System Applications

Distributed Generation

System 2000 Distributed Generation (DG) Switchgear provides the capability of synchronizing single or multiple generators to the utility grid to allow peak shaving or co-generation operation with local or remote communicative control. Distributed Generation Systems can be supplied with fully automatic operation and closed transition, soft power transferring control.

Standard designs are available to fit most applications and can be adapted to fit an owner’s specific requirement. Custom engineered systems and design recommendations are available for those applications requiring a unique design approach. The System 2000 series of products can be utilized with diesel or gas engine generator sets, as well as gas, steam or hydro-electric turbines. By incorporating advanced communication interfaces, System 2000 products can operate in harmony with any site or building management system, providing maximum equipment utilization and total energy management.

The System 2000 Distributed Generation Switchgear can be applied to many types of applications in the power generation industry such as hospitals, data centers, water/wastewater treatment plants, casinos, correctional facilities and many more. Thomson Power Systems DG Switchgear can be applied to new installations as well as existing systems where generators are upgraded for parallel operation with the utility supply.

Emergency Standby

Automatic Standby Switchgear Systems provide control of single or multiple generator sets to provide automatic standby power during a utility power failure. Emergency standby switchgear can be designed with integral transfer systems between the utility supply and emergency bus or with an external distributed transfer switch scheme.

Numerous standard transfer control schemes are available to meet your specific project requirements. Manual synchronizing is provided in the event of failure of automated control.

Load demand starting can be incorporated to maintain optimal efficiency and reliability of your gen-sets during a power failure. Load management schemes are provided to prevent costly and dangerous downtime by limiting potential over load conditions.

Design features can be incorporated to meet specific industry standards such as:

Uptime Institute certified Tier II, III and IV Data Centers:

  • Primary Power System Design Philosophy
  • Concurrently Maintainable
  • Multiple, Independent, Physically Isolated

UL/CSA Critical Care Health Facilities:

  • CSA Z800-11
  • Vital Branch Transfer to Emergency Power in 10 Seconds
  • Delayed Vital Branch Transfer to Emergency Power in 2 Minutes

Marine Standards:

  • Det Norske Veritas (DNV)
  • Lloyds Registry
  • American Bureau of Shipping

Prime Power

Prime Power Switchgear Systems provide power and control for applications where local utility is unreliable, unavailable, or uneconomical to install. Prime power sites require unique control solutions because of their critical nature. These systems can incorporate automatic synchronizing, soft transfer, fuel economizing, or run time hour balancing. The systems can also be provided with modem communication for remote monitoring, control, data-logging, and alarming.

Applications include:

  • Marine - on board power generation
  • Village or island applications system acts as the utility
  • Mining, offshore platforms, gas plants, and remote refineries, providing on-site power for production

In locations such as remote mining or gas plant operations, utility power is nonexistent. A multiple-unit, auto-synchronizing system will provide continuous reliable power for site operations and production systems. The system can control multiple units for auto-synchronizing, and protections. The controls can automatically start and stop generators as required, based on plant demand, improving system downtime and facilitating maintenance.

Thomson Power Systems’ Marine Switchgear is designed to meet the additional requirements of the applicable marine standards such as Lloyds, DNV, or ABS. These standards deal with issues like extreme temperature ranges, vibration, serviceability, and fire proofing.

Seismic Switchgear Configuration

Thomson Power Systems Switchgear and automatic transfer switches have been tested to withstand seismic events as defined by the International Code Council Evaluation Service (i.e. ICC-ES) AC156 Standard. This test standard was developed specifically for non-structural components such as electrical equipment that must withstand specific forces of a seismic event when simulated in a shaker table test environment. The AC156 Seismic test standard has been developed in accordance with the International building Code (i.e. IBC) section 104-11.

Testing Specifications:

Desing Regions Ss = 342%
Shake Table Uni-Axial, 3 orthogonal directions
Sine Wave Tests Multi-direction, 0.1g amplitude, 33.3 hz to 1.3hz Range
Operation Tests Pass = Positive high potential test, continuity test and functional operation
