Power System Studies:

High voltage power transmission technology is constantly evolving, making informed decisions can be difficult without expert advice. Our power system experts will ensure the decisions made are informed by the most recent available data and analysis techniques, as well as recent trends and industry practices. 

We have carried out a wide range of studies on many of the world’s major power transmission networks, both HVDC and HVAC.

The types of studies we perform include:

  • Feasibility studies

  • System planning studies

  • Operational planning studies

  • Solar, onshore and offshore wind farm Interconnection Studies

  • Renewable energy integration studies (e.g. wind, solar, storage)

  • Single line design and Equipment specification

  • System restoration studies

  • Power flow, short circuit and dynamic studies

  • Transient stability analysis

  • Electromagnetic transient studies, such as insulation coordination, Transient Recovery Voltage (TRV) and resonance studies, and control interaction studies

  • Subsynchronous resonance studies

  • Harmonic analysis

  • Model validation and custom model development

  • AC and DC filter design (performance and rating calculations)

  • Protection setting and coordination studies

  • HVDC electrode design and interference effects

  • Electrical and magnetic effects of DC and AC transmission lines

  • Arc Flash Studies

  • Geomagnetic Disturbance (GMD) Analysis

  • NERC protection compliance

  • Power Line Carrier Communication (PLCC) studies

We are well-versed in a variety of standard and industry-leading specialized tools, including: PSS/E, PSCAD, EMTP, ASPEN, CAPE and ETAP, as well as fully validated specialized software tools we’ve developed in-house.

Whatever your project needs, scale or challenges, you can trust OHM Engineers to optimize the accuracy of your system or equipment, perform the analysis, and work with you to achieve your goals efficiently.
