Hedgehog Technologies designed and installed a demand response system for a remote community with the intent to match the community’s energy demand with the optimal generation efficiency. We expect a benefit of an up to 5% increase in efficiency. We worked alongside project partners Cooper Power Systems, Pagenet, CanmetENERGY and Pulse Energy Inc.
Distributed Generator Interconnection
By recapturing lost heat from a coffee roasting factory, the team at Hedgehog designed an induction generator and managed the interconnection process for a BC Hydro interconnection scheme.
Generator System Efficiency Study
To improve operations by 5% per year, Hedgehog evaluated generator efficiency and performance, installed fuel flow monitors and energy monitoring and recommended new set points and operational characteristics for a client in a remote community in northern British Columbia. The generators were dispatched more efficiently within reasonable safety margins.
Micro Smart Grid Integration
For a small, remote, off-grid community, Hedgehog Technologies designed smart grid infrastructure with AMI and demand response control that uses 2.0 GWh of annual energy.
Shore Station and Power Supply Design
Designed a 5kW, 1200 VDC power supply and network for subsea power transmission into the Strait of Georgia. Full factory acceptance testing and burn in were completed. The transmission distance is up to 100 km therefore careful transient and short circuit studies using cable models were conducted to properly protect the target and coordinate the shore breakers.
Transformer Leakage Current Isolation
Solved issue of continual ground faults due to excessive humidity in a specialised control station. Hedgehog identified the leakage path and isolated the 2000 VAC circuits to function with no faults in the high humidity environment.
Develop a Smart Grid Centre
Hedgehog’s team of electrical engineers worked with Powertech Labs to define and develop a smart grid centre for testing advanced utility infrastructure. The facility is capable of testing self-healing networks, distributed generators and alternate communications strategies.
Reduce Energy Consumption and Peak Demand
Hedgehog works with remote northern communities in central Canada to reduce and enhance their energy consumption. We follow a multi-step process that consists of:
(1) Creating community energy plans,
(2) Initiate energy audits,
(3) Establish conservation programs,
(4) Advise peak demand reduction strategies,
(5) Assist with installation of renewable energy solutions.
Transition to Renewable Energy Systems
Hedgehog assists remote communities to understand their energy needs and transition to 100% renewable, local energy supply. Our most recent project was to assess electrical energy usage on Haida Gwaii’s North grid and match it to systems of renewable energy sources in the area.
Manufacturing Plant Electrical Detailed Design
Created a detailed distribution and breaker coordination for a 50,000 sq. ft. manufacturing plant. Our solution included a detailed design of lighting control, plug power, as well as balanced loading preventing motor burnout and transformer overheating.
Production Failure Effect Mode Analysis
Reviewed production systems, conducted FEMA Analysis with production and design team, identified processes and systems failure points and implemented corrective action.
Design Motion Control and Advanced Manufacturing Systems
Hedgehog designed, programmed and verified a state-of-the-art motion control system to increase production capacity, reduce operator error and simplify long-term maintenance. The system was developed to be SCADA ready for ongoing production metrics and company production scheduling.
Create Electrical Systems for Explosive Environments
Designing to IEC-EX 60079.x international standards with IEC 61508 and IEC 61511 SIL rated equipment, Hedgehog designed a gas filling and decanting station. Our plans included full end- to-end design of energy systems, safety and control, created specifically for use in Australia. We used a range of isolation techniques including intrinsic barriers, explosion proof and control ventilation.
Achieve Manufacturing Plant Upgrade
Hedgehog prepared a manufacturing plant to move location. Our comprehensive services included developing single line, conducting a fire and safety code compliance audit and an equipment end-of-life review. In addition, we designed upgrades for controllers, panels and services.
Cable and DNV Compliance Support
Cable study, DNV compliance verification support (for international certification and insurance) and System Energy Budget completion.
Sensor/Controller EMI Noise Reduction
Hedgehog conducted a sensor noise and EMI elimination study with field tests before and after improvements to prevision load bank sensors for launch and recovery system.
Complete Energy Study
We undertook an energy study that included a power system study, breaker coordination, short circuit study, ground fault detector evaluation, isolation circuitry, pilot station design, system test and integration and IEEE 45 marine compliance verification support (for international certification and insurance). As part of this project we also completed a System Energy Budget and conducted an emergency life support system study.
Deliver System Modernization
We completed a System Energy Budget, conducted an emergency life support system study and supported system and integrations. We also completed DNV compliance verification support (for international certification and insurance).
Design of Hard Suit (Technical Support and Offshore)
We completed a System Energy Budget, conducted an emergency life support system study and supported system testing and integrations. We also completed DNV compliance verification support (for international certification and insurance).
