Control Modernization for SFC Drives

Engineered solutions for complex drive and control applications

PROVEN DRIVES CONTROL TECHNOLOGY

If you currently rely on vintage SFC drive controls like

VME or Syconumdrive controller, you cannot ignore

the risk of obsolescence. A reliable and cost-effective

upgrade can save you the time and expense of a

complete system’s replacement.

This simple upgrade will modernize your controls and

data interfaces, substantially improving control

capabilities and performance. Extensive diagnostics

and comprehensive testing can make systems easier to

maintain, with GE’s outstanding drive services helping

you get the greatest possible value from your MV drives’ controls.

The external control interface -GE’s P80i Control

System toolbox-is widely considered as one of the best

tools for configuring, troubleshooting and maintaining

legacy SFC drives and controls.

IMPROVED CONTROL CAPABILITIES & PERFORMANCE

A well planned and executed upgrade by GE Power

Conversion experts can save time and cost of an

extensive system replacement and help you extend the

life of critical power equipment.

Digital Energy Intellix MO150 Key Benefits

The Intellix™ MO150 transformer monitoring system, from GE Energy, is an intelligent, cost-effective

solution which provides comprehensive monitoring and interactive transformer condition diagnostics,

to provide early warning of incipient failure conditions.

Based on field-proven technology, the Intellix MO150 uses various sensors such as the Hydran™ and

state-of-the-art transformer mathematical models based on IEEE® or IEC® standards, to provide real

time information on the overall performance of the transformer to assist utility operations managers

and system operators in making critical decisions.

Key Benefits

On-line monitoring and performing real-time, transformer diagnostics can help reduce the risk of

unexpected and sometimes catastrophic failures. This also helps you avoid expensive replacement

and clean-up costs, unplanned downtime and overall improvement in asset. Reliability. Early detection

of potential transformer problems is vital tothe lifespan extension of critical transformers and brings

significant business and operational benefits:

• Reduce inspection and maintenance costs by confidently stretching out the time between routine

maintenance activities

• Optimize equipment life by monitoring cooling system performance

• Reduce the probability of an unplanned outage with continuous condition monitoring

• Provides greater lifespan confidence through the use of on-line model computation providing real

time transformer condition information

• Defer major replacement costs by optimizing your transformer’s performance and extending its

lifespan

IC697ALG230 Base Converter Module Expansion Bus sampling technique

This sampling technique continues until all available

expander channels (16 x number of Expander mod

ules) have been scanned, at which time the sequence

starts over.  The number of analog scans required to

include sampling of all expander channels is equal to

the total number of Expander modules x 16 (16 chan

nels per Expander module) in the system.

With no Expander modules present, each base con

verter channel is updated once every 2.4 milliseconds.

With one or more Expander modules present, this

update time increases to 2.8 milliseconds.

Each expander channel is updated every 2.8 x N ms

(where N = total number of Expander channels pres

ent).  Note that the scan sequence is free running and

it cannot be synchronized with any external event.

Also note that all inputs of an Expander module will be

scanned even if they are not being used.

IC697ALG230 Base Converter Module Input Sampling Techniques

Input Sampling Techniques

The objective of the input sampling technique for the

analog subsystem is to provide 8 input channels on

the base module that have a fast (approximately 3 ms)

update rate and additional expander channels that are

updated less frequently, but have a lower cost per

channel.

Operation is such that the base module initially up

dates all eight channels plus one expander channel.

On each successive scan all eight channels of the base

converter are again updated – plus the next expander

channel in sequence.  After 16 analog input scans all 16

channels of the first expander have been sampled; on

the next scan, all eight base converter channels plus

the first channel of the next Expander module are

scanned.

IC697ALG230 Base Converter Module Expansion Bus

Expansion Bus

The bottom six terminals (35 through 40) on the ter

minal board on the Base Converter and Expander

modules make up an expansion bus for connecting

input Expander modules to the Base Converter mod

ule.  An analog multiplexer on the Expander module

acts as a switching circuit to connect analog inputs,

one at a time, to the A/D (Analog to Digital) converter

on the Base Converter module.

Each expander channel is updated every 2.8 x N ms

(where N = total number of Expander channels pres

ent).  Note that the scan sequence is free running and

it cannot be synchronized with any external event.

Also note that all inputs of an Expander module will be

scanned even if they are not being used.
