Power System Studies

The following listing is intended to give an overview of the variety of projects accomplished by Quadrelec Engineering. It is by no means comprehensive. Many of the coordination studies were later used for Arc Flash Hazard analysis.


Load Flow, Short Circuit, and Protective Device Analysis Study

Owner:     USACE Tulsa District and the Hydroelectric Design Center, Portland Oregon
Description:   

System studies for hydropower plants consisting of vertical and slant axis turbine generators. Studies were part of a major rehab or generator uprate projects. Studies became de facto standards for other similar studies.

Powerhouses studied include:

Webbers Falls Powerhouse,

Denison Dam Powerhouse,

Table Rock Dam Powerhouse,

Ft. Gibson Dam and  Powerhouse,

Keystone Dam and Powerhouse

Eufaula Dam and Powerhouse

Broken Bow Powerhouse

Tenkiller Dam and Powerhouse

Robert S. Kerr Lock, Dam, and Powerhouse

 

 

Arc Flash Study

Owner:     Green Country Energy, LLC, Tulsa,OK
Description:   

Arc Flash Hazard study for a 680+ MW combined cycle generation plant.

Owner:     U.S. Army Corps of Engineers
Description:   

Arc Flash Hazard studies for 179 sites including hydroelectric generation plants, reservoir control structures, navigation locks, parks, and office facilites

Protective Device Coordination Study
Owner:    U.S. Air Force, Lajes Field, Portugal  
Description:    System study for an entire Air Force base with on site generation system. Subcontract with the USACE Huntsville Division.
 

Load Flow, Short Circuit, and Harmonic Analysis Study

Owner:     Tinker AFB, OK
Description:    System study for a jet engine repair facility. Study was limited to the engine parts heat treatment area of the plant where motor failure problems were experienced. Involved subsystem of four unit substations.
 

Load Flow, Short Circuit, and Coordination Study

Owner:     Kwikset, Bristow OK
Description:    System study for an industrial manufacturing facility for door locksets consisting of 3 each 1-2.5-MVA unit-substations.
 
Protective Device Coordination Study
Owner:    Baptist Medical Center Oklahoma City, OK
 
Description:    System study for 600+ bus hospital system with four 750-kW emergency generators and three static transfer switches. Subcontract with C. H. Guernsey & Co. Oklahoma City, OK
 
Protective Device Coordination Study
Owner:    Southwest Medical Center, Oklahoma City, OK
  
Description:    Power system protective device study for a 365-bus system with three emergency generators and static transfer switches. Subcontract with C. H. Guernsey & Co.
 
Load Flow  Study
Owner:    Wolverine Tube, Shawnee, OK
 
Description:    Partial system study for copper tubing manufacturing plant consisting of 8 - 1000 to 1500-kVA unit substations. Total plant load 5-mVA. Recommendations of study improved voltage profiles within plant increasing plant throughput productivity 5-15%.
