34.5kV Substation Integration
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/21RTU and 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
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.
Power System Transfer Switching Control System Programming
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
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
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
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
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
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
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.
Casco Systems LLC offers extensive experience with integration and automating of power transmission and distribution projects including high voltage bulk transmission substations, distribution substations, power distribution, Synchronous condensers, DVAR, and capacitor banks.
