Exponential Engineering, in partnership with Electrical Reliability Services, is in an ongoing relationship to expand Xcel Energy Substation capacity. EEC provides the SCADA configuration upgrades including programming and commissioning of the status and control points.
EEC provided configuration and installation support to Xcel Energy for the Sky Ranch SCADA Upgrade using Novatech’s OrionLX RTU. EEC worked with contractors to install the equipment then modified the hardware configuration, the RTU database and the HMI screens to match the new design. EEC then tested the full functionality of the SCADA system, including the programming of the ATO …
230kV Switching Station – the switching station is configured as breaker and a half bus containing six 230kV, 2,000A breakers and provisions for six future breakers, with four transmission line terminals and four additional future transmission line terminals. 230kV Transmission Line design consisted of 4 double circuit lines on self-supporting steel poles for the substation exits. The switching station and …
Design of generator, transformer, bus and 5kV protection for three 206MVA gas turbine generators (Units 2, 3, 4) at Fort Saint Vrain Station in North Central Colorado; design included one-lines, AC three-lines, DC schematics and relay settings; provided commissioning support to site during outage and calculations for 100% stator ground fault protection. Primary and Backup relaying for generators and generator …
For each project, we were asked to be involved as a third party to review relay settings proposed by First Energy’s design engineering firm. We provided relay settings calculations in Mathcad, which included our recommended changes.
Performed a GSU sizing analysis for a new combined cycle natural gas power plant being designed for Xcel Energy at Cherokee Station. Analysis involved specifying size, impedance and cooling requirements for the three new generator step-up transformers.
