PGE’s power system field teams provide a comprehensive suite of engineering and technician services with a focus on “Safety Around The Clock.” Our power system field teams are available for specific projects, ongoing support projects, or staff augmentation projects. Our skilled and knowledgeable staff are proven leaders in supporting the unique standards and peak performance requirements of our client’s networks. PGE’s world-class engineering and test personnel are fully trained on various test equipment, software applications and platforms including Omicron, Doble, Pro-Test and RTS. The PGE power system field teams are also equipped to conduct studies and analyses utilizing NERC-MOD and TPL standards.
Relay technician staff augmentation performing maintenance, construction, troubleshooting and emergency operations.
Installed new conduit, control cables and panels for redundancy protection to a 230/138 kV autotransformer. PGE provided total construction management and a team of test engineers. This very complex project was completed with only 3 weeks of preparation.
In supporting a Smart Grid initiative, PGE installed battery monitoring systems in over 185 substations, requiring only 8 weeks.
Upgraded two 230/138 kV Autotransformers.
Replaced primary generator protection of three combustion turbine generators with SEL-300Gs.
Performed troubleshooting of an improperly operating sudden pressure relay, including problem duplication and Root-Cause-Analyses studies utilizing relay manufacturer partnership.
Performed end-to-end line protection testing on three 230 kV transmission lines using Doble F6150 with Satellite Synchronization. Also utilized an ASPEN file to create specific line fault simulations, and performed testing in POTT and DCB line protection schemes.
As the primary contractor, PGE constructed, tested and commissioned a FERC mandated redundancy project of four 138 kV lines, three 230/138 kV Autotransformers, two 138 kV and two 230 kV Busses. Project also replaced 18 Coupling Capacitor Voltage Transformers, installed 8k-ft of conduit, 20k-ft of control cable, and added a second DC system (battery bank, battery charger and DC load center).
