9-1:
DSTAR Distribution e-Handbook
Distribution engineers and
technicians frequently use one or more "paper" handbooks to find vital
engineering information or refer to tables in these handbooks to obtain simple
calculated values. The goal of the DSTAR Data
e-Handbook is to create a dynamic electronic document that consists of
information commonly used by the DSTAR membership. Covering a variety
of distribution engineering topics, the DSTAR e-Handbook is intended to be an
authoritative source of information. The material included in the e-Handbook
has been obtained from existing distribution handbooks, manufacturer
information, standards documents, results from DSTAR software programs, and
surveys of the DSTAR membership.
9- 2:
Cable Pulling Assistant (CPA) Software
Enhancements
The Cable Pulling Assistant
(CPA) software is used to quickly calculate cable pulling tensions and
sidewall pressures for a given layout. It allows easy comparison of pulls in
either direction. CPA also calculates probability of cable jamb, conduit
fill, and conduit clearances. This software enhancement provides the user and
administrator with additional flexibility in entering data and aligns the
calculation algorithm with AEIC CG G5-90.
9-3:
Guy Tension Analyzer (GTA) Software Enhancements 1
GTA calculate tensions on guy
wires and guy anchors for dead-end and angle distribution poles. This project
updates GTA to calculate minimum pole class based upon the vertical loadings
applied by user specified loading conditions and guying. Additionally, the
pole loading and class are calculated for an unguyed pole situation.
9-4: Guy
Tension Analyzer (GTA) Software Enhancements 2
The Guy Tension Analyzer
software tool is used to calculate tensions on guy wires and guy anchors for
dead-end and angle distribution poles. The tool can handle three types
of guy wire configurations: 1.) standard (guys connected directly to anchors
from a line pole), 2.) span guy, and 3.) sidewalk guy. In the standard and
span guy configurations, up to ten lines (ten lines in each direction for
angle poles) can be accommodated, together with up to ten tap lines
terminating at an arbitrary angle with respect to the main line (feature not
supported with sidewalk configuration), as well as five guy wires and
anchors. The tool provides complete flexibility to connect any guy to any
anchor. This software enhancement focuses on updating the GTA calculation
algorithm to include resultant guying.
9-5: Economic Overhead
Conductor Sofware (EOCS)
Proposed is a project to
develop a software program for determining economic overhead conductor
selection curves to be used by utility engineers and technicians for selecting
the lowest life cycle cost conductor installation based on existing or
anticipated present load (equivalent peak kVA) and expected load growth
(%/year). The developed program will be a Windows-based software tool which
will allow the utilities to prepare lowest life cycle economic conductor
selection charts considering installation costs, loss costs, and change out
costs.
9-6:
Secondary Electrical Design Software (SEDS) Enhancement
The
Secondary Electrical Design Software (SEDS), developed during Program 7, has
been successfully used by the DSTAR membership to perform electrical
calculations, such as voltage drop and flicker, for multi-tiered, single-phase
secondary systems. SEDS employs a drag and drop-style user interface that is
very simple to use and affords users tremendous flexibility. There are some
situations where unbalanced, three-phase loads are connected to the secondary
system and need to be analyzed. This new project is intended to serve this
need.
