Power Quality Problems on Rigs Critical Federal Signal loads require clean, regulated, uninterrupted power to operate.Critical Federal Signal loads require clean, regulated, uninterrupted power to operate. Diesel Generators are subjected to a constant step load change every time the top drive motor starts or stops (which is frequent) Diesel Generators are subjected to a constant step load change every time the top drive motor starts or stops (which is frequent) 3 Phase, six pulse SCR motor controllers produce power for the top drive motor.3 Phase, six pulse SCR motor controllers produce power for the top drive motor.

Voltage Fluctuations from Generators Voltage Sag created when top drive motor starts to move; loaded generators accelerate to supply power.Voltage Sag created when top drive motor starts to move; loaded generators accelerate to supply power. Voltage Surge created when the top drive stops, the generator “overshoots” and the governor tries to slow the generator down.Voltage Surge created when the top drive stops, the generator “overshoots” and the governor tries to slow the generator down. Step load changes on generators result in short term voltage sags and surges.Step load changes on generators result in short term voltage sags and surges.

Voltage Fluctuations From Generator

Wave-Shape Faults Also, during these step load changes on the generators, the frequency (60Hz nominal) varies slightly as the generator speed changes. 6 Pulse SCR controllers on the top drive motor distort the waveshape from a perfect sine wave, and introduce severe notching and transients.

Using a Commodity UPS in a harsh electrical environment If the UPS cannot correct for the voltage, wave shape or track frequency, it switches to batteries to protect the load.If the UPS cannot correct for the voltage, wave shape or track frequency, it switches to batteries to protect the load. If the UPS is subjected to this electrical environment constantly, it runs on its batteries until they are depleted and drops the load.If the UPS is subjected to this electrical environment constantly, it runs on its batteries until they are depleted and drops the load.

Why won’t a commodity UPS survive in this application? Testing has shown that the voltage conditions on the rig exceed the standard input window of a commodity UPS during a majority of their operating time. These UPS topologies use their batteries to supply the load continuously and are not effective when power fails.Testing has shown that the voltage conditions on the rig exceed the standard input window of a commodity UPS during a majority of their operating time.

Only a robust/hybrid topology UPS should be used to protect critical loads in the electrical environment common on oil rigs. The EDGE will protect the load without abusive use of the batteries. Ideal for safety critical systems where reliability is critical.Only a robust/hybrid topology UPS should be used to protect critical loads in the electrical environment common on oil rigs.
