* Features

2. Capable of accepting up to four assignments, each with its own C.L. current limits
3. Speed control for shunt or series DC motors

10. No field calibrations
11. Voltage and current outputs for metering
12. Alarm indications for SCR over-temperature and blown fuse
13. Automatic bridge shutdown for blown fuse condition

* Power Limiting From Generator Control:

I-Drive Power Limiting protects the diesel engine/generator set(s) from dropping "Off Line" due to an overloading. When maximum KW or KVA capacity has been reached, the system "phases back" the outputs of the SCR drives connected to the AC Buss, and thus prevents the generator sets from dropping off line due to an overload.

* Current Limit Circuit

The I-Drive SCR Control Module accepts four different current limit settings, which corresponds to the four possible assignments of the SCR drive. The I-Drive SCR DC cardrack test panel has four potentiometers where the Current Limits are set. The current limit settings are a separate module from the D/C module which allows changing the D/C module without resetting current limits.

* Remote Current Limit

The I-Drive SCR Control Module allows for a remote current limit input. This setting is used with the current limit setting of the Rotary Table.

Firing Circuit Regulator:

The I-Drive Firing Circuit Regulator works in conjunction with the AC Buss Phase Sensing and the Six Gating Pulse circuits. The SCR firing pulses are referenced to the Three AC Lines, and timed to trigger the respective SCR's at the correct instant.

There are six firing pulses (each spaced 60 degrees from the previous) in each cycle and all are adjusted simultaneously by the firing enable circuit to get the correct SCR firing angle.

* Inverse Timed Over-Current Module (plugs into the DC cardrack)

This feature allows the I-Drive SCR drive to deliver more current for a short period of time than what is preset with the current limit Calibration as set on the DC cardrack test panel. This feature can be used in situations where high current is needed for short periods of time, I.E. for a drawworks motor. The amount of overcurrent allowed is set at the Timed-Overcurrent Module, from 110% to 130% of the present current limit for approximately 60 seconds. After the 60 seconds period, the current will revert to the normal current limit as set at on the I-Drive DC cardrack test panel so as not to damage or overheat the SCR bridge.

* Alarms

There are two alarms in the I-Drive SCR drives:

Over-temperature
Blown Fuse

The I-Drive SCR Bridge has the capability of detecting:

1. Over-temperature: When the SCR Blower is lost or the SCR house internal ambient temperature rises to an unacceptable level so that proper cooling of the SCR’s is not possible, a set of thermo-switches, mounted on the SCR bridge heatsinks detect when the temperature goes above 70 degrees C and signals an alarm condition

2. Blown Fuse: The SCR bridge has a set of semi¬conductor fuses for the protection of the SCR's. If any of the fuses open, the FFAS (fuse failure alarm signal) is activated (isolated contact closure) and the firing pulses to the SCR bridge are automatically inhibited

* Zero Throttle Interlock:

All the controls ARE interlocked. If the bay is re-assigned during power on, the bays shut down and will not restart until their respective throttles have been returned to the ZERO (off) position. This includes the foot throttle.

* SCR Drive Construction Specifications

The I-Drive SCR drive is of modular design, compact, NEMA type 1 A construction WITH DRIPSHIELDS, front access only. The D.C. control module contains the circuitry necessary to control the SCR Bridge’s output. The module is interchangeable between all I-Drive SCR systems. The module is furnished with no adjustments necessary. The module is easily disconnected for replacement should the need arise. This makes for a minimum of “down-time” should a failure occur.

The I-Drive SCR cabinet is so designed so as not to have any pockets of abnormally high temperature.

The I-Drive SCR Bay cooling is assisted by a squirrel cage blower forcing air in the direction from bottom to top of the cabinet. Air is drawn in through a filter in the lower section of the front door. It then proceeds over the contactors, DC buss, and into the blower intake. The blower’s output airflow goes directly into the plenum below the SCR bridge, into the bridge heatsinks (the point of the most air flow resistance), out the top of the bridge, upward past the circuit breaker and AC buss, and out the top of the cabinet.

The I-Drive SCR Bridge is composed of three (3) identical and interchangeable modules (Phase Cells). Each Phase Cell has an AC input flag, a minus DC output flag, and a plus DC output flag. In the Phase Cells the discrete SCR devices have heatsinks on both sides. Thermodynamics proves that this allows the SCR devices to operate at a lower temperature than single sided “bricks” for the same device current. The lower the operating temperature, the more reliable the SCR device is. The system is designed for low maintenance and to operate in ambient air temperature up to 50 degrees C without air conditioning.

* Dynamic Brake

The I-Drive drawworks dynamic brake will slow the drawworks motors from full speed within eight to ten seconds after the foot throttle is released. The power of the free wheeling motor is fed back into a resistor bank. During normal operation the dynamic brake system is non-operative, and the drawworks is either OFF or operating at the desired cathead speed. If however, at any time the motor speed is higher than the DW throttle speed setting, and the foot throttle is OFF, the dynamic brake system is actuated, reducing the motor speed to the DW throttle setting.

* Driller’s Foot Throttle

The I-Drive foot throttle is constructed of rugged stainless steel throughout; built to withstand the environment normally encountered on the rig floor.

The foot throttle is a compact unit constructed of stainless steel. The unit is designed for air purging for use in a Class 1, Division 2 area.

* Driller’s Console

The I-Drive Drillers Console will be NEMA type 4X construction of #316 stainless steel1 outdoor weather proof and provided with air purge/pressurization fittings to allow use in a Class 1, Division 2 hazardous area. All assignment switches, hand throttles and controls will be front mounted on the door. All meters, instruments and annunciators will be mounted behind the front door with a safety glass view window provided to view the meters and instruments, etc. The door will be attached with stainless steel hinges and positive latching stainless steel latches.

The exterior of the building will be cleaned with a sweep blast of sand to remove scale and oxidation. The exterior coating will consist of a sub-coat of zinc rich primer, and covered with a coat of polyurethane, color white. The interior floor of the building will be covered with black colored epoxy enamel. The skid base will be primed and painted black.

The transformers, air conditioning units and dynamic brake grid resistors will be mounted at the end of the building.

Building will also be equipped with hand rails and access ladder for the roof.

E. PLC CONTROL SYSTEM
A complete PLC Controller System (hardware and software) to control and monitor the SCR system. The system will include:

1 ea Control Power Transformer & Power Conditioner (600:120V)
1 ea Touch Screen Color Monitor (mounted on the SWBD)
1 set PLC hardware (CPU, Pwr Supply etc.)
1 set IECS Software customized for this system

At a minimum, the software will be designed to display the following SCR System operation parameters on the monitor:

PLC Communication Status
Ground Fault Status
Generator On-Line/Off-Line Status
SCR ON-Line/Off-Line Status
SCR Bridge Blown Fuse Indicator
SCR Bridge Over-Temperature Status
SCR Bridge Amp (0-2000 A)
SCR Bridge Volts (0-750 VDC)
Active Power Limit Indicator
