Supervisory Control & Data Acquisition Projects
Empire Electric Association, Cortez, Colorado, 2002-present
Integration of SCADA hardware including devices from several manufacturers. The SCADA Master Station was supplied by Advanced Control Systems; the remote devices are Harris D20 controls. Interfaced several legacy devices and protocols. The end product is a complete SCADA system for Empire Electric that has integrated the Harris 5500, DNP and Harris Proprietary protocols to provide control, status and metering.
Reedy Creek Energy Services, Lake Buena Vista, Florida, 2003-present
Integration of SCADA at Reedy Creek includes interfacing to several different controls and protective relays. EEC specifies SCADA points and performs the DNP mapping of the SEL – 2032 to the following Schweitzer relays; SEL – 279H2, 300G, 321, 351, 387, 487B, and 551. EEC also integrates the following relays and meters into the master station by serial MODBUS: Beckwith M3425A generator protection relay and 2001C LTC control, Areva P544 line differential relay, and Phasor power meter.
Roseville Energy Park and Fiddyment Substation
City of Roseville, California, 2004-2005
EEC performed schematic design, wiring and configuration of Harris D20s for Fiddyment Substation and Roseville Energy Park. All configuration of monitoring analog and digital points was performed at the 60kV level and each site had over 500 points to configure.
Complete SCADA System
City of Fort Morgan, Colorado, 2003-2005
Design, specification, bidding process, bid evaluation, and assistance in final selection for the complete SCADA system for the City’s five substations. The final system is a C3-Ilex system that includes all of the RTU’s and the Master station. Engineering included HMI development for all Master station screens, DNP mapping of the SEL – 2032 to SEL 387, 551 and 587 relays, and integration of SATEC PM130 power meters, Cooper Form 5 reclosers and ABB PCD2000 reclosers. EEC mapped all of the information into the master station for the first substation and then instructed City personnel on implementation for the additional substations. The 900MHz radio was specified by EEC and installed by a contractor.
SCADA System Implementation
Poudre Valley Rural Electric Association, Fort Collins, Colorado, 2000
Implemented SCADA in all PVREA substations. Performed SCADA conditioning (equipment interface and wiring design) for the Harris D20 controls and performed interface testing and commissioning of the system.
Campus Metering System
National Renewable Energy Laboratory, Golden, Colorado, 1999-2001:
Designed, specified, bid, and evaluated a new SCADA system for two testing and research campuses for NREL. Provided SCADA integration for all of the devices. The system includes protective relays, power quality meters and Ethernet gateways for integration into the existing NREL network as well as local HMI displays for equipment. The system uses GE Multilin equipment communicating via TCP/IP, EEC created all of the Ethernet maps for the controls. Local HMI’s were created with Wonderware and included meter totalizing and cost structure databases as well as event records.
SCADA System Implementation
Highline Electric Association, Holyoke, Colorado, and Y-W Electric Association, Akron, Colorado, 1999
Integrated the SCADA equipment in all of the substations in the Highline and Y-W service territories. The substations were prepared by implementing a cost effective approach using existing drawings, field work, construction drawings and photographs to provide status, metering and control installations. Cannon Technologies interface capacitors were used to connect to the distribution system and 900MHz radio was used to provide all of the data to the central control centers of the two REA’s.
SCADA System
City of Benkelman, Nebraska, 1997-1999:
Designed, specified, bid, and evaluated a new SCADA system. The new system uses an ABB controller to remotely interface to pad-mounted switches and protective relays at the power plant and also a remote substation. The protective relays provide status, metering, and breaker/recloser controls. A separate PLC at the pad-mounted switches provides status and control and is interfaced to the power plant with a direct fiber optic link. The substation interface to the power plant is via hard wire.
