Casco Systems LLC offers experience automating power transmission and
distribution projects including high voltage substations and capacitor banks.
A sample of typical projects is noted below.
34.5kV Substation Integration (2005)
Developed
software for an integrated substation utilizing Schweitzer Engineering Labs
(SEL) 2032 data concentrator, 2516 I/O modules, and various relays. All
station analog and digital status data was collected and consolidated by the
data concentrator. Collected data included time stamped breaker
Momentary Change Detection and Distance to Fault information.
Alarm data was provided to a local operator interface for annunciation while
supervisory data was made available to a GE XA/21™
EMS. The EMS communicated with the local 2032 using DNP 3.0 protocol.
This designed eliminated the typical Remote Terminal Unit (RTU) or local
Programmable Logic Controller (PLC), significantly streamlining the design and
reducing cost.
115 kV Cap
Bank Automation & Control System (2005)
Program and assist with the commissioning of a GE Fanuc 90-30 PLC based Capacitor Bank
control system at a 115 kV substation in New Hampshire.
System provided automatic control of two 115kV capacitor banks and
circuit switchers; high voltage backup tripping of both cap banks; and digital interface
to Harris D20 RTU.
Al Mussaib, Iraq
Substation Automation (2004)
Developed CIMPLICITY HMI
SCADA system for a 400 kV substation being constructed at the largest
generating station in Iraq. The Substation Integration System provides local
monitoring and breaker control functions for five breaker and a half bays,
including GSU Transformers T1-T5; Breakers 52-1 thru 52-15; Transmission Lines
L1-L4 and Bus 1 & 2.
The system is comprised of
GE Fanuc’s CIMPLICITY HMI Plant Edition Graphical User Interface and
Schweitzer SEL-2030 Data Concentrators. The HMI software acts as a ModBus
Serial RTU Master and retrieves station status information from intelligent
electronic devices via three SEL-2030 data concentrators. The SEL-2030’s poll
the station’s protective relays and meters for target, analog, status, and
metering data. This data is then read from the 2030’s by the HMI system and
displayed in numerical and graphical formats.
This system was developed
and factory tested in under 2 months to meet an aggressive shipping schedule.
Following a rapid software development process the system was shop tested
concurrently with final control room wiring.
Power System Transfer
Switching Control System Programming (2002)
Designed & configured
a PanelMate PC-based operator interface; programmed AB SLC 500 to AB
PowerMonitoring II Remote I/O Block logic; and programmed logic for SLC to SLC
Ethernet communications scheme as part of a team which designed, developed,
and installed an automated switching and monitoring system for a 11.5kV
university campus power system.
34.5 kV Line
Section PLC/SCADA (2002)
Programmed Series
90-30 PLC, PanelMate OIT, and SCADA communication interface to add control and
alarm functions for Sections 25 & 77, as well as related breakers.
34.5kV Capacitor Bank
Addition (2001)
Designed electrical control system and programmed associated GE Fanuc 90-30
PLC to control four capacitor banks.
System provided automatic control of four 34.5 kV capacitor banks and
circuit switchers; high voltage tripping of cap banks; and remote SCADA
interface.
345 kV Substation
Reclosing and Annunciation System (2000)
Planned, programmed,
and commissioned a GE Fanuc 90-30 PLC based automatic reclosing system for a
nine breaker substation bus; implemented PLC based SCADA interface; designed
station annunciator logic including a local PanelMate operator interface.
115/345 kV Cap
Bank Automation & Control Systems (2000/1)
Programmed and
assisted with the commissioning of a GE Fanuc 90-30 PLC based Capacitor Bank
control system at two 115/345 kV substations.
Each system provided automatic control of two 115kV capacitor banks and
circuit switchers; high voltage backup tripping of both cap banks; and SCADA
interface.
Capacitor Bank
Automation and Control System
(2000/1)
Similar to the
projects listed above, the Mason project also involved the implementation of a
90-30 PLC based intelligent SCADA interface which allowed the PLC to emulate a
Remote Terminal Unit.
115/345 kV
Capacitor Bank Automation and Control System (2000/1)
System provided
automatic control of three capacitor banks and circuit switchers; high voltage
backup tripping of both cap banks; and SCADA interface.
Energy Monitoring
System
Created novel energy
monitoring system to track and report energy savings from a variety of energy
conservation projects. System
collected energy usage data, calculated performance data, formatted reports,
and reported energy savings data to a central database system.
