with brkrs isolate swd sub 1 from node 1 to node 2 / stuck brkr at remote termend

Notes: PSS®E 34.1 will have expanded NB contingency support including automatic NB contingency generation

May 2015



Improved Study File Management System

• Formally known as Scenarios• Streamlined operation• New Study Explorer view for simple file management

May 2015



Power Flow Modeling Additions

• Distributed generation mode and parameters in load model• In-feed control mode for machines

May 2015



Solution Parameters in RAW and SEQ

• Power flow and short circuit solution parameters are stored in the SAV, RAW and SEQ files

• The exact solutions can be replicated when re-opening or transferring case data

May 2015



Branch Names and 12 Ratings Sets

• Branch names are supported

• Must be unique (future PSS®E versions will use as key fields for APIs, contingency definitions, reports, etc)

• There are now 12 ratings sets with customizable names and descriptions

• Use for various conditions, seasons, time limits, or anything you want.

• Select from these 12 ratings for single line diagram loading results, ACCC violations, etc

May 2015



Results Spreadsheets

• Spreadsheets for results (and totals data) for network elements and aggregations

• Examples: • Branch spreadsheet with all branch flows and losses• Fixed shunts spreadsheet with actual MVAR• Area spreadsheet with total load, losses and interchange

May 2015



Dynamics Models

• New IEEE 421.5 ModelsST1C, ST5C, ST7C, AC1C, AC2C, AC3C, AC4C, AC5C, AC6C, DC1C, DC2C, AC6A

• New Governor Model (Pratt amp; Whitney Turboden turbine-governor)PWTBD1

• New Machine Protection Model (V/Hz Generator Relay Model)VPERHZU1

• The following user models have been converted to standard modelsDCTC1 is now DCTC1TLOEXR1 is now LOEXR1T
