Maui Electric Follows HECO Lead on PLC-based Automation

Maui Electric Co. Ltd. (MECO), a subsidiary of Hawaiian Electric Co. Inc. (HECO), provides electricity and operates the electric system on the Hawaiian island of Lanai. Barely 10 miles across, and about that same distance from neighboring Maui, Lanai has seen its electrical power demand double within the past 10 years. The increase is the result of continuing development of first-class visitor accommodations. These include two luxury hotels, two championship golf courses and two up-scale residen

SAP Customer Care and Service Extends Functionality

Last year SAP, the Walldorf, Germany-based software giant, introduced its own utility-specific customer information system (CIS) which integrates with its R/3 software, a client/server business software. If the new CIS is as successful with utilities as the R/3 software has been, SAP will have a hit. According to SAP, there are currently more than 350 utilities in Europe, the Americas and the Asia-Pacific region using the R/3 system with several involved in the piloting of this system, called IS

Customer Information Systems Change Roles in the 21st Century

As the ground rules for utility industry deregulation are being laid out in the late 1990s, uncertainty and fear, as well as opportunity accompany them. The conditions for a competitive deregulated environment are distinct in every region of the country and abroad.

Looking at Utility Assets in a New Light

The deregulation of the utilities industry proves to be more of an ongoing evolution than a new permanent state. Adjusting business practices and policies to the proposed new environment is not a one-time task. Utilities, therefore, need to set their strategies for a continuing series of bold and creative initiatives employing all of their assets.

Deregulation Key to SCADA/EMS Growth

Through the years, SCADA/EMS has grown into a mature system providing valuable information and operational procedures to utility system operators. The SCADA/EMS systems have progressed from being large mainframe computer systems to today`s super fast PCs. The systems that were used in the past were closed-architecture systems, meaning that any sort of update or modifications often required a total reworking of the system. Any modifications to the systems were costly and very time consuming. Util

IEDs Expand Substation Automation Capabilities

Substation automation is not a new concept. Substations have been equipped to perform automatic reclosing, automatic bus sectionalizing, automatic load transfers, automatic capacitor switching and many other functions for many years. In the past, however, these and other functions were implemented using a combination of control panels, auxiliary relays, switches, lights, meters, transducers and extensive wiring and cabling.

Change Management Helps Power Year 2000 Effort

Illinois Power, a $5.7 billion energy generation and distribution company in Decatur, Ill., improved the way it managed its mainframe code and software development in order to successfully meet Year 2000 compliance requirements.

Alarm Monitoring & Notification System

The ADAS DiaLog alarm monitoring and notification system, developed by Antx Inc. automatically phones or pages up to 16 separate numbers from a single or series of alarm conditions. DiaLog continues to call, giving user-recorded messages, until all alarms are acknowledged, ensuring that appropriate personnel are notified of critical conditions.

Power Quality Measurement

Siemens Power Transmission & Distribution has introduced SIMEAS, a line of power quality measurement products designed to ensure system power quality, uniform load distribution, fault and harmonic imbalance recording and other power management capabilities. Designed for power stations and industrial and commercial installations, SIMEAS multifunctional units document power control quality while recording all event anomalies.

Power Disturbance Pager

The 3100 PQPager detects and records electric power disturbances that damage and disrupt PCs, telephone PBX systems, cash registers and other sensitive customer loads. When installed by a utility power quality engineer, the instrument grabs power line sags, swells, transients and interruptions, and promptly reports the problem to pagers. A unique built-in voice-mail-like feature eliminates the need for a computer.
