Operator interface

Functional setup and operation of the NGC8206

is accomplished by using a graphical user’s interface software

package called PCCU 32 (supplied with each unit) operating on

a laptop PC in a Microsoft® Windows® environment. The

“Windows®” utilities, combined with software designed

specifically for the NGC8206, provide a powerful tool for

operations, diagnostics, and downstream data handling.

The PC can be directly connected to the NGC8206 via an

RS-232, USB, or Ethernet connection, or indirectly by remote

telemetry (phone modem, radio, cell phone, satellite, etc.).

The user is prompted through push-buttons, drop-down

boxes, wizards, and dialog boxes for setup, operations, data

collection and monitoring.

In addition, the unit has an optional ¼ VGA interactive display

screen allowing the user access to basic analysis data. The

user can also accomplish most of the “operator” functions

from the front panel display with out the use of a laptop PC.

The “Run-Hold-Calibrate” functions can be done via a magnet

interface through the explosion proof glass in the display.

Sample conditioning system

The integral stream selector for the NGC8206 allows sampling

up to four (4) different natural gas streams. Up to two of these

sample streams can be designated as the “calibration/

validation sample”. Optional sample conditioning modules are

available to address natural gas streams that need additional

filtering and “speed loops” to reduce sample transport lag times.

In addition, the unit has an optional ¼ VGA interactive display

screen allowing the user access to basic analysis data. The

user can also accomplish most of the “operator” functions

from the front panel display with out the use of a laptop PC.

The “Run-Hold-Calibrate” functions can be done via a magnet

interface through the explosion proof glass in the display.

Historical data

The Portable NGC is designed to retain historical data. This

data can be used for custody transfer needs, verify

transmitter operation over time, and provide a limited data

backup for communication link reliability.

In addition, various CSV file outputs are available to download

the analysis data into spreadsheet based company specific

data sheets, and outputs to 3rd party gas accounting

packages.

Equipment

The equipment used for this analysis consists of the standard

NGC8206 mounted in a powder-coated box. The equipment

used for this analysis consists of the standard NGC8209

mounted in a black case. It is recommended that the unit be

left in an operational mode while transporting.

All the valves, gauges, inlet ports, and PCCU32 (the laptop

driven man-machine interface) connectors are bulkhead

mounted on panel to provide the technician with ready access.

Description

The truck is moved as close to the sample point as is

practical. A flexible sample line is then uncoiled and attached

to the probe in the flowing natural gas pipeline. If the dew

point of the gas or the weather demands it, this flexible

tubing must be heated. A sample of the gas is extracted from

the probe in the line, purged through the flexible line and then

transported to the analyzer. There it is processed for particle

removal and phase integrity, injected onto the

chromatographic columns where component separation

occurs. These components are then quantified by peak

integration and concentration is calculated. The other data of

interest is then calculated from these concentrations.

Introduction

This data can be used for flow computers, RTU’s, gas

accounting systems, and SCADA systems for the energy,

AGA3. 7. 8. and 10 calculations at the meter site. This data

output can be a CSV file format so that analysis data systems

can easily incorporate the information. The number of runs

and the number of averages can be selected.

The averaged output can be formatted to be accepted by a

3rd party gas accounting software system, allowing

automatic downloads of the analysis data. Analysis done on

site is valuable because:

• Transportation of DOT regulated gas cylinders is avoided

• Time and cost of subsequent laboratory analysis

• Problems with sample handling

• Economic solution for gas quality measurement when the

gas volumes are too low to justify on-line chromatography

The RET670 also features pole slip protection, which detects and evaluates pole slips occurring in the power system and takes the necessary action.

Sections of the power system that are swinging away from each other can be separated by

the line closest to the center of the power swing, allowing the two systems to remain stable when separated.

The RET670 can be used with the IEC 61850-9-2LE process bus with up to six Merge Units (MUs).

Advanced logic functions allow user logic to be programmed with graphical tools to enable special

applications such as automatic opening of disconnect switches in multi-breaker arrangements, closing of breaker loops and load transfer logic.

Logic can be monitored and debugged online in real time for testing and commissioning.

Communication via fiber optic connections ensures immunity to interference.

Six software packages are defined for the following applications:

– Transformer backup protection (A10)

– Voltage control (A25)

– Single-breaker, two-winding transformers (A30)

– Double-winding transformers with multiple circuit-breaker arrangement (B30)

– Three-winding transformers in single-breaker arrangement (A40)

– Triple-winding transformer in multi-breaker arrangement (B40)

The optional functions are not configured, but a maximum configuration with all optional

functions is available as a template in the graphical configuration tool.

Templates for alternative configurations for auto-transformers are also available.

The analog and trip I/O are pre-defined for basic use and come standard with one binary input module and one binary output module.

The binary I/O can be added at the time of ordering, depending on the needs of the application.

the other signals need to be set up according to the needs of the different applications.
