Technical Abilities
Distributed Generation Connection Impact Assessments
A Connection Impact Assessment is a detailed assessment of a project’s impact on the grid. It is especially important in the deployment of the distributed energy resources (DERs) that are bringing unique benefits that central-station power plants and long-distance transmission and distribution alone did not achieve.
Our experts have worked with the early adopters of grid integration who have been interconnecting hundreds of Distributed Generation (DG) plants.
We have helped pioneer the development of impact studies for DER interconnection. Our technical report includes an outline of the project's feasibility, the technical specifications needed for the project, and an assessment of the impacts the project would have on the distribution grid.
Power System Transient Study
Power system transients caused by utility switching operations or lightning strikes to electric facilities have significant potential to damage equipment or disrupt operation. We provide transient stability studies and analysis of the response of a system to disturbances such as the loss of generation, line-switching operations, faults, and sudden load changes in the first few seconds after a disturbance.
The electrical power system is highly nonlinear and dynamic by its nature. The state of the system is changing continuously due to load demand response, circuit breaker operation, fault, and atmospheric disturbances. In such events, the system is forced to transition to a new state. During this transition, the electrical equipment will be exposed to fundamentally different voltages and frequencies, resulting in higher stress on the equipment. This added stress may lead to equipment failure and poses an increased risk to system reliability.
Electromagnetic Transient (EMT) Studies can provide great insight into expected power system overvoltages and overcurrents resulting from lightning strikes, switching operations, and fault conditions. EMT is a computer-based analysis and simulation tool used to determine voltage, current, frequency, and torque during the transient state of a power system.

Electromagnetic Transient Studies
Knowing the vulnerabilities of your system is critical to understanding its ability to return to normal or stable conditions after a disturbance and can help ensure stable, safe, and reliable power distribution.
Our EMT studies are supported by a state-of-the-art Real Time Digital Simulator (RTDS) and the results of tests undertaken in our specialized high-voltage laboratory. In full compliance with IEC and IEEE standards, we can perform the following studies:
- Comprehensive Insulation Coordination
- Temporary and Switching over Voltage
- Transient Recovery Voltage Study (TRV)
- Power System Resonance
- Sub Synchronous Resonance (SSR)
- Harmonic
- Capacitor Bank Switching

Substation Automation Lab and IEC 61850
No matter how well designed an electrical power system may be, faults can occur and this can lead to severe damage in installations or equipment. Defining an adequate protection system is an indispensable and integral part of power system design.
We assist you by defining data exchanged between devices in the substation, between the protection devices and the circuit breakers, and also between other closed-loop automated functions.
Our protection and control system verification laboratory is designed to help you meet a new set of global standards for IEC 61850 and, achieve significant savings with in-house integration and a “plug and work” approach. It also provides a comprehensive functional testing service for protection and control systems that is compliant with both IEC 61850, and legacy protocols.
