Smart Grid

Imperia designs smart grid systems to improve safety and reliability in the power grid.

Providing diagnostic and supervisory control capabilities for substations, these systems collect and analyze real-time data on the state of the grid. Then, the smart grid systems make the changes necessary to prevent adverse effects on power delivery.

Data collected by smart grid systems include loads, voltages, currents, and waveforms. Typically, the data and supervisory control signals of smart grid systems are transmitted over fiber optic cable, but secure wireless communication methods are available as well.

SCADA Systems and Substation Automation

Imperia designs SCADA functionality into electrical substations. SCADA is an acronym for, “Supervisory Control And Data Acquisition.” SCADA is used to affect physical change, such as the tripping of a breaker. Modern SCADA components are controlled via internet protocol (IP) signals, and are intricately related to information technology (IT) systems.

However, SCADA goes a step further than IT, by not just manipulating and storing data, but using it to physically control substations from remote locations. Imperia has designed SCADA rack configurations, rack wiring diagrams, controller interconnections, and patch panels.

Relay Protection & Control

Imperia is prepared to develop complete design packages for protection of transmission lines, distribution lines, transformers, generators, motors, capacitors, shunt reactors, series reactors, and buses for all switchyard configurations and all voltage levels – from 4.16 KV through 765 KV.

Arc Flash

Imperia is committed to helping our clients meet all requirements for Electrical Safety in the Workplace. Our staff has an in-depth understanding of requirements in NFPA 70E, IEEE Standard 1584, and NESC C2. Imperia has been developing Arc Flash studies for more than a decade. (The chronology of Arc Flash requirements reveals that the issue began in the petro-chemical industry, was formalized for other industries with the issuance of NFPA 70E as a standard in 2004, and was formalized for electric utilities with the issuance of NESC C2 in 2007).

In simple terms, Arc Flash studies consider available energy, working distance, and fault clearing time in the unlikely event that an electrical arc would occur when workers are repositioning electrical components.

Imperia is prepared to calculate the energy that can be released by an inadvertent, arcing type, short circuit; to calculate the energy that might impinge on nearby workers; and to specify the appropriate levels of protective clothing required.

Our staff has developed arc flash studies for a wide variety of clients. We have:

  • Walked down facilities to gain an understanding of equipment installations
  • Prepared short circuit studies that document short circuit current levels
  • Reviewed fuse, circuit breaker, and protective relay time current curves to determine fault clearing times
  • Developed studies to document incident energy levels
  • Recommended flash protection boundaries
  • Recommended protective clothing
  • Presented training to explain key principles of arc flash hazards
  • Assisted in the placement of Arc Flash warning signs designed to alert workers

Imperia has the experience to develop and enhance Electrical Safety in the Workplace programs. We can relate to your staff and explain in practical terms the expectation that everyone is entitled to a safe and productive workplace. We can provide examples of incidents and near misses that, although unlikely, highlight the need for diligence and care as we perform our daily work activities and the need to be aware of potential arc flash hazards.

Addressing Arc Flash Hazard

OSHA 1910.132(d) and 1926.28(a) requires that the “…employer shall assess the workplace to determine if hazards are present, or are likely to be present, which necessitate the use of personal protective equipment (PPE).”

Potential Exposure to Arc Flash

Although it may appear that arc flash incidents are uncommon, statistics show that the damage they cause is considerable. Bureau of Labor Statistics data shows several thousand cases of reported days away from work due to electrical burns, electrocution or electrical shock injuries, fires and explosions.
The exposure to arc flash depends on the following:

  • Arc flash hazard is a potential danger to workers near and around live exposed electrical parts
  • Work performed on exposed live equipment
  • Complexity of the task performed
  • Space restrictions
  • Tools and PPE used
  • Condition of equipment

Arc Flash Hazard Analysis Services

  • Evaluation of your electrical facilities
  • Create short-circuit study
  • Create protective-device coordination study
  • Updates/Create Facility One Line Diagrams
  • Determination of the incident energy exposure to the worker within the flash protection boundary in order to satisfy the requirements of NFPA 70E

Electrical System Studies and Analysis

Imperia is prepared to develop system studies, short circuit studies, protective relay setpoint analysis, load flow studies, voltage studies, ground grid analysis, forensic investigations, structure load analysis, cable pulling calculations, motor starting calculations, generator sizing, battery and charger sizing and a wide variety of other calculations, studies, and analysis needed to justify new installations, equipment retrofits, and continued operation.

Imperia can use models, programs and databases loaded on client supplied laptops; commercially available programs with Imperia developed models; or a combination or user supplied data and Imperia models.

Imperia has:

  • Analyzed load flow and system impacts when small combined cycle generation was connected to a networked distribution system.
  • Studied new switchyard configurations at Nuclear Power Plants.
  • Utilized client databases to evaluate protective relay settings when new generators were proposed to be connected to a 138 KV network.

  • Developed cable pulling calculations for low voltage, medium voltage and high voltage cables pulled through conduits, duct banks, cable tray, etc.

Fault Induced, Delayed Voltage Recovery Analysis

Since the Great Northeast Blackout of 2003, Imperia has been researching traditional power system models, power system load representations, and the design and operation of transmission and distribution systems. Our research indicates that the accuracy of today’s power system models need to be enhanced by the addition of new load models that more accurately represent distribution system customer loads during Fault Induced, Delayed Voltage Recovery (FIDVR) conditions.

At this time, Imperia is prepared to work with clients to evaluate:

  • Impact of remote, EHV, three phase short circuits on distribution system load models.
  • Need to upgrade models to understand transmission system performance with enhanced customer load models.
  • Cost effective system enhancements that mitigate local impacts when three phase faults occur at remote locations.

To uncover weaknesses in distribution system design and operation and the resultant impact on transmission system operability, Imperia’s Subject Matter Experts (SME) are prepared to:

  • Meet with client distribution system operations SME, transmission system operations SME, and protection and control SME to discuss risks and impacts.
  • Use client short circuit models to develop voltage profiles across the distribution system when three phase short circuits occur at remote locations.
  • Use client transmission system models to develop voltage profiles across the transmission system considering Fault Induced, Delayed Voltage Recovery.
  • Modify client distribution system models to predict Fault Induced, Delayed Voltage Recovery at selected distribution substations when three phase faults occur at remote locations.
  • Develop recommendations for corrective action.

These concerns are best illustrated using Figure 1 which shows:

  • Voltage along a distribution line is maintained at, or above, nominal value during peak load conditions (black line).
  • Voltage along a distribution line decays substantially during fault conditions at remote locations (red line).
  • Voltage along a distribution line does not recovery immediately when the remote fault is cleared.

The dashed lines in the figure below represent critical load voltages for HT – High Torque Motor Loads and LT – Low Torque Motor Loads. The concern is that existing load flow models represent motors as constant power loads. Our analysis indicates that the existing representation is adequate for low torque and variable torque mechanical loads, that is, fans and pumps. However, our analysis indicates that the existing representation is unacceptable for high torque mechanical loads, that is, air conditioners, refrigerators, and air compressors. Moreover, our analysis indicates that high torque motor loads will stall in less than 3 cycles (50 milliseconds) when a three phase fault occurs at remote locations.
