Won 1st place in special projects category of the American

Consulting Engineers Council of Colorado Excellence Awards

The Polyolefin Company (Singapore)

• First major polyolefin manufacturer in SEA

• Operational since Feb 1984

• Largest polyolefin producers in region

“Reliability of our facilities is translated to the continuity in the supply of high quality products to our customers.”

The Polyelofin Company (Singapore)

The Challenge:Replacing an old fault recorder that monitors the power provided by the PowerGrid.

The Solution:

Creating a power quality measurement and analysis system using LabVIEW and PXI.

ConclusionThe previous voltage dip recorder is costly and not as user-friendly compared to the current one. It can only detect changes in the contact and not the details of the values.

Besides that, the cost of the National Instruments voltage dip recorder is only about half of the cost of the previous one.

Remote Gas Monitoring System (Thailand-Singapore)

PACs Control Inspection of Nuclear Power Plants

• Challenge• Designing a single, flexible system to control many different inspection and maintenance tools for nuclear power plans within the limited space and

harsh environment of nuclear reactors.

• Products• LabVIEW Real-Time, PXI/CompactPCI, Motion, and Vision

• ResultsWith the reliability of LabVIEW Real-Time, modularity of PXI, and broad range of I/O, this solution ensures operation in harsh nuclear power plant environments. We have deployed the system in four U.S. nuclear reactors so far in 2004.” Matt Jewett, R Brooks Associates, Inc.

The Diablo Canyon Nuclear Power Plant in San Luis Obispo, California, is one of the locations where R. Brooks has deployed the LCS to perform inspections.

What Is Electrical Power Monitoring?

• Power metering

– Demand side management

• Power factor

• Power quality

• Sequence of events recording

• Substation monitoring

• Grid monitoring

Power Measurements

14

Power Factor

•Electrical Power measured in watts or kilowatts•Amount of Power applied over a period of time is usually expressed as kwh•AC power system voltage and current in pahse wil be maximum power•Eg 15deg out of phase = 97% useful work•Degree in which voltage and current are out of phase is power factor

Power Quality

•Many Facilities today have sensitive computerized equipment of

telecommunication equipment

•Use ground as reference for all their operations and connect throughout

the plant

•Susceptible to Ground differences and power quality problems

•Many people believe power quality problems come from power supplier,

but significant amount are introduced inside the plant

15

RMS Voltage Variations•Sag (Dip)

•RMS voltage level drops to below 90% of the typical level but is greater than 10% of the

nominal voltage

•Most common power quality disturbances usually caused by problems within facility

•Common cause by load variations or improper wiring

•Eg: Starting an electrical motor with a very high inrush current (6 to 10 times normal

operation current)

•Swell (Surge)•Voltage increases to greater than 110% oft the typical RMS voltage

•Rapid decrease in load (eg: electrical heater shuts off)

•Interruption•RMS Voltage falls to below 10% of the nominal voltage

•Fault protection from a circuit breaker or from a fuse

•May be traced to loose wiring connection

RMS Voltage Variations

•Sustained Undervoltage

•Sags longer than 3 minutes

•“brown out”

•Improper transformer tap settings or problems from electrical utility

•Sustained Overvoltage•Swells longer than 3 minutes

Sags and Interruption can cause problems in a facility by shutting down

sensitive electronics, computers or process equipment

16

Harmonics

•Modern electrical equipment uses switching power supply

•Introduces nonsinusoidal load which pulls current in short pulses during

every cycle

•Pulling power in a nonlinear manner introduces harmonics in the

electrical system and can overheat power distribution transformers

•Electrical systems are specially susceptible to triplen harmonics

•Effect is additive

Dangerous Harmonics at 3rd, 6th, 9th

17

Harmonics

• Ordered list that shows the exact time of day that some event occurred

• Produces a chronological record that can be used for analysis and verification of system operation

• Often very precise, down to the millisecond level

What is Sequence of Events Recording?

18

• Time stamp events such as breaker trips, reclose operation, overvoltage conditions, and operator initiated actions

• Provides a detailed historical record for post fault analysis and proof of system operation

• Can be used to see how the system operated under fault conditions and during restoration of power

• Can record every change of state that occurred within the system

How is SOE recording used in Electrical Power?

Very High Speed Control & Monitoring

• Safety• Speed, pressure

• Diagnostics• Flow, torque

• Troubleshooting• Process variations
